I have a 16s 48v sinopoly 90ah bank. All cells were close on voltage within a few hundredths when assembling. I have ensured all leads are connected properly after having a few wrong at first The battery bank voltage and B- are the same. P- lead is showing 17.8v though. Resistance between p- and b- is not able to zero. I have not dared connect to charger or inverter in current state. I tried shorting out the b- p- as shown on other feeds but nothing yet. I don’t have another 48v BMS to test against as I had only built 12v batteries before. Any options before I buy another BMS to resolve the issue?
