 Free Shipping | No tax | Door to Door

Ultra-Large Capacity | 32kWh in Single Unit, Double the Value vs 314Ah Kits

• Double capacity, one-unit 32kWh：628Ah high-capacity cell delivers 2x the capacity of 314Ah kits, hitting 32kWh energy storage in a single unit—no parallel connection required at all.
  
  
• Streamlined, low-risk design：Skip tedious wiring/debugging of two 314Ah kits; all-in-one structure eliminates line loss and potential failure risks from multi-group parallel connection for stable operation.
  
  
  

Unbeatable Cost-Efficiency

• Lower overall costs for 32kWh：A single 628Ah kit achieves 32kWh storage at a far lower cost than buying, installing and maintaining two 314Ah kits, cutting extra expenses on components, labor and post-sales upkeep.
  
  
• Max performance with minimal investment：Delivers the same (even better) energy performance, ideal for home solar storage and small commercial use—unbeatable cost-performance for all your energy needs.
  
  

🔒 Top-Tier Safety (Your Peace of Mind First)

• 200A Smart BMS (JK-PB2A16S-30P)：Overcharge/overdischarge/short-circuit/overtemperature protection + 2A active balancing.
  
  
• Optional Fire Extinguisher：Automatically activates at 170℃—eliminates fire risks in high-temperature garages or outdoor setups.
  
  
• Optional Cold-Weather Heating Pad：The BMS is equipped with a heating interface. The heating function is activated when the temperaturedrops below 0 °C during charging and stops automatically at 20 °C.
