The LB-W5K is a wall-mounted low-voltage energy storage lithium battery that saves valuable floor space and offers two capacity choices — 5,120 Wh (5.12 kWh) or 10.24 kWh — built on LFP cells in a 1P16S configuration at 51.2V. Designed for apartment balconies, home backup power or small convenience stores, it installs quickly with a standard wall mount, stores surplus PV energy, and protects critical loads during outages. It delivers up to 100A maximum charge/discharge current, intelligent BMS monitoring over CAN/RS485, over-charge/discharge, high/low-temperature, over-current and short-circuit protection, plus cell voltage balancing.
