Hopefully one of the experts around here can help me out. I bought a ProMariner dual bank charger so I could a.) recharge the batteries fully after a day on the water and b.) maintain the batteries (float) during winter storage. However it doesn't like the way my batteries are configured and won't charge.

After several discussions with ProMariner support they told me this type of charger isn't compatible with voltage sensing relays (VSR). Is that really true or does it just take a little more creative wiring?
