400wh/kg 31000mah 42v 12s Solid State Lithium Ion Battery Pack

Product Advantage

Ultra -high energy density (400Wh/kg) 

Delivers 31Ah of capacity at nearly half the weight of conventional Li -ion packs, significantly improving payload, endurance, and portability for drones, robotics, and portable devices.

Large capacity & high voltage (31Ah / 42V / 12S)

Provides sustained high -power output and extended runtime, supporting demanding applications like heavy -lift UAVs, electric vehicles, and industrial equipment without frequent recharging.

Solid -state safety

Non -flammable solid electrolyte eliminates leakage and thermal runaway risks; operates reliably across a wide temperature range (–20°C to +60°C) with excellent overcharge/over -discharge tolerance.

Long cycle life

Solid -state chemistry minimizes internal degradation, offering >2,000 deep cycles at 80% DOD – drastically reducing total cost of ownership over the battery's lifetime.

Parameter Property
