Excellent charger for the customer that stores their boat in a storage lot or a guy on vacation that doesn't have access to plug in an onboard charger. It will recharge the trolling motor battery any time the engine is running. A must have for the serious fisherman.

Brian Burkard (Rotonda West, US)
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.
