Are you looking for a lightweight battery to power your 12V electronics or trolling motor? Well look no further this is it! Weighing in at only 20lbs. Not only will it save you room but it also cuts your weight by over 60%! The MML-1280B battery is in a group 24 case for easy installation.

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