The L005-51.2-100 is a rack-mounted lithium iron phosphate (LiFePO4) battery module delivering 51.2V nominal voltage with 100Ah capacity and 5.12kWh nominal energy. Featuring 48 cells configuration, the L005-51.2-100 provides an operating voltage range of 44.8~58.4V with recommended charging voltage of 55.2V. With up to 6000+ cycles @ 80% DOD cycle life at 80% depth of discharge, this battery delivers exceptional longevity for solar energy storage, UPS backup and telecom base station applications.

Compact rack design at 682*510*246 mm and just 93 kg, the L005-51.2-100 fits standard 19-inch racks for space-efficient deployment in energy storage rooms and data centers. Smart BMS with balanced management ensures safe operation with overcharge, over-discharge, overcurrent, short circuit and temperature protection. Multiple units support parallel expansion with automatic address assignment — no DIP dialing required — enabling flexible capacity scaling from 5.12kWh upwards.

Visual communication via LCD display and LED indicators (SOC/ALARM/RUN) provides intuitive operating status at a glance. Dual RS485 interfaces upload cell-level data in real time, while CAN communication supports seamless inverter integration. IP20-rated enclosure with natural air cooling or intelligent fan ensures reliable operation across storage temperatures from -20°C to 55°C and charging temperatures from 0°C to 55°C.
