[RE-wrenches] KiloVault Issues

[Jay]

I’m wondering if the batteries are out of balance. You might need to charge 1 set alone or even individually to get them full and calibrated. 

I had someone with a different kilovault have similar issues which when we charged them individually took care of the problem. And guessing it will come back at some point. 

The other thing I just remembered is that there are balancers from a few companies that I’d recommend ( so does kilovault). 

Kilovault and victron are the two that come to mind but are probably others.
