Not only will it save you room but it also cuts your weight by over 60%! The MML-1280B battery is in a group 31 case so it will fit right where your old batteries previously sat! Built with Lithium Iron Phosphate (LiFePO4) technology this battery has twice the power, a fraction of the weight, and lasts 4 times longer than a sealed lead acid battery.

Very simple plug ang play! Up to 4 batteries can be wired in series for 24v & 36v trolling motors or 48v systems.
