Highstar’s Grade A 314Ah LiFePO4 prismatic cells are engineered for reliable, long-term energy storage across home, commercial and mobile applications.
Each cell is fully tested for capacity, internal resistance and dimensional consistency, ensuring stable performance in both small and large battery systems.
These cells use proven LiFePO4 chemistry, offering high cycle life, strong thermal stability and dependable safety. Ideal for solar storage systems, camper and marine builds, industrial backup power and large DIY battery projects.
Unmatched Durability and Lifespan
- Designed for long-term reliability with up to 8,000 cycles at 70% SOH at 25°C.
- Advanced LiFePO4 chemistry offers excellent thermal stability and predictable performance over years of use.
Exceptional Capacity for Extended Use
- A true 314Ah minimum capacity provides substantial energy storage for both residential and commercial systems.
- Wide operating temperature capability supports charging from 0°C to 60°C and discharging from -30°C to 60°C, ensuring dependable operation in varied environments.
- High efficiency ≥93 percent helps maximise usable energy and reduce losses throughout daily cycling.
Consistent, High-Grade Cell Construction
- Grade A classification ensures matched internal resistance, capacity and dimensional accuracy.
- Low internal resistance (0.18 ± 0.05mΩ) supports steady output and stable pack performance under sustained loads.
Seamless Integration
- Standard screw terminals support straightforward integration into custom battery assemblies.
- Compatible with bus bars, compression fixtures and BMS systems required for safe operation.
- Suitable for scalable builds including 12V, 24V and 48V configurations.
⚠ Important: These are raw cells, not finished batteries. Only purchase if you’re confident working with lithium cells - they can be hazardous if mishandled or shorted.
