3 X EG4-LifePower4 V1 Lithium Battery | 48V 100AH | Server Rack Battery | UL1973, UL9540A

*** The three batteries have less than 10 charge cycles – literally like new. *** Key Benefits: • Long Battery Life: Over 6,000 deep discharge cycles at 80% DoD ensure reliable, long-term performance. • High-Capacity Storage: 51.2V nominal voltage with 5.12 kWh usable energy and 100Ah capacity. • BMS Features: 100A internal BMS with on/off communication switch for easier system setup. • Enhanced Compatibility: CAN bus and RS485 ports support closed-loop communication with a wider range of inverters. • Scalable Energy Storage: Parallel up to 64 batteries for a total of 327.7 kWh, ideal for large-scale systems. • Easy System Integration: New Protocol 6 DIP switch simplifies inverter matching and battery configuration. • Safety-Focused Design: Dual on-board fire arrestors and E-Stop rapid shutdown (RSD) provide additional protection in high-risk environments. • Installer-Friendly Terminals: Two positive and two negative terminals offer convenient connections for chargers, inverters, or EMP shields. • Certified & Tested: UL1973 Recognized Component, UL9540A passed, and UL9540 Listed with EG4 18kPV-12LV. I built this system and used it very rarely, just keeping batteries charged and ready if needed. Inverters or batteries were never powered on more than one day. I can power it on for demonstration if needed. In the picture you will see connecting electrical wiring, protection devices, battery rack and a large circuit breaker panel – these are also available with purchase (small additional cost) if desired. Located in Tucson, Arizona. Use Cases: This battery is ideal for whole-home backup power, off-grid and hybrid solar systems, and commercial or industrial storage banks requiring dependable, high-capacity energy. Its scalable design also supports large multi-battery energy storage systems, while the server-rack form factor ensures secure, code-compliant installation across residential and commercial environments. Tech Specs: • Chemistry: Lithium Iron Phosphate (LiFePO4) • Nominal Voltage: 51.2V • Capacity: 100Ah • Energy: 5.12 kWh • Cycle Life: 6,000+ cycles @ 80% DoD • BMS: 100A internal BMS • Scalability: Up to 64 units in parallel (327.7 kWh max) • Communication: RS485, CAN bus, Protocol 6 DIP switch • Terminals: Dual positive + dual negative terminals • Safety: Internal fire arrestors, E-Stop RSD function IMPORATANT NOTE: I also have 2 x MPP Solar LV6548 6,500W Solar Inverters (13,000W combined capacity) listed separately for sale$1,500 . These inverters were part of the same backup power system and are an excellent match for these EG4 batteries.
