HOW TO MAKE A BONKERS E-BIKE BATTERY... ON A BUDGET!!!

[@MainelyElectrons]

I went the Andy Kirby route for my first build and used power tool batteries, Milwaukee specifically. Their high output batteries can do a little over 1500w each and charge up to 20.1v. 3x M18 6AH batteries in series gets me a 60.3v pack. If you have the space for 2 strings of 3 batteries it can do 3kw continuous without any issue. And charging is way faster than a standard 52v 13AH, even with the quicker 3A charger. Considering my 36/48v controller only as 61v capacitors I’m maxed out in that kit. It also saves a bunch of $ since i can just used two M18’s for my wife’s ebike. The real downside is the extra space taken up by the casing of the packs, but they sure are rugged so youre less likely to have a fire after a crash.

[@LITTLEEXPERIMENTCHANNEL1]

This is very accurate, im a RC enthusiast and I use all the way up to 6S lipo. You can dump extremely high current without significant damage or heat provided you don't over discharge them just like lithium iron. They do explode though if they are impacted heavily. Never charge unattended...... ever!

[@THEG12EG]

Use a lipo bag when charging

[@petesmith8436]

3 makita 18v 6 ah batterys, 250w hub, 30+ mph, i made a rectangle box you just slot into and fittted to bottle rack bolts. put a low voltage circuit in else you,ll kill em, pcb on ebays for like 5 quid, i set it to 45v and it cuts out. plus easy to charge on makita charger. these are the best batterys ive used so far, they sag the least and really give you power till the end.

[@wavestherules558]

If you want i can show you what i have done to wire my batteries in to my latest BMS You will need a "6s JST-XH Parallel Balance Lead Harness" cut three off with as much lead as you can then solder these to the balance leads (in sequence) of your BMS. I can do you a little vid . Been making my own mid drives since 2012.

[@h82fail]

Most BMS are sold for Li-ion and LiFePo. Curious what high current BMS you are using. Building a high power eMTB conversion and torn between building a pack for the frame and just using lipos in a backpack but I would feel much better with a BMS watching the balance leads.

[@chrisjamess2241]

Aup mate can this be done with scooter batteries I have two 36v batteries could I pear them and make 72v 🧐🤔🙈🦚

[@sleepingbearffg5008]

I flew drones. 15pacs a day. For years. Best system by far. If one pac fails dont have to replace whole batery. There made to drain.. charger's show each cell condition. And charge faster. Good choice of charger brother 👊👊💪💪 your friends giving you good advice. 👊👊💪💪 if ever see a cell not balancing right? Through away. It will get worse and explode one day charging or full throttle for to long.. and trust me. Scary shit! Always charge outside!!

Nice vidéo Dude,yes lipos are fucking dangerous,never charge them in the house unsupervised...and get à smoke detector..Regret that lipos have little Mah capacity but for amps its unbeatable...can't wait to see your monster build..well done on the safety aspect..

[@ecocentrichomestead6783]

WRT battery fires, I thought about something earlier today: Batteries are the most expensive part of the project. Therefore, people try to get the most they can using the least batteries. This results in maximum discharge over an extended period of time. The battery eventually overheats and goes into thermal runaway. Maximum discharge should only be used in short bursts.

[@Simplyflyit]

I have heard of this idea before...lol... good to see you on the wild side

[@robp4564]

Too many new ideas, my mind's going overdrive now, keep it up!

[@mrcleanisin]

You did not mention what voltage motor you are using.

[@DescartesRenegade]

I have a few 60v 4Ag greenworks batteries that i use for various ride-on projects. These things give me low range but they make the thing go FAST. Its quite the fun.

[@DudeStuff]

Run 3 or 4 together for 60v 12ah wouldn't be bad

[@DescartesRenegade]

@@DudeStuff wish I could. These things are massive for the little capacity they hold. It's only a 15s2p battery but the overall size takes up the room of a 13s6p pack. Nevertheless, these tool batteries are quick and easy to use if I want to push the controller to its limits.

[@MrFruitycakes]

hi hi steve. suggest you pop those big bad boys in a lipo fire-proof bag or 'bat-box' when you have them in your backpack!!

Hey thanks for that Steve,that’s given me some ideas about a project I have in mind,good man!👍👌

[@dazaro3]

Great fun but you got to be careful because a lot of controllers have 63 volt capacitors and just going slightly above their maximum can blow them.

[@DikTrom]

always make sure only one wire is exposed and is impossible to get a shock basically, use wago clips to always isolate a wire ,also when it does not need a connection. I think I have to make a video myself to show how to work safe. I see a lot of naive electro "tips", these vids are the real danger. Eg 5:41 he does not connect but that is what I mean, first top these wires with wago's and you can safely connect it, and then one by one connect them to the other battery.

Be careful of over discharge as lipos do not have over discharge protection. You have to set minimum voltage in the controller.

is there some kind of reverse resistor switch that CUTS off the circuit if the voltage drops to a degree ?so it can be a inline resistor on the cable itself

Now you have a lot of Amps, and no AH. When you have full charged you become 6A for 1 hour, ore 600A for 10seconds .... the biggesst sabvoton is 200A this you becomes for 30seconds ... 🤔

[@DudeStuff]

@@72V_AlphaBike Thanks for the comment! I’ve actually used a 6Ah LiPo battery pack on a 9000W setup running 100-150A, and I managed to get around 6-7 miles out of it, so the idea of it only lasting a few seconds doesn’t add up. Even at high power, you’d typically see a few minutes of runtime unless there’s inefficiency or something seriously wrong with the setup. Of course, running packs in parallel can boost capacity, but even a single 6Ah pack should perform better than what you’re describing. I ran this pack for several miles riding on a video

[@72V_AlphaBike]

@DudeStuff Thanks for the correct position. It was just a short theoretical calculation. Of course we rarely drive at full speed, so you can probably get further than I described. I thought your idea of ​​the battery was good, but unfortunately it wasn't suitable for me.

@@RetroMods yea if I was stilling running those batteries in series they’d all be toast. I didn’t even have close to enough amps to keep it going.
