Epoch Lithium Trolling Motor Batteryare a great battery for trolling motors and electronics on boats, and they are also a great deep cycle battery for camping, RV's and golf carts. The Epoch lithium deep cycle battery I am using is 24v, but Epoch makes a complete line of 12v and even 36v batteries. The deep cycle marine batteries are a great choice to power you trolling motor and also you marine electronics.
