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.

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.
