BMS overdischarge triggering ? #416

Description

I'm making a drift trike with a classical 3 wire ebike throttle as an input. The board shuts down without bipping when accelerating to fast, and cannot be powered again using the power button. I need to unplug and replug the battery to be able to power up the board again. I assume that the over discharge protection of the BMS is being triggered. Am I right ?

Is limiting the current more my only option ?

But I didn't change the default 15 A current limit setting. If I'm right, How can it be that the stock hoverboard BMS current limit is lower than 15 amps ?

I am having the same problem with a hoverboard that I haven't reflashed. Is there a way to prevent the overdischarge protection to trigger or should I just use a more powerful battery? Also would connecting two hoverboard batteries together in parallel work?

the thing that worked for me was changing the battery with another one from an other hoverboard

I already tried using a battery from another hoverboard but I got the same problem. I guess it depends on the quality of the manufacturer.
