The EG4 LL (Lifetime Lithium) Lithium Iron Phosphate battery is now available at 12.8V (12V) and features a 5.12kWh capacity and 200A internal BMS, while preserving the esteemed features of its predecessor the EG4 LL Battery. 

Comprising of 16 UL listed prismatic 3.2V cells and meticulously tested through 7,000 deep discharge cycles to 80% Depth of Discharge (DoD), this battery ensures reliable performance. Capable of daily full charge and discharge for over 15 years without fail, it has undergone rigorous testing and boasts a remarkable 99% operating efficiency. 

Equipped with an LCD screen for convenient access to vital battery information, the upgraded model now supports selectable closed-loop inverter communications, including Victron and EG4. Featuring a user-friendly plug-and-play interface, it includes all essential components for hassle-free setup. 

Each battery comes with a 1-foot RS485 communication cable and a set of parallel cables. For every six batteries, we provide one RS485 USB battery comm cable, which will be shipped separately.
