I’ve opened the dead batteries from @ridiculed and came to the conclusion, that the stock BMS doesn’t even balance with a few other battery builders.
It seems to fail somewhat regularly from what I’ve seen here.
@xsynatic I advised @Kev for a discharge BMS because there will be no under discharge protection.
For us DIYer’s with vescs it’s not a problem, because the vesc protects the battery from being drained too much. But I don’t know how a shitty lingyi handles this. And I don’t expect from a regular non tech guy to monitor his battery pretty much every time he goes riding.
I will try to fit in a charge only llt for one of the batteries of my friend and have already told him of the risks. He now has to check battery voltage when riding, so he won’t drain the battery past it’s limit.
