The Trollbridge 36 allows you to charge your 36-Volt trolling motor batteries from the 12-Volt alternator on your main engine, from your trailer hookup, or from any single output 12-Volt battery charger. It works automatically by connecting the three (3) 12-Volt trolling motor batteries in series for trolling motor mode and connecting them in parallel for charging mode.
The Trollbridge 36 contains a built-in Combiner that isolates the starting battery from discharge. Additionally, the Trollbridge 36 can be configured to work with Lithium batteries or standard AGM/Lead-Acid batteries.
