LiTime 12V 400Ah LiFePO4 Lithium Battery With 250A BMS, 5120Wh Usable Energy

High Quality Lithium Battery Cells. LiTime's 12V 400Ah lithium battery uses Automotive Grade LiFePO4 Cells with UL Testing Certification, offering higher energy density (37.12 Wh/lb), stable performance, and an exceptional 3% self-discharge rate. With a life span of 10 years and 4000-15000 cycles, the battery outperform lead-acid counterparts.

Lightweight & Versatile. Weighing just 86.2 lbs and designed in a Group 8D size, LiTime lithium-ion battery is 1/3 the weight of equivalent lead acid batteries, making it ideal for various applications. Its IP65-level waterproof case, and convenient handles provide flexibility for indoor or outdoor installation.

100% Protection from 250A BMS. Equipped with a built-in 250A BMS (Battery Management System), our 12V 400Ah LiFePO4 battery ensures protection from overcharge, over-discharge, over-current (250A), high temperature (167°F), and short circuits. This battery offers complete peace of mind with no memory effect, ensuring usability regardless of its charging state.

3200W Power & Fast Charging. Offering 3200W high load power, our 12V 400Ah lithium battery is perfect for various applications including RV, marine, camping, solar home, and more. It supports 100% SOC & DOD, providing extended lifetime gains compared to lead-acid batteries. A 12V 40A/80A lithium battery charger is recommended for a full charge within 10hrs/5hrs.

Max. 1600Ah Expandable Capacity. LiTime 12V 400Ah lithium ion battery supports series and parallel connections, with a maximum configuration of 4S4P for a 51.2V 1600Ah battery system, delivering 51.2kW output power and 81.92kWh usable energy.  Best choice for off-grid.
