EG4-LifePower4 V2 Lithium Battery | 48V 100AH | Server Rack Battery

The EG4 LiFePOWER4 48V V2 battery maintains the sturdy design and high performance of the original model, while adding new features for an improved user experience and better system integration. This Lithium Iron Phosphate (LiFePO4) battery is composed of 16 UL recognized prismatic 3.2V cells in series, offering over 6,000 deep discharge cycles at 80% Depth of Discharge (DoD). It has a nominal voltage of 51.2V, an energy capacity of 5.12kWh, and an internal 100A Battery Management System (BMS).

The battery supports parallel connections of up to 64 units and includes a 10-year limited warranty. Improved terminal connections make it easier to attach chargers or EMP shields. The LiFePOWER4 48V V2 also features RS485 and CAN bus communication for broader inverter compatibility, along with a new Protocol 6 DIP switch for straightforward and convenient inverter and battery customization. Additionally, the E-Stop (Emergency Stop) rapid shutdown (RSD) functionality ensures fail-safe operation in high-risk environments, and dual on-board fire arrestors provide added peace of mind during operation.
