What are the key features of the 48V 100Ah rack-mounted LiFePO4 battery?

This battery provides a nominal voltage of 51.2V and a capacity of 100Ah, storing approximately 5120Wh of energy. It supports continuous charge and discharge currents up to 100A, with peak discharge currents reaching 200A. The battery is housed in a compact 3.5U rack-mounted metal enclosure with IP20 to IP65 protection options. It weighs about 45-46 kg and measures roughly 495 x 483 x 177 mm. The integrated BMS offers comprehensive protections including overcharge, over-discharge, overcurrent, temperature control, and short circuit prevention.

How does the Battery Management System (BMS) ensure safety and longevity?

The BMS continuously monitors cell voltages, current, temperature, and state of charge to prevent overcharge, deep discharge, overheating, and short circuits. It balances cell voltages to optimize usable capacity and extend battery life. Advanced communication protocols like RS485, CAN bus, Bluetooth, and optional 4G enable real-time monitoring and predictive maintenance.

Why is LiFePO4 chemistry ideal for rack-mounted battery systems?

LiFePO4 chemistry offers superior thermal stability, long cycle life exceeding 6000 cycles at 80% depth of discharge, and high energy density. It maintains stable voltage output, resists thermal runaway, and features a low self-discharge rate (~3% per month). Compared to lead-acid batteries, it is lighter, charges faster, and requires minimal maintenance.
