36V 50Ah Trolling Battery Bluetooth | MML-3650BT

Lightweight. Powerful. Smart.

The MML-3650BT is the ultimate power upgrade for serious anglers and outdoor enthusiasts. Designed for 36V trolling motors, this Bluetooth-enabled lithium battery lets you monitor your charge status directly from your smartphone—no guessing, just real-time insights.

Weighing just 34 lbs, this battery replaces three 12V lead-acid or gel marine batteries, cutting down your load by over 150 lbs. Housed in a standard Group 31 case, it's a direct drop-in replacement—no special adjustments needed.

Built with advanced Lithium Iron Phosphate (LiFePO4) technology, it offers twice the power, a fraction of the weight, and a lifespan of 4000+ cycles, making it a high-efficiency, long-term solution.
