High-density semi-solid batteries are transforming energy storage, and DEFNOCO leads with its 350Wh/kg and 400Wh/kg models. These innovations redefine what’s possible for drones and beyond.
350Wh/kg Semi-Solid Batteries: Balance of Power and Practicality
DEFNOCO’s 350Wh/kg semi-solid battery excels in versatility. It delivers 10C discharge rates, ideal for mid-sized drones used in agriculture or mapping.
- Extended Flight Time: Powers 2-hour missions, reducing the need for frequent swaps.
- Lightweight Design: Cuts drone payload weight by 15%, boosting agility.
- Stable Performance: Maintains 90% capacity in temperatures from -10°C to 45°C.
Farmers rely on it for all-day crop monitoring, while surveyors cover larger areas without interruptions.
400Wh/kg Semi-Solid Batteries: Peak Efficiency for Heavy-Duty Tasks
For industrial drones and high-demand gear, DEFNOCO’s 400Wh/kg model is a game-changer. Its ultra-high density enables:
- 2.5-Hour Flight Windows: Perfect for long-range inspections or logistics deliveries.
- Higher Payloads: Supports heavier sensors like LiDAR, critical for infrastructure checks.
- Fast Recharge: 80% capacity in 45 minutes, minimizing downtime for busy operations.
Energy companies use it to monitor remote wind farms, while delivery services extend their reach.

Why These High-Density Semi-Solid Batteries Stand Out
Both models share DEFNOCO’s signature safety features: gel electrolytes eliminate leakage risks, and built-in thermal guards prevent overheating.
- Long Lifespan: Retain 85% capacity after 500 cycles, outlasting traditional lithium-ion options.
- Eco-Friendly: Uses 30% less rare materials, aligning with sustainable operations.
High-density semi-solid batteries from DEFNOCO don’t just store energy—they enable new possibilities. Whether for commercial drones or industrial equipment, these models set a new standard for efficiency and reliability.
Choose DEFNOCO, and power your operations further than ever before.
