The Trollbridge24® Combiner allows you to charge your 24 volt trolling motor battery from the 12 volt alternator on your main engine or trailer hook-up. It works by automatically putting two 12 volt batteries in series when you need to run the trolling motor and in parallel for charging. It is bi-directional so when not trolling, the trolling booster battery backs up your starting or house battery.
Minn Kota makes a something like this?
My cousin boat has a switch like this and hasn't had an issue.
Just looking for opinions on people using something like this product or another one brand.
Good/Bag and Ugly info wanted.
