The M Series from Lithium Pros brings advanced LiFePO4 performance to serious anglers who refuse to let weather shorten a day on the water. Each lithium iron phosphate pack delivers the high cycle life and steady voltage expected from premium lithium-ion technology while adding exclusive cold-weather functionality. Whether you fish bass tournaments in Wisconsin or chase redfish on the Gulf Coast, this marine battery keeps electronics, pumps, and your trolling motor running strong all day.
Marine-Ready Construction
Every M Series boat battery is assembled in the USA with EV-grade cells that pass IEC 62133 safety testing. The rigid case meets IP67 for water and spray resistance, and internal supports absorb vibration from rough chop. ABYC E-13 compliance ensures seamless integration with existing marine wiring so installation is straightforward for pros and weekend boaters alike.
Unique Heating Technology
Cold mornings often limit charging in conventional lithium packs, but the M Series solves that problem. Plug in a charger and the built-in heating pads automatically warm the cells first, then switch to normal charging once they reach a safe temperature. Need faster turnaround before sunrise? Use the Lithium Pros app to activate Auto Heat, draw a small amount of energy from the pack, and set the minimum temperature like a thermostat. By the time you reach the ramp, the battery is ready for rapid charging on the run.
Designed by Lithium Pros
Our engineering team controls firmware, testing, and continuous improvement while searching the world for the best materials. Final assembly and quality verification take place in Tennessee, ensuring every pack meets strict performance standards before it ships.
Who It Is For
Choose the M Series if you fish cold spring tournaments, store your boat outdoors, or simply want a future-proof marine battery that withstands extreme conditions. It suits bass boats, bay boats, walleye boats, pontoon boats, and kayak rigs where weight savings, quick charging, and dependable power are priorities. Dealers appreciate the transferable warranty that boosts resale value, but direct buyers gain the same peace of mind.
What You Gain
Switching from lead acid to a LiFePO4 M Series battery cuts weight by up to 80 percent, delivers longer run time for trolling motors, and eliminates messy maintenance. Faster charging means you spend more time fishing and less time waiting and checking the charger.
