Key Product Advantages

1. Standard 1P4S Reliable Configuration

The 1P4S series connection structure provides a stable 12.8V nominal voltage, perfectly matching low-voltage energy storage equipment, backup power supplies and small industrial battery systems. The single-parallel and four-series layout ensures balanced current distribution and uniform cell operation, avoiding inconsistent attenuation caused by unreasonable structural design. It serves as a universal and interchangeable core module for modular energy storage solutions.

2. Ultra-Long Cycle & Low Attenuation LFP Cells

Adopting high-quality long-cycle LFP cells, the module supports more than 6000 deep cycles with extremely low capacity attenuation. Compared with ternary lithium batteries, LFP technology features better thermal stability, stronger overcharge resistance and longer service life. It maintains stable capacity output during long-term frequent charge-discharge cycles, greatly reducing battery replacement frequency and overall project operating costs.

3. Comprehensive Multi-Dimensional Safety Protection

Built with an integrated protection circuit and structural safety design, each 1P4S battery module realizes full-range safety monitoring and protection. It effectively prevents abnormal conditions such as overcharging, overdischarging, overcurrent, short circuit and overheating. The flame-retardant shell and insulated structural design enhance mechanical stability and fire resistance, ensuring safe operation in commercial, industrial and outdoor environments.

4. Easy Integration & Flexible Expansion

With standardized size and consistent electrical parameters, the 1P4S battery module supports series and parallel combination for capacity and voltage expansion. It can be freely stacked and matched to meet different voltage and capacity requirements of customized energy storage systems. The pluggable and modular design simplifies system assembly, shortens project integration cycles and reduces manual installation errors.
