Description
Model AS-A5A5T5 – 3.8V 34Ah 12C High-Rate Long-Cycle Drone Battery Cell
Voltage: 3.8V | Capacity: 34Ah (129.2Wh) | Discharge: 12C Continuous / 15C Peak | Tabs: 70mm Wide | Cycle Life: 1000 cycles | Weight: 588g
The AS-A5A5T5 is a 3.8V 34Ah high-rate long-cycle drone battery cell engineered for large commercial and industrial UAV platforms that demand both extreme power output and exceptional service life. Delivering 12C continuous discharge (408A) and 15C peak discharge (510A), this cell provides the massive sustained current needed for heavy-lift operations, large agricultural spraying, and high-payload professional multirotors.
What sets the AS-A5A5T5 apart is its remarkable 1000-cycle lifespan — unprecedented for a 12C high-rate cell — dramatically reducing the total cost of ownership for commercial drone fleets. With an ultra-low internal resistance of ≤0.8mΩ and extra-wide 70mm tabs, it minimizes voltage sag and heat generation even under maximum 408A continuous load. It also supports 6C fast charging (204A) for rapid mission turnaround. Rated for operation across -20°C to +60°C, this cell is ideal for building custom high-rate drone packs for large agricultural spraying, heavy-lift cargo, large survey, firefighting, and industrial platforms.

12C High-Rate + 1000 Cycles + 70mm Tabs: Built for Maximum Current
Most high-rate drone cells sacrifice cycle life for power — typically lasting only 300~500 cycles. The AS-A5A5T5 delivers 12C continuous (408A) discharge while achieving an exceptional 1000 cycles — doubling the service life of comparable high-rate cells. The extra-wide 70mm tabs handle 408A continuous current with minimal resistance and heat. For commercial drone fleets, this means 50% lower battery cost per flight hour.
