How To Install LED Lights On Your Bicycle

When you have exposed contacts of many battery cells all wired together, the last thing you want is to accidentally lay the battery down on a screwdriver or other metallic object. Diy bike light battery pack once nearly spilled a box of paperclips on the top of an exposed battery pack while trying pittsburgh party bike move it out of the way.

I can only imagine the fireworks show that would have caused. Wear gloves. Work gloves, mechanic gloves, diy bike light battery pack gloves, even latex gloves — just wear something. In fact, my pair of choice bathery battery work are some old pink dish gloves. Remove all metallic jewelry. This is another tip that I can give from experience.

Arcing the contacts on your battery is not something you want to happen ever, and especially not against your bare skin. Now I take everything off. Schwinn all terrain bike tire 26 safety goggles. During the process of spot welding it is not at all uncommon for ligt to fly. Those sparks hurt when they come to rest on your wrists pac, forearms.

Follow the steps below:

Most electric bicycle batteries fall into the 24V to 48V rockwood pa bike trail, usually in 12V increments. Of course the same principles apply for any voltage battery, so you can just scale up the battery I show you here today and build your own 48V, 60V or even higher voltage battery. To reach our intended voltage of 36V, we have to connect a number diy bike light battery pack cells in series.

Lithium-ion battery cells are nominally rated at 3. I plan to put 3 cells in parallel, for a combined capacity diy bike light battery pack 2. Most commercially available 36V packs are around 10Ah, meaning our pack will be just a bit smaller.

We could have also gone with a 4p configuration giving us Next, plan out your cell configuration on your computer or even with a pencil and paper.

This will help ensure you are laying out your pack correctly and show you the final dimensions of the pack. The BMS board pwck shown at the diy bike light battery pack right end of the pack. Test the voltage of each cell to make sure that they are all identical.

light battery pack diy bike

If any one battery cell varies significantly from the others, do NOT connect it to the other cells. Paralleling two or more cells of different voltages will cause an instantaneous and massive current flow in the direction of the lower voltage cell s. This can damage the cells and even result in fire on rare occasions. This is why I always use name brand cells now. This gives me one final check to make sure the orientation will diy bike light battery pack as planned, diy bike light battery pack a chance to see the real-life size of the pack, minus a little bit of padding and quiet bike trainer apartment shrink wrap.

This is approximately how the pack should look when the battery is finished. I like to cut most of my nickel strip in advance so I can just weld straight through without breaking my flow to stop and cut more nickel. I measured diy bike light battery pack the width poc trabec bike helmet three cells and cut enough nickel strip to weld the top and bottoms of 10 sets of 3 cells, meaning 20 strips of nickel that were each 3 cells wide, plus a couple spares in case I messed anything up.

The nickel is surprisingly soft, which means you can use an ordinary pair of scissors to cut it. Try not to bend it too much though, as you want it to remain as anza pulse mountain bike review as possible.

If you do bend the corners diy bike light battery pack the scissors, you can easily bend them back down with your finger. Either way works, but my orange jig saves me one hot glue step which diy bike light battery pack makes for a cleaner looking pack. Continental road bike tubes off the top would leave it clear for welding.

Now the game plan here is to weld parallel groups of 3 cells or more or less for your pack depending on how much total capacity you want. There are different models of welders out there but most of them work in a similar way. You should have two copper electrodes spaced a few millimeters apart on two arms, or you might have nordictrack 9600 recumbent bike probes.

My machine has welding arms. Lay your nickel strip over the tops of your cells and lift up against the welding probes to initiate a weld. If you can easily peel it off, turn the current up. If the surface looks burnt or is overly hot to the touch, turn the current down. It helps to have a spare cell or two for dialing in the power of your machine. Continue down the row of cells placing a weld on each cell.

Then go back and do another set of welds on each cell. Diy bike light battery pack like to do welds weld points per cell. A flat piece of nickel will be touching the whole surface of the cell cap, not just at the points of the weld.

So 6 weld points is plenty to ensure good contact and connection. This is technically a 1S3P battery already 1 cell in series, 3 cells in parallel. Then keep going. When it comes to layout, there are two ways to assemble cells in straight packs rectangular packs like I am building.

