So I think I want to install a ProSport 20 battery charger which is a dual bank 20 amp charger. However, I was thinking that since it's not that much more for the 20 Plus, which is a three bank charger, that I should just get that instead even though I only have two batteries. This way, if I decide to add a third battery in the future, I won't have to upgrade the charger.

So, my question is, does anyone know for sure if the 20 Plus will work with just two batteries? I tried calling ProMariner but all I get is a recording.

Thx.
