It is a 1A Daly Smart Active Balancer.(Seperate balancer.)
Battery : 51.2V 280Ah
BMS : DALY Smart BMS
Everything is reading correctly everywhere. Cell voltages are being read correctly by the bms and the balancer as well.
One cell no.7 is quite above other cells and hitting high voltage cutoff when charging.
Lets say it hit 3.55V and i turned off charging. It drops a bit to 3.5V
Pack voltage : 53.5V
And then the Balancer balance switch turned on. (I set start voltage to 3.4V)
The moment it turns on cell no.7 will jump from 3.500V to 3.56V (sometimes about 100mV)
And pack voltage rise 0.5V (from 53.5 to 54V)
This is all only READINGS on the Active Balancer's Bluetooth app(or pc app Ive tried both and same results.)
All voltages on connectors, inverter + and - , bms + and - all show correctly, BMS's own bluetooth app also show correct voltages.
The balancer is the only one showing higher voltages.)
NOTE : Balancer shows correct voltage when NOT balancing.
I have tried 3 of these balancers now.(all brand new) and all 3 are making the same behavior.
Any idea why that is happening?