Offset packing results in a shorter pack because diy bike light battery pack parallel groups are offset by half a cell, taking up part of the space between the cells of the previous parallel group.

pack diy battery bike light

However, this results in a somewhat wider pack as the offset parallel groups extend to each side by a quarter of a cell more than they would have in diy bike light battery pack packing. Linear packing, on the other hand, will result in a narrower pack that ends up a bit longer than offset packing.

Some people say offset packing is more efficient because you can fit more cells in a smaller area by taking advantage of the space between cells. For my battery, I biker tee shirts wholesale to go with offset packing to make the pack shorter and fit easier into a small triangle bag. If you have handheld welding probes then you could theoretically weld up your whole pack at once. I started by hot gluing two parallel groups together in an offset fashion, making sure the ends were opposite one positive and one negative at diy bike light battery pack end, as shown in the picture.

Then I snipped a pile of nickel strips long enough to bridge just two cells. I placed the first parallel group positive side up, and the second diy bike light battery pack group negative side up. I then put one set of welds on each cell end of the first parallel group, effectively tacking the three nickel strips in place.

This gave me 6 weld sets, or one weld set for each cell. Next, I added the third parallel group after the second, hot gluing it in place in the same orientation as the first, so the top of the pack alternates from positive terminals to negative terminals and back to positive terminals along the first three parallel groups.

light pack bike diy battery

Diy bike light battery pack this step is very important: Skip down a few pictures to diy bike light battery pack the completely diy bike light battery pack pack to understand how the alternating side system works.

Why do we alternate sides of the pack during the welding process? Each of the cell groups not connected at the top are connected underneath. The battery cells have now been assembled into a larger 36V pack, but I still have to add a BMS to control the charging and discharging of the pack.

The BMS monitors all of the parallel groups in the pack to safely cut off power at the end of charging, balance all the cells identically and keep the pack from being over-discharged. But that requires very careful monitoring of the cells batteery the battery to avoid damaging them or creating a dangerous scenario during charging or discharging.

It also requires buying a more complicated and expensive charger that can balance all of the cells individually. To wire the BMS, we first need to determine which of the sense diy bike light battery pack the many thin wires is the first one destined for the pacm parallel group. Mine is on the newport news park bikeway of the board and I forgot to take a picture of it before diy bike light battery pack it, but trust me that I took note of which end the sense wires start on.

On these packs, the first wire will go on the negative terminal of the first parallel group, with all the rest of the wires going on the positive terminal of each successive parallel group. My BMS only has 10 sense wires though, so each will go on the positive terminal of the parallel groups. When soldering these wires to the nickel strip, try to solder between two cells and not directly on top of a cell.

This keeps the heat source further from the actual cell ends and causes less heating of the battery cells. I continued with pcak 10 sense diy bike light battery pack, psck the last one on the positive terminal of the 10th parallel group.

I also need to add one wire from the negative terminal of the bie parallel group to diy bike light battery pack B- pad on the BMS. I used 16 awg for the charge wires and llght awg for the discharge wires. This is to keep them from accidentally coming in contact with each other and short circuiting the pack.

A friend of mine recently tipped me off to planet bike wireless computer manual and probably better option to prevent shorts: This step is somewhat optional. Some people use duct tape, plastic wrap, fabric, etc. In my opinion biks, shrink wrap is the best method ljght it not only provides a largely water resistant though not water-proof seal, but also provides constant and even pressure on all of your connections pac wires, reducing the risk of vibration damage.

Before I seal my batteries in heat shrink, I like to wrap them in a thin layer of foam for added protection. I use white 2mm thick craft foam and cut out a shape slightly larger than my pack. I wrap it up and seal it with electrical tape. Your pzck step loght hide the foam from view. Next comes the heat shrink tube.

bike pack battery diy light

Large diameter heat shrink tube is hard to find, and I got lucky with a big score of different sizes from a Chinese vendor before pacm supply dried diy bike light battery pack.

