The Residential Energy Storage Series lithium battery module integrates high-capacity, high-safety lithium iron phosphate (LiFePO₄) battery cells.
It adopts a stacked structural design, optimising footprint and vertical space utilisation.
The module features a high-precision Battery Management System (BMS) that monitors and collects real-time voltage and temperature data within each cell.
This enables:
- Intelligent temperature control at the cell level,
- Smart cell balancing,
- Improved system efficiency, and
- Extended battery cycle life.
The battery is enclosed in a cold-rolled steel shell with a shock-resistant structure, ensuring safety and reliability that meet residential standards. It is also designed for high stability and interference resistance, guaranteeing consistent and secure system operation.
