Why 7C + 292Wh/kg is the Perfect Balance for Drone Batteries
Most drone batteries force a trade-off: high-energy-density cells deliver long flight time but lack power for aggressive maneuvers, while high-rate cells deliver massive current but sacrifice endurance. The AS-B088J9 breaks this compromise with 292Wh/kg energy density AND 7C continuous (210A) discharge — enough power for FPV drone acrobatics and heavy-lift takeoff, while still delivering long flight time for industrial drone and long range drone missions.
| High-Energy-Density Drone Cell | 343~380 Wh/kg | 2C~3C discharge |
| High-Rate Drone Cell | 215~220 Wh/kg | 12C~15C discharge |
| AS-B088J9 Balanced Drone Cell | 292 Wh/kg | 7C discharge (Best of Both) |
Core Advantages
- ✔
Perfect Power-Endurance Balance: 292Wh/kg energy density combined with 7C continuous (210A) and 10C peak (300A) discharge — delivers both long flight time and aggressive maneuver capability for FPV drone and industrial drone platforms. - ✔
Ideal for 6S & 12S Drone Battery Packs: The 3.8V high-voltage platform and 30Ah capacity make this the perfect lipo battery for drone pack builders — assemble 6S drone battery (22.8V) or 12S drone battery (45.6V) packs with balanced power and endurance. - ✔
Low ≤2mΩ Internal Resistance: Minimizes voltage sag during 7C high-discharge operation, reducing heat generation and improving overall efficiency — reliable power delivery for both FPV drone racing and long range drone cruising. - ✔
