    Charging scooter packs in parallel

    I have 3X scooter battery packs (36V) that I will wire in parallel to increase capacity and amp draw. Each of these 3 pack has it's own BMS, and also seperate charging port. Will I damage the packs if I charge from one of the charging port while they are still connected in parallel? Would the...

    14s10p non welding DIY battery

    if your previous battery last you 6 years, I would go get it again, and if you want to increase your range, buy 2X of it. From personal experience, building DIY battery no-weld system is costly, and in the long run too much work to take care of. May I ask what battery did you get from your old...

    Hi Everyone, I managed to get an ebike off CL, but it has a bad controller (I tested it with another controller from my other ebike and it works). So I need a new controller, unfortunately everything is in Chinese, and I can't figure out what I need. I know that it's 250W and 36V. But 250W...

    I got some knock off imax b6AC off ebay, and I was wondering if there's a higher current charger out there, this thing is capped off at 6A, even if I'm only charger at 1S.

    problematic battery configuration?

    I'm working with some 3.7V 18650, and I have to ask this question. A lot of time people would built a 9-10S pack for 36V. However my cheap old balance charger can only do 6S max. to get a 9-10S i would have to pay more (I payed 25~ per 80W balance charger). Can I do 3X 12V pack? say 3-4S, and...

    18650 pack build using plastic battery holders

    the holders are expensive IMO... I saw them but scrape the idea, I wanted a pack with tons of battery, and this will cost too much. I've seen some design using them and it's really nice.

    Need help with DIY battery pack.

    Is there a cheap source for premade battery? If I was to DIY battery packs, I'm having issues with an easy method to bulk test, have anyone ever discharge these battery using resistor? those are cheap enough (a 10W is less than 50 cents), I can discharge and use a hobby charger to recharge it...

    Need help with DIY battery pack.

    My line of thought is that I don't want to deal with balance charging, and charging individual packs isn't that bad (easier to monitor too) if I'm doing an ebike, I'm probably going to sit around 36V, which is roughly 10 packs of batteries in parallel wire in a series. I'm actually working on...
