So, this is the description.
My old charger died recently and I borrowed charger from my friend to recharge battery a little bit before new charger come.
I disconnected main fuse because I have DC-DC converter which use some power all the time. Then, my son came and pushed throttle, wheel rotated few times and everything was dead after that.
New charger came yesterday, everything works while it's connected but there is no power at all after I disconnect it. I doubt on BMS but I have no enough experience to be sure and that is the reason why I ask you guys for help. When ignition is on and charger disconnected voltage drops rapidly and everything is dead after maybe two seconds. Led light on charger is always green and fan doesn't work at all so I think it doesn't charge actually, just maintain voltage while it is connected.
What I wanted to ask is if there is any way to "reset" BMS if it's some kind fooled because of what happened before. System is LiFePO4, 20S.
Thank you very much for your answers and suggestions, with best regards.
