Aluma-Bass Posted May 6, 2015 Posted May 6, 2015 I just got a used bass boat that I swapped out trolling motor to 36v. The boat has on board 3 bank charger installed. Can I hook charger up to the 3 batteries that are in series? Or would I have to dis connect the batteries in order to charge? Quote
Super User Wayne P. Posted May 6, 2015 Super User Posted May 6, 2015 Just connect the charger leads to each battery + and - . Current flows between the positive and negative terminals on each separate battery. You do not have to disconnect the jumper wires. You do not get 36V until you complete the series connection with your trolling motor power switch. Quote
