12V Lithium Battery 300AH
(12.8V 300AH)

Product Overview

• SUPER EMPOWER designs and develops LiFePO₄ battery systems for RV, marine, trolling motor, and other 12V automotive auxiliary power applications. Each battery features an integrated BMS and LiFePO₄ cells suitable for vehicle-mounted power systems, mobile equipment, and off-grid electrical setups.

Cycle Performance and Certification

• The 12V 300Ah LiFePO₄ battery uses Grade A+ cells and supports long-cycle operation with high energy density. UL and FCC compliance supports integration into automotive replacement battery systems, RV electrical circuits, and marine power systems. It delivers approximately 5000 cycles at 100% DOD (6000 at 80%, 15000 at 60%), with a built-in BMS managing charge, discharge, and temperature conditions.

Drop-in Replacement for Lead-Acid Batteries

• Dimensions: 15.35″D × 7.59″W × 9.84″H, Weight: 58.4 lbs.The 12V 300Ah LiFePO₄ battery is designed to fit standard RV, marine, trailer, and vehicle auxiliary battery compartments. It serves as a lithium-based replacement for traditional lead-acid deep-cycle battery systems, delivering reliable performance for a wide range of mobile and off-grid applications.

Power System Integration

• The Battery Management System (BMS) monitors charge, discharge, current, and temperature parameters. The structure provides resistance to dust, moisture, and salt spray. The low-temperature cut-off supports use in RV electrical power, marine power systems, 12V automotive auxiliary systems, and trolling motor applications, enhancing system protection in varied environments.

Low-Temperature Charging Function

• Charging pauses automatically below 0°C (32°F) and discharge stops at –20°C (–4°F), resuming above 5°C (41°F). This function supports stable operation in cold-weather conditions for RV setups, 12V vehicle auxiliary power, marine applications, and off-grid systems operating in low temperatures.
