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.
