Semi-Solid-State Drone Battery Key Benefits

1. Ultra-High Energy Density

Delivers an impressive energy density of 350–450 Wh/kg, a significant improvement over conventional lithium-polymer batteries, which typically offer around 200 Wh/kg.

2. Extended Battery Runtime

Higher energy density allows more energy to be stored at the same battery weight, providing longer operating times and extended runtime for battery-powered devices.

3. Custom Multi-Cell Battery Pack Assembly

We offer customized multi-cell battery pack assembly, including 4S, 6S, and other series configurations. Wire gauges and connectors can be tailored to specific current requirements, with popular connector options such as XT60 and XT90.

4. Stable Discharge Performance

Maintains consistent discharge performance across different C-rates, with stable discharge curves and high delivered-capacity percentages.

5. Precision Cell Matching Before Shipment

All cells undergo matching before shipment, whether supplied individually or assembled into battery packs. For example, in a 5S configuration, five cells are carefully matched for capacity, voltage, and internal resistance to ensure consistency and reliable pack performance.

6. Long Cycle Life

Supports up to 500 charge-discharge cycles with 80% capacity retention(25℃,0.2C), providing dependable performance over extended use.

7. High-Volume Production Capacity

Our fully automated manufacturing facility supports large-scale production, with a daily capacity of up to 1.6 million Ah, equivalent to approximately 160,000 cells per day based on a 10 Ah cell capacity. This enables us to efficiently fulfill high-volume orders and support large-scale OEM/ODM projects.

Semi-Solid-State Battery Cell Capacities and UAV Applications

The following capacities refer to individual semi-solid-state lithium battery cells, not complete UAV battery packs. Actual applications depend on battery pack configuration, operating voltage, discharge current, payload, and flight endurance requirements.

Cell Capacity	Typical UAV Applications	Key Features & Selection Considerations
12–16 Ah	Small to mid-sized industrial UAVs and inspection drones	Moderate cell capacity with flexible series and parallel configurations, suitable for applications with weight and space constraints.
17–25 Ah	Industrial multirotor UAVs, fixed-wing drones, and VTOL aircraft	Offers a balance of cell capacity, weight, and system integration flexibility for various industrial UAV battery configurations.
26–35 Ah	Long-endurance fixed-wing UAVs, VTOL drones, and specialized industrial platforms	Suitable for higher-energy applications where flight endurance, total pack weight, and discharge performance must be carefully balanced.
36–40 Ah	Larger industrial UAVs and high-capacity UAV battery systems	Higher capacity per cell supports high-energy battery pack designs, with careful consideration of continuous discharge capability, thermal management, and mechanical integration.

Note: These are general application guidelines rather than fixed capacity recommendations. Final cell selection should be based on the UAV's electrical, mechanical, and flight performance requirements.

Frequently Asked Questions (FAQ)

1. Is the 300–450 Wh/kg energy density measured at the cell or battery pack level?

The 300–450 Wh/kg energy density refers to the individual battery cell, not the complete battery pack.

2. How much can semi-solid-state batteries extend UAV flight time?

Traditional LiPo cells typically offer 150–250 Wh/kg, while our popular semi-solid-state batteries achieve 350–400 Wh/kg. Compared to a typical 200 Wh/kg LiPo cell, this could theoretically extend flight time by 75%–100% at the same cell weight. Actual results depend on the UAV configuration and operating conditions.

3. Can you customize the voltage, capacity, and dimensions of UAV battery packs?

Yes. We offer custom UAV battery packs with flexible voltage, capacity, and dimensions. Cables, connectors, and protection circuits can also be configured to meet your requirements.

4. How do semi-solid-state batteries perform in low temperatures?

Our semi-solid-state batteries support charging from 0°C to 55°C and discharging from -20°C to 55°C, with ≥60% capacity retention at -20°C under specified test conditions.

5. Can you customize battery cables and connectors?

Yes. We offer customized cables and connectors. If you're unsure which option to choose, our engineers can recommend a suitable solution based on your current requirements and equipment.

6. What are your MOQ, lead time, and production capacity?

For in-stock standard sizes, no MOQ is required, and orders can ship within 3 days. For custom sizes, MOQ depends on battery capacity and dimensions. Our production capacity reaches up to 160000 cells per day.

7. How do you ensure cell consistency in custom UAV battery packs?

Before pack assembly, cells are carefully matched based on capacity, voltage, internal resistance, self-discharge rate, and other key performance parameters to ensure optimal battery pack performance, consistency, and reliability.

8. Do you provide engineering samples and performance test data before bulk orders?

Yes. We can provide engineering samples and available performance test reports for evaluation before bulk production.
