Hi everyone,
My setup:
BMS: DALY BMS 4S 12V 120A
Cells: 277ah ETC
My issue:
When multimeter connected at P- on BMS and main positive it reads a very low voltage: around 8.36v (see pictures)
Although when multimeter connected directly on the main positive and main negative it reads 13.36v...
No I didn't, I put it once the pack was fully charger but didn't add the PSU once BMS was connected. I will try
Thanks, I didn't know that. Out of curiosity, why is that?
