330wh/kg 36000mah 22.2v 6s Solid State Lithium Ion Battery Pack

Product Advantage

Massive energy, record-breaking endurance

36,000mAh / 800Wh provides ~10% more than the 33,000mAh version, enabling medium-size UAVs to fly 60+ minutes (payload-dependent), greatly expanding mission range.

Lightweight design, payload boost

330Wh/kg makes it 30% lighter than LiPo, freeing up weight for an extra 3~5kg of sensors, liquids, or cargo – ideal for logistics and emergency response.

Solid-state safety

 No fire or explosion even under extreme conditions, providing top-tier protection for manned eVTOL and sensitive equipment.

All-climate stable output

Operates from -20°C to 55°C with flat 3C discharge voltage, delivering consistent power in freezing high-altitude or scorching desert environments

Extended cycle life, low TCO

Retains ≥80% capacity after 500 cycles, significantly reducing cost per flight and replacement frequency, lowering total cost of ownership.

Parameter Property

What is this product?

This product is a high-capacity 6S solid-state lithium-ion battery pack with a nominal voltage of 22.2V and a capacity of 36,000mAh, delivering approximately 800Wh of total energy. With an industry-leading energy density of 330Wh/kg, it is about 30% lighter than conventional LiPo batteries of the same capacity. It supports 3C continuous discharge with a flat voltage curve, operates reliably from -20°C to 55°C, and retains over 80% of its initial capacity after 500 cycles. 

Application

Ultra-long endurance UAVs – Border patrol, cross-sea reconnaissance, large-scale mapping, communication relays – cover hundreds of kilometers per flight.

Manned eVTOL air taxis – 800Wh capacity supports short-range intercity trips; solid-state safety meets rigorous aviation certification standards.

Heavy-lift cargo drones – Carry an extra 3~5kg per trip, significantly boosting delivery efficiency, ideal for remote area logistics.

Large industrial robots & underwater vehicles – Powers heavy-duty robots and AUVs with long-lasting energy, reducing recharging interruptions.
