Scalable 20kWh Home Energy Storage Solutions Built on Precision Engineering

A Reliable 20kWh Energy Storage Core by LEMAX

As energy storage applications continue to expand, battery reliability and scalability have become critical. At LEMAX, we focus on what matters most—the battery itself.

By pairing two LMW 10kWh lithium battery units, a stable 20kWh storage core can be formed with ease. This modular design allows for smooth scalability while maintaining consistent performance and long-term reliability.

Precision Engineering at the Cell Level

Performance starts with data, and data starts at the cell level.

LEMAX applies strict cell selection, matching, and validation processes to ensure balanced capacity and stable behavior throughout the battery pack. This attention to detail delivers long-term cycle stability that goes beyond theoretical specifications and performs reliably in real-world operation.

The result is a lithium battery designed for durability, consistency, and extended service life.

Reliable BMS for Complete Battery Protection

Every LEMAX battery integrates a highly reliable Battery Management System (BMS) that continuously monitors and protects the battery pack.

The BMS provides:

• Real-time voltage, current, and temperature monitoring

• Cell balancing to extend battery lifespan

• Multi-layer safety protection for stable operation

This deep-level oversight ensures both safety and performance, from initial integration through years of daily use.
