Lithium Pros L22-12 12V 22Ah LiFePO4 Marine Lithium Battery

The Lithium Pros L22-12 is a 12V 22Ah Lithium Iron Phosphate (LiFePO4) deep-cycle battery engineered for marine, trolling motor, and powersports applications. Part of Lithium Pros' popular L-Series lineup, this battery is built with LiFePO4 cells tested to the UL1642 standard and is specifically recommended for inductive motor loads including trolling motors, electric motors, and motive power systems.

Key Features:

• LiFePO4 Chemistry: Lithium Iron Phosphate cells deliver a safer, more stable lithium chemistry compared to traditional lithium-ion
• Internal Battery Management System (BMS): Auto-balances cells and provides protection against over-temperature, over-voltage, under-voltage, over-current, and short-circuit conditions
• IP67 Water Resistance: Sealed against water intrusion, making it suitable for demanding marine environments
• Long Cycle Life: Delivers over 2,500 cycles at 80% depth of discharge (DoD) — more than five times the cycle life of comparable lead-acid batteries
• Faster Recharging: Accepts charge current up to five times faster than lead-acid batteries
• AGM-Compatible Charging: Compatible with typical AGM battery chargers (see manufacturer notes for restrictions)
• Lightweight Design: Significantly lighter than equivalent lead-acid batteries — some Lithium Pros models are light enough to float
• Higher Voltage Under Load: Maintains a more consistent, higher voltage during discharge compared to lead-acid alternatives
• 96% Energy Efficiency: Converts input energy to stored energy at approximately 96% efficiency versus ~75% for lead-acid
• No Toxic Materials: Free of lead and acid; uses the safest form of lithium chemistry

Assembled and tested in Tennessee, the Lithium Pros L22-12 is a direct upgrade from traditional lead-acid or AGM batteries for anglers, boaters, and outdoor enthusiasts who demand reliable, long-lasting power on the water.
