Polarium SLB48-100-135-6 LFP Battery
The Polarium SLB48-100-135-6 is a compact, smart lithium battery built for mission-critical telecom and industrial power applications. Delivering 5120Wh of usable energy in a 3U 19" rackmount form factor, it leverages advanced Lithium Iron Phosphate (LFP) chemistry for exceptional safety, long cycle life, and thermal stability. Designed and manufactured to meet global standards, the battery features Polarium’s proprietary battery management system (BMS) with intelligent protections, automatic cell balancing, and secure remote monitoring. Native integration with leading DC power system controllers including Eltek ensures seamless deployment in hybrid, grid-connected, and off-grid applications.
Features
- High energy density in compact footprint: 5120Wh capacity in a 3U 19” enclosure (440mm x 441mm x 132mm), weighing only 39.3 kg.
- Advanced LFP chemistry: Delivers long cycle and calendar life, superior thermal stability, and inherently safer cell chemistry.
- Smart BMS: Integrated battery management system ensures charge balancing, fault monitoring, and automatic protection against over-voltage, over-current, and temperature excursions.
- Flexible communications: Supports RS485 and dual RJ45 ports with Modbus protocol for integration into remote monitoring systems.
- Wide operating range: Supports charging from 0 to +55°C and discharging from -20 to +60°C.
- High power performance: Capable of 6kW peak discharge for 60 seconds and up to 100A continuous discharge.
