if you use a 2 bank charger you can charge the starting battery and the trolling batteries,you would hook the charger to the trolling batteries as followed battery A pos to charger pos and battery B to neg of charger, this is with the batteries wired parallel the charger looks at them as 1 big 12volt battery in this configuration...if you use a 3 bank charger you will have to disconnect the batteries parallel wiring in order to charge the 2 batteries, its not like a 24 volt system where you can hook both batteries to 2 separate charger leads!!!!and the charge time is not that much longer I have used this type of configuration for years until I went to a 24 volt system!!!
