Lithium Pros M75-12S Marine Starting Battery Batteries - 12V 75Ah LiFePO4

Product label may vary. Lithium Pros is transitioning to new labels and part numbers; the item you receive may carry either the previous or the updated label.

The Lithium Pros M75-12S is a 12-volt, 75Ah lithium iron phosphate (LiFePO4) marine starting battery engineered for serious anglers and boaters who demand reliable cranking power and deep-cycle performance in a single, lightweight package. Part of the premium M-Series lineup, this battery is assembled in the USA using EV-grade cells tested to IEC 62133 safety standards.

Key Features:

• LiFePO4 Chemistry: Delivers high cycle life, steady voltage under load, and superior energy density compared to traditional lead-acid batteries
• Significant Weight Reduction: Switching from lead-acid to the M-Series cuts weight by up to 80%, reducing hull weight and improving vessel performance
• IP67-Rated Enclosure: Sealed rigid case provides water and spray resistance, with internal supports to absorb vibration from rough water conditions
• ABYC E-13 Compliant: Ensures seamless integration with existing marine wiring systems for straightforward installation
• Intelligent Battery Management System (BMS): Guards against over-voltage, under-voltage, over-current, short circuit, and temperature extremes
• Smart Cell Balancing: Continuously equalizes cell voltages to maximize capacity and extend service life across thousands of cycles
• Bluetooth Monitoring: Built-in Bluetooth connectivity allows real-time battery status monitoring from a mobile device
• Dual-Mode Cold Weather Heating: Exclusive self-heating functionality enables reliable charging in cold-weather conditions
• 12-Year Transferable Warranty: Industry-leading warranty coverage backed by Lithium Pros
• USA Assembled: Built and tested in Tennessee with premium EV-grade cell components

The M75-12S is a drop-in upgrade from conventional Group 24/27 lead-acid and AGM marine starting batteries. With faster recharge times and maintenance-free operation, it keeps your boat ready on the water rather than waiting at the ramp. Mercury-compliant engine-start configurations are available within the M-Series lineup.
