You sure it’s broken?
Yes, the volt on the battery is 39 volt when i check the volt direct to the battery.
But when i check the volt on B- and + on the battery its shows 1,4 volt. I did som stupid shit when i was installing new charging, stupid to install +to - and -to +. And that made it fucked. So it would not charge only balance
What’s the error code it’s giving you?
Undervoltage protection. The problem is that it would not charge, c- and Battery + dont show the right Voltage. The votege on battery is 38 volt without BMS, but with BMS 1,4 volts… Nottingham wrong comes on the app
I would check the voltages on each of the balance terminals first, any lack of connection at that point would give this type of problem.
Could be just a balance wire issue
I firedel it. So battery is safe now.
