Have had an interesting BMS issue. I ordered 8 280 ah cells and 2 BMS from Deligreen. everything arrived great shape. The BMS is actually Daly 200a discharge 100 amp charge.
1 of the BMS would bring all 4 of its cells to correct charge as set in BMS App
#2 BMS would bring all 4 up to 85 % of charge but then only cell 4 would come to the set value the other 3 would stop at at 80 to 85% with no balancing.
switched cells around and swapped BMS but the one BMS was bad.
Dealt with April Cao at Deligreen they asked me to do some tests take pics of app settings. It has all taken a few weeks but The BMS is being replaced.
The support effort has been great!
They didn't ask me to anything more than a thorough check.
Good Vendor Follow up
