Rept’s Grade A 280Ah LiFePO4 prismatic cells are designed for dependable, long-term energy storage across residential, commercial and off-grid applications.
These cells provide stable, repeatable performance whether used in compact modular systems or large-scale battery banks.
Each unit is precision-tested for capacity, internal resistance and dimensional accuracy, ensuring consistent behaviour when assembled into multi-cell packs. This level of quality control supports long cycle life, balanced charging and reliable high-output performance.
Using proven LiFePO4 chemistry, the cells deliver excellent thermal stability, a strong safety profile and predictable degradation characteristics. They are well-suited for solar energy storage, campervan and marine power systems, industrial backup applications and DIY battery builds where reliability is essential.
Unmatched Durability and Lifespan
- Engineered for long service life with ≥8000 cycles at 25°C to 70% SOH.
- Stable LiFePO4 chemistry and controlled manufacturing ensure predictable performance across demanding applications.
Exceptional Capacity for Extended Use
- Reliable 280Ah nominal capacity and 896Wh nominal energy provide strong usable storage for off-grid, solar and commercial systems.
- Wide operating temperature support, including 0°C to 60°C charging and -30°C to 60°C discharging, ensures dependable operation in variable environments.
- High efficiency performance (up to ≥94 percent at 0.5C) helps maximise usable energy during daily cycling.
Consistent, High-Grade Cell Construction
- Cell dimensions: 71.7mm thickness, 174.0mm width, 206.9mm total height.
- Low resistance (≤0.25mΩ) ensures stable operation
- Designed for safe expansion forces and long-term structural integrity.
Seamless Integration
- Standard screw terminals for straightforward mechanical and electrical integration.
- Suitable for flexible pack configurations including 12V, 24V and 48V builds.
⚠ 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.
