Charging without BMS?

So when I was assembling my battery I accidentaly made a big solder blob of a joint, resulting in a short in my BMS. It is useless now, but it is the last part I need in my build that has been going on for over a month. So I was wondering if it is possible to charge without the bms? Just for about 2-3 cycles until my BMS arrives in about 2-3 weeks.

If it is possible, would work if I just hook up the chargeport to the negative and positive terminal of the battery?


It depends, but 2-3 cycles should be fine. Just dont ride to your cutoff voltage, and if you can, dont charge to full voltage. Shoot for about 4.1v per cell.

Thanks for the advice. Would the method of just attaching the chargeport to the terminals of the battery work?

This method will work. I have run my 10s 4p 30q battery for, at least, a year without a BMS without an issue. Not that I advocate this. I have other boards with BMS’s.


Same here, but it’s always good to check every week to see if they are indeed balanced

Quality cells in a pack built right (so all cells have a evenly distributed current) doesn’t go out of balance quickly

Thank you. This is only a temporary solution until I get my BMS from China. But the itch to ride my build is so damn high that I simply cannot wait for it to arrive.
