The Combiner 100 is a voltage-sensing relay (13 volts) which connects two batteries together when either is receiving a charge.When the charging ceases, the relay opens so that each battery operates independently.UNLIMITED WARRANTYYou never have to worry about switching to "BOTH" when your engine is running and forgetting to switch back to save your starting battery from discharge when you stop.

Great product.. works as advertised
Does charge trolling motor battery in addition to main battery. However, you will need to run your engine a lot for the trolling motor battery to be fully charged, particularly when trolling a lot... overall happy with the product, certainly prevents battery from full discharge during an extended outings.
