Risking that I ask something asked before...
DALY Smart BMS 4S 250A...
I build the 4S battery: without BMS it works fine against the 2.000W inverter.
No I connect the Daly BMS.
I followed the instructions in this manual: this manual
So the simple steps: I connect BMS B- to the batteries Minus; connected the sensing cable (black on battery Minus, first red cable etc...): I measured on the connector of the sensing cable and got nicely 3.3V, 6,6V, 9.9 and 13,17V (except for the last one, the other are rounded, cells are perfectly balanced).
then I connected sensing cable (actually correct word?) and I expected 13,7V on the P- of the BMS.
But I got something like 9,62V.
I had ordered 3 same BMSes: checked on number 2: same issue (with the same wire).
What is going wrong here?
What is the most likely issue here?
I am trying to contact Daly as well.
