Location: Michigan | I can't believe I didn't know these existed. A freind bought this to my attention. I just talked to Dual Pro, and it really does sound like a sweet deal. Basically you connect the unit between the start battery and the TM batteries.
As you run the big motor down the lake, the charge that would normally go back in to the start battery "spills over" in to this unit, and then to the TM batteries. Said to extend TM battery life within a normal day by 30% and reduce the amount of time needed to recharge the batteries after a day on the water. They seem pretty reasonable in their price as well.

Anyone have any first hand experience?
