I have a system that conforms to the Victron recommended schematic for two battery protects. One to isolate the charging current, one to isolate the discharge.
However, for redundancy, I have two of these systems in parallel, and when the battery banks are out of balance, there is a potential for a small reverse current to flow ~5 amps, quickly settling down to <1Amp, then zero between the batteries until they balance. This happens until the battery banks balance between the two, then it stops, and the voltage difference we're talking is also small, <1V reverse bias across the battery protect.
There is no way to prevent this (aside from only using one battery bank at a time). Should I be worried about ~5amps flowing reverse through the battery protect for a short amount of time?
Also, when the battery protect is off, is it also preventing current in the reverse direction? Or does this device only provide isolation in forward bias?
From an engineer's point of view, I wonder why the battery protect datasheet is so lacking of information.
