I think a standard single stage charger will work fine. In fact that is the suggestion I got from ProMariner. The problem I'm having is that my charger senses battery voltage and has multiple charging stages. So both the VSR and the charger are sensing voltage and trying to react accordingly, and in the end they screw each other up.

You might need to get one of these then

Dave at Earmark sent me this link. It simply cuts the VSR out of the equation while charging.Malo <--- Means--Evil or Mean One. This explains a lot.

When the BEP switch is 'off' the VSR is still in the circuit between the two batteries and closed when the voltage is high. So now a dual-bank charger cannot run independent programs although the two banks have different chmistry if for no other reason than they're used very differently.
Many ACR/VSRs have an ignition trigger, some combine and some separate depending on the intentions of the manufacturer. For those that separate this would consititute a small but continuous current draw while in storage. Not a good option.
On those ACR/VSRs that will open once the ground is cut, the manufacturer discourages this. I'm speculating, but I suspect that while there is no potential harm to the solenoid, the solid state electronics are designed to have a ground first and last in order to maintain their programming. Not sure how sophisticated the sensing circuits are but it seems logical.
Dual-Sensing ACR/VSRs versus priority charging versions would require a manual disconnect on both banks in order to eliminate the current sensing draw which disrupts the charger's ability to precisely profile both banks.
There are numerous other layers and frequently overlooked considerations in how you utilize and integrate an ACR/VSR into the rest of the charging system. There is no perfect charging system and single prescription that best fits every boat or every boater.
We support the SurePower product and upon gaining a clear understanding of your unique system, we package a comprehensive solution. It comes with clear instructions and illustrations. And, if something becomes problematic down the road we can provide diagnostic assistance which is even harder to get than the initial manufacturer support.
