Renogy 200amp lithium battery balance

[electrospidercrab]

I have 2 x200 Renogy Lithium batteries in my camper hooked through NDS PowerService unit, mainly charged with Solar, I notice a big difference in %full, at the moment 1 reads 62% and the other 42%. Question why are they not balanced the same or similar?

 

[Dellmassive]

are they directly connected to each other?

do all the power feeds come from a common busbar?

are the cables the same length from the charge source?

all so to the above.

then it will be BMS drift.

YES TO ALL YOUR?, SO BMS DRIFT? Is that a problem, is it fixable. Thanks

 

[Dellmassive]

No it's not a problem.

You can reset by fully charging the battery bank.

Easy fix.....
