Ignition Protection

The essential boat upgrade that allows you to charge your 24V trolling motor battery from your engine's alternator. While on the water, your alternator's excess power redistributes so you get an extra boost, and better battery life. Our marine charger is the perfect solution for charging your trolling motor or aux batteries. With state of the art technology, the DC-DC charger applies on-demand charging voltage to your batteries so they only receive the charging current they need to replace energy that has been consumed. This smart charging system also works to ensure your cranking battery voltage will not fall below 12.5V, only transferring charge when your starting battery reaches 13.3V making it a safe and reliable way to keep your trolling motor or aux batteries charged and ready to go.

    This charger is great

    I decided to give this a try and boy I'm glad I did. Running from spot to spot, it tops off my 24v battery and after a day of fishing, its at 100 percent when I get to the ramp. I never have to use the plug in charger anymore.
