Lithium Pros M75-36 38.4V 75Ah LiFePO4 Bluetooth Marine Trolling Battery

The Lithium Pros M75-36 (M3275-36) is a 38.4V 75Ah Lithium Iron Phosphate (LiFePO4) deep-cycle trolling battery engineered to replace three traditional Group 31 marine AGM batteries with a single, lightweight unit. Designed for freshwater and saltwater tournament anglers running 36V trolling motors, this battery delivers all-day power without the bulk and weight of conventional lead-acid setups.

Key Features:

• 38.4V / 75Ah (2,850 Wh) of consistent, high-output lithium power
• 173 reserve minutes of usable energy — enough for a full day of trolling under normal conditions
• BCI Group GC12 footprint — same base dimensions as a Group 31 battery (plus approximately 2" in height) for easy drop-in installation in most marine battery trays
• Bluetooth connectivity — monitor State of Charge, time remaining, voltage, amperage, and temperature via the free LP Battery View App (iOS and Android)
• Internal Battery Management System (BMS) — auto-balances cells and protects against over-temperature, over-voltage, under-voltage, over-current, and short-circuit conditions
• 96% charge efficiency vs. approximately 75% for lead-acid batteries
• Weighs approximately 42 lbs — saving over 180 lbs compared to three equivalent Group 31 AGM batteries
• Compatible with optional on-board DC charger (sold separately) to recharge from the outboard engine's charging system
• Also cross-referenced as: M3275-36

Note: A 38.4V LiFePO4-compatible battery charger is required for proper charging. This battery is not compatible with standard 36V lead-acid chargers.

Whether you're a weekend angler or a competitive tournament fisherman, the Lithium Pros M75-36 delivers the reliability, weight savings, and smart monitoring features needed to maximize your time on the water.
