SF Big Dog Posted September 8, 2010 Report Share Posted September 8, 2010 I have a 3-bank charger on my boat that charges all 3 batteries when the boat is in the garage and plugged in. If I understand correctly ... When the big motor is running on the water, it charges the cranking battery but NOT the trolling motor batteries. Does anyone make a charger ... that when the big motor is running, it will charge the trolling motor batteries ONLY ? Rich Link to comment Share on other sites More sharing options...

trackertxw175 Posted September 8, 2010 Report Share Posted September 8, 2010 an isolator may be an option. they are used on motorhomes and in effect they allow the charging of the cranking and deep cycle while running engine but prevent cranking batt from being discharged while deep cycle batt is in use.

BassinHomer Posted September 8, 2010 Report Share Posted September 8, 2010 I just hooked my 12v 40lb thrust bill dance trolling motor up to the cranking battery works like a charm, I'd love to have more power though Link to comment Share on other sites More sharing options...
