@ARetardedPillow did you ever figure this out?
I have a d140 that is about 30 cycles old. It was plugged into @torqueboards 4A charger for the second time and I believe something let go. I fell asleep with it plugged in/charging and when I awoke it was less than 50V. Thought it was weird and went to check if it was plugged in. Light was green but voltage was down to below 49V.
I unplugged the bms and confirmed that all p-groups were charged to the same value, and the value is equal to the voltage measured through the charge port. I confirmed that there is continuity on the charge port + and - . Also have confirmed the ground is good for the BMS. I have also tried a second 1.5A charger.
Is there anything else that I could check or measure to confirm what went wrong?
