After more than 3 month tests and try, I decide to give up on this battery.
My current problem is that when I take the battery to go ride, I have no idea if it will work or not even if it’s charged.
If I have the 4 or 3 green led light → It will work.
If I have 1 green light (stay or blinking), it won’t deliver any power to the motor. (but It can turn on the light..) → When I have this case: I have to open the battery and press the reset button or I have to wait 10 minutes for a reset and pray that it will work.
It’s currently not enough efficient for my use.
So I will stop here. (maybe come back if progress are made).
Bye.
