Hi All,
Just installed 4 smart 200ah lithium, with new multi’s (3) 12/3000/120 12v, cerbo, bms etc. Batteries are all fused individual and connected to busbar’s.
Charge disconnect is done via Mastervolt alpha pro, via bms fort the multi’s, load disconnect is organized.
The batteries are new. When charging it worked for about 3 hours with about +/-170 amps (set as limit). After a while the red led on bms started to go on and off and the chargers go up and down as well. Is this a malfunction or are the cells being balanced? the red led says hi voltage or temperature. This is not the case when I check the individual batteries with bluetooth. Some cell imbalance is there in the individual cells.
Is it normal or not?
Thx!
