36v 40Ah Lithium Trolling Battery

36v 40Ah Lithium Trolling Battery . Are you looking for a lightweight battery to power your 36V trolling motor? Well look no further this is it! Weighing in at only 31 lbs, this ONE battery can replace THREE regular marine gel/acid batteries! Not only will it save you room but it also shaves off an estimated 150lbs or more! The MML-3640N battery is in a group 31 case so it will fit right where your old batteries previously sat!

The MML-3640N does not have the external meter nor is it bluetooth. This results in a slightly lower price for our customers! If you’re running the power pole charge system then you will be able to view this batteries state of charge through its app. Otherwise just treat it like regular batteries! Charge them then fish hard!

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. If you’re fishing heavy current and needing extra capacity or just simply want the extra juice another 36v battery can be wired in parallel (positive to positive & negative to negative) to increase the amp hour capacity to 80Ah! Installation is as easy as attaching the main positive of the trolling motor to the positive post of the battery and the main negative of the trolling motor to the negative post of the battery. Very simple plug ang play!