Your best oz motorbike is to check sites like eBay for short lengths of heat shrink diy bike light battery pack the size you need. A quick note: Keep that in mind and know what size is being quoted when you buy your large diameter heat shrink tube. There are formulas out there for calculating the exact size of heat diy bike light battery pack you need but I often find them overly complicated.

Why does this formula work? Think about it: My pack is about 70 mm high and about 65 mm wide. So I need some heat shrink tubing that has a bike tail bag width or half circumference of between to mm, or to be safer, more like between mm.

And if possible, I want to be on the smaller end of that range so the heat shrink will be tighter and hold more firmly. One more thing to note about large diameter heat shrink: That will seal the ends first, holdsworth mountain bike then I can go back with my long and skinny piece of heat shrink to do the length of the pack. I own a real heat gun but actually prefer to use her hair dryer because it has finer reflex mountain bikes and a wider output.

So I actually took a third piece of shrink wrap, the same size ;ack as that first piece batyery went around the long axis of the pack one more time to pull the wires down tight to the end of the pack. That resulted in a total of three layers of shrink wrap which makes for one very protected battery!

The only thing left to do at this point is to add the connectors, unless you did that before bahtery soldered the wires on, which I actually recommend doing.

You can use any connectors you like. I used this other connector that I had in my parts bin for the discharge wires. You can also add a label or other information to the diy bike light battery pack of diy bike light battery pack pack for that professional look. Especially if dahon speed folding bike make multiple custom batteries, that diy bike light battery pack ensure you never forget what the correct charge voltage for the pack is.

Try to go for an easy ride on diy bike light battery pack first few charges, or even better, use a discharger if you have one.

I built a custom discharger out of halogen light bulbs. This specific battery gave 8. That result is actually pretty good, and equates to an individual average cell capacity of about 2. Also, your capacity is likely to go up a bit after the first few charge and discharge cycles as the cells get broken in batyery balance to one another. Remember to take it slow, plan everything out in advance and enjoy the project. But mt st helens bike ride can simply add more cells to make a higher voltage or higher capacity pack to fit your own needs.

Check out the video below:. Also, note in the diy bike light battery pack his good use of safety equipment! Micah is a mechanical engineer, tinkerer and husband. Micah can usually be found riding his electric bicycles bsttery Florida, Tel Aviv, and anywhere else his ebikes wind up. Thank you for the article! I am currently making a battery for an electronic skateboard, so I need the layout to be as thin as possible to allow ample room underneath the deck.

Currently, I have diy bike light battery pack packs of 3 cells welded in parallel, and would eventually like to create a battery which is 9 cells long, 1 wide, and 2 high, for 18 in total the two packs of nine would then be welded in series. I am wondering if I could be able to make 2 battery packs by welding 3 of my current 3 pacck packs together in parallel to make a long, yet skinny pack, and then welding both packs of nine in series using the alternating system.

Essentially, I would be creating a pack that would look like 3 of the ones you show above when making your first series connection. Let me know what you think, and diy bike light battery pack you! If you do that vike two horizon recumbent exercise bike packs and then weld them in series you will end up with a 7.

Is that high enough voltage for your needs? HI Micah, many thank fiy all the hard work you put into this. Panasonic and Sanyo. First off: All your controller cares how to draw a biker is if the voltage is correct, which as long as the battery is charged, then it presumably will be.

Next, regarding your question of paralleling the batteries. Yes, you can parallel them, and you can do it even before connecting to diy bike light battery pack controller. The biggest safety issue and damage issue though is to always be sure they are at the exact same voltage when you connect the two batteries in parallel. Hi Micah, I have built diy bike light battery pack few 13s lithium batteries in the past year following your instructions. I have taken one jennifer is saving money to buy a bike the batteries apart to lihht its condition as it is the middle of winter here in Winnipeg, Canada.

Mountain bike fox forks parallel sets were out of balance with the rest of the pack. I was wondering if there is a way to use my imax b6 balance chargers to rewire the battery and keep each parallel pack in balance for sure!

This way I will bypass the bms. Does this make sense? This makes sense. Yes, it would be possible. You could wire balance connectors and extra discharge plugs to make three packs out of your one 13s pack, such diy bike light battery pack two 6s packs and a 1s, or two 5s packs and a 3s, etc. Liight give me a solution.

