I currently have two 100Ah SOK batteries in a parallel string, with all exactly equal length cables. The second battery positive post has a class T 300A fuse, then is connected to a Lynx Power In busbar adapted to accept MEGA fuses. I have a QWORK shunt attached to the negative post (between second battery and Lynx Power In).
The issue so far (after one season) is the Bluetooth BMS readings from each individual battery vary wildly as though not balanced. I have COMPLETELY discharged each battery separately to BMS cutoff... then recharged completely. After a while, they're out of whack again. However, the QWORK monitor will display 100%.
I'm preparing to add an additional (3rd) matching SOK 100Ah battery. So...
Would rewiring the battery bank to a separate bus make any difference? As in... instead of cabling the batteries TOGETHER in a parallel "string", run equal length cables from each individual battery to positive and negative busbars? Then a single run from the busbars to the Lynx Power In.
Question is... would adding this additional busbar between the battery bank and Lynx Power In do anything to help keep the batteries in balance? Or a waste of time? Suggestions?
