LIO 10.5-IP20 | 51.2V 200Ah Lithium-ion Battery

High-Capacity, Rack-Mount Battery for Energy Storage Systems

The LIO 10.5-IP20 is a robust, rack-mounted lithium-ion battery designed for advanced energy storage needs in residential and commercial solar systems. With a total capacity of 10.24kWh, this low-voltage battery uses long-life prismatic LiFePO₄ cells to ensure safety, scalability, and long-term performance.

Engineered with an intelligent Battery Management System (BMS), it supports independent protection for charging and discharging, seamless communication with leading inverter brands, and parallel expansion of up to 15 sets. Its standard 19” rack size and plug-and-play design make it simple to install and maintain, while its wide operating temperature range allows reliable operation even in harsh environments.
