Hoverboard battery charging for ebike

[shawnbfromjersey]

I'm putting two hoverboard batteries on an ebike. How do I charge them? I was thinking about buying the three pin universal adapter and cutting off the three pin and replace with xt60 connector.

I would try electricity. That works for my batteries. I think some of the more seasoned members might be able to guess what your setup is and provide more detailed guidance.

All the hoverboard batteries I have seen are 36V lithium ion 18650 cells with a single pair of leads. These are used for both charging and discharging.

If I were making a charging setup for hoverboard batteries, I'd use an adapter cord from XLR (or whatever plug is on the easiest charger to get) to XT60. That way neither replacement battery packs nor replacement chargers will require modification.

Mind you, 2 amps each is about the fastest you should consider charging those little packs. I would get however many 2A chargers you need, and charge the packs separately until full. That way you know no single pack is getting charged too fast.

Only link them in parallel when they're fully charged and sitting at the same voltage.

P.S. -

2 hoverboard packs is not very much juice for an e-bike. If your controller takes more than about 17A at full load, you'll be driving the batteries to their limit or beyond. They will perform poorly and wear out quickly.

Ya, but six packs, made with Sanyo cells, in 72v configuration could be pretty entertaining. Crappy Chinese cells, not so much.

True that. I reckon that the 2200mAh cells in these packs, good or crappy, are optimized for high discharge rate rather than capacity. (Like cordless tool cells?)

But surely maintaining cell health and abiding by the limitations of the connecting tabs means not running them at or near the exaggerated maximum specs. The cheapest hoverboard packs on eBay right now claim a continuous rate of 20A (4.5C) and a max rate of 30A (7C)! That seems like a recipe for problems.

I can buy the charging port cord on Amazon for hoverboards and put a xt60 connector on it. Use the regular hoverboard charger to charge
Thanx
