Joysun 30Ah 5C Discharge eVTOL Battery
Designed for eVTOL drones, each cell operates at 3.7V to match mainstream ESC requirements. It delivers stable discharge from -40°C to 60°C and supports custom pack assembly starting from the cell level.
We also offer high-voltage versions with 3.8–3.95V per cell. Please contact us for details.
About Semi Solid State Cells
High-Performance Power | Self-developed | Superior Performance
The semi-solid battery represents an emerging battery architecture.
Compared to conventional lithium-ion batteries, semi-solid batteries deliver higher energy density and superior thermal stability. They are widely adopted in industrial drone battery systems, robotics, and other advanced applications.
Comparison of Joysun semi-solid vs. liquid Li-ion cells:
| Joysun semi soild state | tradition liquid state | |
| Energy Density | 400+Wh/kg | 180~260Wh/kg |
| Safety | Excellent (Non-flammable) | Standard (Thermal risk) |
| Cycle Life | 800+Cycles | Standard |
| Low-Temp Performance | Better（-40~60℃） | Fair |
| Rate Capability | Good (High-rate ready) | Excellent (Ultra-high C-rate) |
