Hey all. How do you t/s if battery issue is BMS, ESC, or a the battery itself? When I get a voltage reading it is between 36v and 42v.
Here is the long story: Picked up an Acton 2 to tinker with. I am having an problem with the battery charging. The charger shows green like the battery is charged—but it immediately loses power when I disconnect. I pressed on the battery pack and got the charge light to go red for a while. Then it went green. Got about 400 yards and then it died. Then the press trick did not work. While taking voltage readings I unplugged the pack from ESC when I plugged it back in there was a little spark and it started charging. ? This time I ran the board and then I plugged it In—went straight to green. Tried the same trick—didn’t work this time. I am stumped!
