I have a hailong style battery with a hp16sa BMS.
Few weeks ago it shut down and would not power my TSDZ2. I finally sat down and opened it up.
Voltage on battery output is 45v which seems okay but i assume its below the TSDZ2 cut-off.
But the problem is battery wont charge.
I have measured the cell groups and most a 3,6 except two which are at 3,5. I assume .1v difference is okay? Or could this be the problem causing the BMS to lock?
Another weird thing is; when i measure from the battery pack directly, the voltage is 48v. But if i measure from the output on the BMS its only 45v.
Is there a way i can check if the BMS charges okay? Or is the above symptons signs its just dead?
