Welcome To Evlithium Best Store For Lithium Iron Phosphate (LiFePO4) Battery |
 |
The Evlithium 51.2V 100Ah LiFePO4 Battery Pack is a wall-mounted energy storage cabinet built with grade A lithium iron phosphate (LiFePO4) cells in a 16S1P configuration (IFR-3.2V-16S1P). Delivering 5.12kWh of nominal energy at 51.2V, it is designed as a drop-in replacement for lead-acid banks in solar off-grid, hybrid, and backup power applications.
An integrated Battery Management System (BMS) continuously monitors cell voltage, current, and temperature, providing overcharge protection, over-discharge protection, over-current cutoff, short-circuit protection, and active cell balancing. The BMS communicates with compatible inverters via CAN, RS485, and RS232 protocols, and supports up to 16 parallel units through the RS485-2 slave bus for scalable multi-kWh storage arrays.
Housed in a rugged iron enclosure (526 × 440 × 134 mm, 43.6 kg), the pack features high-current feed-through terminal blocks, a 2-channel dry contact alarm output, LED status indicators (power, run, alarm, SOC), and a DIP-switch address setting for parallel configurations. With 3000+ cycles at 80% DoD and a wide operating temperature window, this battery pack delivers years of reliable daily cycling.
Built for reliable, long-life energy storage — every detail engineered for performance and safety.
100Ah nominal capacity at 51.2V delivers 5.12kWh usable energy per unit. Scale up by paralleling up to 16 units for larger storage systems.
Built-in battery management system protects against overcharge, over-discharge, over-current, short circuit, and cell imbalance — with automatic equalization.
Grade A LiFePO4 cells deliver over 3000 charge-discharge cycles with 80% capacity retention at 0.5C — outlasts lead-acid by 5x.
CAN, RS485, and RS232 ports ensure seamless integration with most inverters (Hybrid, Off-grid, On-grid). Monitor real-time data via PC software.
Up to 16 battery units can be connected in parallel via RS485-2 bus. Each BMS address is set via DIP switch for easy system expansion.
Discharge operates from -20°C to +60°C; charging from 0°C to +55°C. Reliable performance in diverse climate conditions.
