Input welcome.
Have an overkill 8s 100 amp BMS that reads cell 1 and 2 as extremely low, but tests fine with a multimeter. I’ve replaced the ring terminals that measure them and same readings.
This was just installed in my RV but had been used two months ago to pre charge for a top balance two battery packs with no issues.
Tomorrow’s troubleshooting will be set up a second of the same BMS, brand new, for the second battery. If that works, swapping BMS and cables will be the next step.
Edit: User error. Did not have negative battery cable hooked up.
