The essential boat upgrade that allows you to charge your 36V trolling motor battery from your engines alternator on the go! While underway, your alternators excess power redistributes from your starting battery so you get an extra boost, and better battery life for your trolling motor.

How it works: With state of the art technology, the ABYSS On-Board Alternator Charger applies 10A of on-demand charging voltage to your 36V battery so it only receives the charging current it needs to replace energy that has been consumed. This smart charging system also works to ensure your cranking battery voltage will not fall below 13.3V, making it a safe and reliable way to keep your trolling motor or aux batteries charged and ready to go.
