Why Solid-State

Built around solid-state energy

Every pack in the series trades chemistry for a lighter, safer and more durable flight envelope.

350 to 400Wh/kg

High energy density

More usable energy in a smaller, lighter enclosure, letting airframes carry further or fly longer on the same mount.

Lighter weight

A leaner pack reduces airframe load and extends every mission envelope without adding ballast.

Longer life

Stable chemistry and smart management extend cycle life and reduce fleet replacement cost over time.

Higher safety factor

Thermal stability and layered protection raise the safety margin for demanding industrial missions.

Smart BMS

SOX state estimation, smart parallel and soft-start keep every pack monitored and controlled in flight.

Built for the platforms that carry the mission

From multirotor lifters to VTOL fixed-wing airframes, the series is engineered for industrial duty.

Multirotor

Heavy-lift multirotors

High-capacity packs for spraying, seeding, surveying and cargo platforms that need dependable endurance.

Fixed-Wing

VTOL fixed-wing

Energy-dense cells for long-range VTOL fixed-wing airframes balancing hover power with cruise efficiency.

Industrial

Logistics & emergency

Reliable power for logistics delivery and emergency-response UAVs operating in demanding environments.

Frequently asked questions

The series reaches a peak energy density of 350 to 400 Wh/kg, depending on the cell and configuration. Higher energy density supports longer range or lighter carrying weight on the same airframe.
The operating temperature range is -20°C to 55°C. Charging and discharging limits should be confirmed separately in the datasheet for your specific configuration.
The series is engineered for multirotor and VTOL fixed-wing drones across logistics, agriculture, surveying and emergency-response missions.
Discharge rates range from 3C continuous (10C peak) to 5C continuous (10C peak) depending on the model. See the full model list for each capacity.
Yes. Voltage, capacity, series and parallel configuration, connectors, BMS, enclosure and branding can all be tailored to your platform through the OEM evaluation process.
