About This

【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 × 9.84"W × 7.24"H; Weight: 58.4 lbs. Designed to match BCI Group 31 automotive battery size, the 12V 300Ah LiFePO₄ unit fits standard RV, marine, trailer, and vehicle auxiliary battery compartments. It functions as a lithium-based automotive replacement battery for traditional Group 31 lead-acid deep cycle systems.
【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.
【Expandable Energy Configuration】Supports up to 4 in series and 4 in parallel (Max 4S4P), forming a 51.2V 1200Ah configuration with 61.44kWh capacity. Suitable for RV energy systems, automotive auxiliary power, marine power, and solar storage, with the integrated BMS managing cell balancing and multi-battery operation.
【Packaging Information】Products are distributed through authorized SUPER EMPOWER facilities in the U.S. Packaging design may vary due to updates, but all batteries maintain the same manufacturing and quality standards for RV, marine, and automotive replacement battery applications.
【5-Year Warranty】Each LiFePO₄ battery includes a 5-year limited warranty covering manufacturing defects under normal use. SUPER EMPOWER provides post-purchase support in accordance with standard product service policies to maintain customer satisfaction.
