I need some help with my BMS. I have a 10s setup and this afternoon when I tried to charge my skateboard, the green light on my charger indicating it is not plugged in or fully charge would not change to red indicating it is charging. I check the voltage at the charger and the charge port of my skateboard. the charger was good as it read 42v however the charge port voltage is strange as it only reads about 33v while my battery total is measuring as approximately 37v. I have a feeling it is my BMS but it was charging perfectly find last night. please help!
I can post pictures and provide more info if necessary. In addition, I disconnected my balance leads and measured the voltages for each battery. Each measures as expected all totaling approximately 37v. the reason for the battery total being this is because my battery is approximately at 50% charge right now.
