DUO5128 - 51.2V, 280Ah LFP

DUO Series – Dual Usage Optimizer
Long life lithium-ion (LFP) battery for both telecom power backup and daily energy optimization applications

Excellent Service Life
Ideal for daily cycling applications

The DUO5128 battery is designed with high cycle life (>6,000 cycles) Lithium Iron Phosphate (LFP) battery cells, which is ideal for both general backup power application and daily energy optimization applications, such as peak shaving or load shifting that can create more added values.

Dual-module Design
Ease of installation & VRLA retrofit

With a novel dual-module design that reduces size and weight of each sub-module, this battery makes installation and maintenance easier, while its form factor design is also suitable for replacing telecom VRLA battery, minimizing the retrofit costs and efforts.

Built-in intelligent BMS
Ensuring safe and optimal operations

This battery features a built-in intelligent Battery Management System (BMS) that provides battery status monitoring, automatic protection, and optimization functions. Each battery cell is equipped with a dedicated measurement unit, providing higher accuracy and ensuring safe and optimal operations during its long service life.
