Cells LiFePO4 280Ah 3.2V Welion Grade A+ Solid-State

Key advantages of Welion SHS165-280

• Maximum safety: Hybrid electrolyte prevents fire and explosion even in the event of a puncture or short circuit.
• High heat resistance: Stable construction withstands temperatures up to 130 °C without risk of ignition.
• Top performance in freezing conditions: Enables safe discharge in extreme conditions down to -30 °C.
• High energy density: Higher energy capacity while maintaining compact dimensions and lower weight.
• Extreme durability: Designed for long-term operation with a service life exceeding 8,000 cycles.
• Low internal resistance: Minimal heating and high efficiency even under high loads.
  
  

Full compatibility with LiFePO4 systems

Welion's innovative solid-state technology delivers a superior level of safety and stability compared to standard liquid-electrolyte LiFePO4 cells.

• Identical voltage: Nominal voltage of 3.2 V and upper charging limit of 3.65 V correspond exactly to the LiFePO4 standard.
• Easy integration: works seamlessly with BMS, balancers, and converters designed for LiFePO4 systems.
• Extended operating range: the discharge limit above 0°C is the same 2.5 V, and at sub-zero temperatures, the cell operates safely down to a voltage of 2.0 V.
