LiFePO4 314Ah 3.2V Welion Grade A+ Solid-State Cells (R25/6-VI26)

Welion Solid-State SHS165-314Ah

We are introducing technology that represents a major generational leap in the stationary storage segment. The Welion SHS165-314 abandons the commonly used liquid electrolyte—familiar from standard LiFePO4 cells—and replaces it with a semi-solid hybrid electrolyte. This innovation brings a new level of fire safety, chemical stability, and energy density to the world of photovoltaics and traction batteries. For logistical and technical reasons, the cells are sold only in multiples of 4.

Key Benefits of the Welion SHS165-314

• Maximum safety: The hybrid electrolyte prevents fire and explosion even in the event of a deep discharge or short circuit.
• High thermal resistance: The stable design withstands temperatures up to 130 °C without risk of ignition.
• Top performance in cold weather: 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 lifespan exceeding 8,000 cycles.
• Low internal resistance: Minimal heating and high efficiency even under heavy loads.
  
  

Full compatibility with LiFePO4 systems

Welion’s innovative Solid-State technology delivers a higher level of safety and stability compared to conventional LiFePO4 cells with liquid electrolyte.

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