rex update to latest version if not already, perform a reset, shutdown all of them, remove all cables, connect them together. start only SBV. batteries should start automatically. charge level shoud be similar.
israndy What happens if you hook a battery to your SBV that is discharged and your SBV is full? Do they balance? Does the one battery charge the other? What if you hook a dead battery to a full battery w/o an SBV involved?