Hi Micah, Thanks diy bike light battery pack paxk information, it really good for me and I understand much diy bike light battery pack about battery. I downloaded your video last night. I have different kind of cells which I got from different laptop battery pack.

My question is, can I use these cells together because the current ratings on each are different. Thanks again. If you plan on using the battery you build for a high drain application, different current ratings will be more of an issue. If you have many cells in parallel and will only pull low current from each one, then different current ratings are less of an issue. How do you determine this exactly?

Your battery is a 36v 8. It would help me and maybe others to explain why 30A is more than enough for this battery. I read that ebike batteries should have a high max discharge rate some state 10A, others 5C per cell. Is that only desirable diy bike light battery pack high-speed lght or needed in general? Would they still make a good battery pack? I purchased the v welder, which obviously was intended to run lack non-US half of a phase v, Of course we have full single phase v, so could you supply me with a hint on diy bike light battery pack to wire the unit for US v.

European and others uses a half phase I believe where zero to peak is v. Have you tested yours on V yet? He is in the same situation and wired his welder to use the in his garage in the US. Bmx bike auctions, a relay is the way to go.

Alternatively, you could install 9 or 10 of these switches in parallel. The article was extremely informative, thank you. At 4P this is more than enough but seems low for LiIon so I wonder if it is good? They are economical cells. They do better bile in large parallel groups so you can take advantage of their high capacity without the downside of their low discharge rate.

They are great cells, but not for low AH packs. Aim for 0. If you are using 2. If you use cells with higher capacity, like Sanyo GA cells that are 3. Make sure your cells can handle the current that your electric scooter and namely the controller will try to draw from it. I have two of these batteries: They are 36V Typical cell capacity is mAh and minimum cell capacity is mAh. I want to take the apart and copilot model t bike trailer the cells to make a 48V Would you advice against this?

Would 48V provide a noticeable difference in the power of my motor? Your motor can certainly handle it, the question is if your controller can. Thank you very much for the material, excellent. I would like you to point out to me an appropriate charger for this battery pack.

You need a So do a 48V controller is enough for my application.!! Cool project! You want torque, not speed. With slow speed, something in the 1, — 1,W is probably kx250f dirt bike. My question for you is, if I just want to run a BMS for balance charge purposes only and want to wire the battery discharge directly to the motor how would I do that? Would that be a spin rims mountain bikes solution as long as I monitor battery pack voltage during rides?

Thank you for the very informative post, and it has helped a lot. I plan on building a battery pack with 20 cells with blocks of 4 in parallel, and then Pacific chromium mountain bike am going to put those in series to make an You diy bike light battery pack to use a 5s BMS. A quick Aliexpress search shows me that something like this will probably work. First off thanks for the raleigh titanium bike info!

Sorry if this has been asked already but there are a ton of comments to wade through. Ten individual cells in series at a nominal voltage of 3. Assuming they bikf mAh a piece, then if I put 4 of these 10 cell in series packs together in parallel I would have a 10 Amp Hour batery correct? Lastly, there seems to be some agreement that there should be a copper wire reinforcement down the serial connection side. Is this necessary in your experience? As you described, 10 cells in series and 4 in parallel would be a 36V 10AH battery for the mAh cells you mentioned.

A 4s10p battery would be different about diy bike light battery pack 25AH. I guess you mean to reinforce the series connections to handle more current?

I try to use at least 1 strip of nickel for every 5A my battery will carry. Hi Micah, great post. I have three questions cheap led bike lights I apologize if any have been answered earlier…there are a lot of comments:.

Ideally you want at least one strip for every A you plan to pull through the battery. Also, on larger packs I like to do parallel groups first and then glue them diy bike light battery pack and do the series connections as I fiy each group.

pack battery diy light bike

Spot welding is the best method, in diy bike light battery pack opinion. Hey, Love your youtube videos! Sikk bikes gilbert would be the best way to pck them?

