Key Features：
1. Exceptional Cycle Life for Long-Term Reliability
The ETC 3.2V 280Ah LiFePO₄ prismatic battery delivers an ultra-long cycle life of more than 7000 times. This means it can withstand thousands of charge-discharge cycles while maintaining stable performance, significantly reducing replacement frequency and long-term ownership costs—ideal for applications like household energy storage and base station backup that demand decade-long durability.2. High Capacity with Efficient Energy Storage
With a nominal capacity of 280Ah and a nominal voltage of 3.2V, this battery stores a large amount of energy in a single cell. Its compact yet robust design (size: T71×W173×H207mm, weight: 2.86kg) ensures maximum energy density, making it perfect for large-scale energy storage systems, solar/wind energy storage, and UPS backup where high-capacity, space-efficient solutions are critical.3. High Efficiency with Low Internal Resistance
With an extremely low internal resistance of ≤0.4mΩ, the battery minimizes energy loss during charge and discharge. This high efficiency ensures maximum power delivery for demanding applications like solar storage and UPS backup.
4. Wide Operating Temperature Range
Application:
1. Household Energy Storage
The ETC 3.2V 280Ah LiFePO₄ prismatic battery’s high capacity and long cycle life make it an excellent choice for home energy storage. It stores excess energy from solar panels or the grid, providing backup power during outages and reducing reliance on utility electricity—enhancing energy independence and cost savings for homeowners.
2. Solar Energy Storage
In renewable energy setups, this battery efficiently stores energy generated by solar panels or wind turbines. Its 280Ah capacity and stable voltage (3.2V) ensure smooth integration with solar/wind inverters, enabling reliable power supply even when sunlight or wind is unavailable. This supports off-grid living, remote area electrification, and grid-tied renewable systems.
3. UPS Backup Systems
For critical infrastructure like data centers, communication base stations, and industrial facilities, uninterrupted power is essential. The ETC 280Ah battery’ fast response, high capacsity, and long cycle life provide robust backup power during grid failures, preventing data loss, service disruptions, and operational downtime.
4. Portable Energy Storage
While designed for large-scale use, its compact form factor (relative to its capacity) and high energy density also suit high-power portable energy storage systems. It powers tools, appliances, and equipment in outdoor work sites, emergency response scenarios, or mobile operations—delivering sustained, reliable power on the go.