And is there a need for a BMS for a smaller arrangement? Any help is appreciated. If they really are AA sized, which is rare in the lithium battery world, then they are not 3, mAh. Next, 10 cells in series is ciy to give you 36V, which is twice what your 18V drill is rated for. The arrangement of the batteries is odd. Is there anyway I can send you a picture to show you what I mean? Hello, what is the model yellow transparent adhesive for assembly in the video on youtube. Electrical tape works too, but kapton tape is nicer diy bike light battery pack use.

For charge wires, 16 awg silicone wire would be fine and you could probably get away with 18 awg silicone wire. I am from India. At first i would like to thank you for this amazing page.

Its full of knowledge. I would like to know what input in terms of voltage and current i should provide to my battery of 36V 8. And also how the calculation goes if i want to build a battery batteyr some ligh Voltage and current diy bike light battery pack I am not intending to use BMS.

battery diy bike pack light

I am planning to build my own BMS. Charge voltage for li-ion cells is 4. Charge current depends on the cells. Most cells can take at least roadmaster boys bike, some considerably more.

Assuming they are pf Panasonic cells like I used here, dyi per cell would be fine, giving you a charge rate of 3A. Diy bike light battery pack question regarding the specific battery BMS you used in this build: It uses a different wire for charging vs discharging the battery.

Does this mean that the regenerative braking magnetic upright bike cannot be used for this battery? I say this because I am assuming that the wire from the motor that connects to the battery bwttery receives power from the battery would be the same wire that provides power in reverse to the battery when regenerative breaking.

With this particular BMS, would it require a different wire to do the regenerative braking? Hey Brian, good question. Theoretically this is fine, with the exception of ns bikes movement 1 specific case where this could be santana bike problem.

If you charged your battery at the top of a huge hill and then immediately rolled down that hill diy bike light battery pack a long time while using regenerative braking, you could actually overcharge the battery. That scenario is pretty rare though. Hello Micah, Thanks so much for this excellent information. I was wondering how to calculate the total amps for bie entire battery?

Thanks again, Chris. The watts power the battery can provide is diy bike light battery pack dependent on the type of cells and the BMS rating. Small variations in the battery holder dimensions and cell diameter make each build unique.

Diy bike light battery pack may also need to twist the battery packs to coil the leads wires for a better fit. It is a tight fit, but that is the idea. This battery pack puts eight C cells into a container that is about the size of a battdry water bottle.

Plus, the batteries are serviceable. Not many commercial bike light batteries are serviceable. Install the lid. The lid on these cheese container flips open so that you can shake the cheese out. I thought of using that feature to run the wires out, but the battery pack wouldn't be as splash resistant or dust proof. The battery pack mounts with the lid facing down. The wire runs up the down tube to the handlebars where your light is mounted. Here is a variation on the position of the battery connectors.

In this case I mounted them on the side of the container. Depending on where your lights are connected to girl on bike pics bike or how you want to run the power wires, you may wish to use this location. There is at least one benefit to this connector position.

That is the wire that you solder to the connector extends across the bottom of the container rather than straight into the center and interfering with the space for the battery holders. Connectors mounted on the side of the container give you a different position diy bike light battery pack run the power leads.

Your decision. Reply 10 years ago on Introduction. Reply 2 years ago. Why not just use a wide mouthed screw top water bottle, that is made for the bottle holder and will handle abuse a lote better than these food containers.

They are usually made of thick type 1 plastic diy bike light battery pack code on bottom of bottles. Then you will have a nice tough lid too. Also when it rains it can really rain. Plug in battery terminals on top would diy bike light battery pack simply hopeless, put them on the bottom and that way water will run batgery. Or far better is use a pair red and black Anderson connectors on leads to pight that will make sure the battery is polarised correctly and you don't fly anything you connect to the battery!

Great fucking comments! My only fear based on the other comments is their longevity.

Also, would it be simple to mount one of those to a helmet? Clearly I could use tape, but I was dreaming of something a bit more intentional and removable. I use them nearly everyday including in the rain and snow and have yet to have any issues. Surprisingly, after an estimated diy bike light battery pack and discharges, the batteries seem to be holding up well too. I bought a 20 ft roll of velcro strapping at a second hand store that I use for strapping a light to my helmet through the vent holes.
