Performance of AirThunder Battery

AirThunder batteries are able to maintain a consistent voltage throughout the discharge cycle. The figure below shows the discharge of our 3S1P battery at various current draw. Voltage of most other batteries falls below 9 volt shortly after initial discharge while our battery maintains a voltage around 10V for much of the discharge cycle. A consistent voltage ensures that you always get the top performance.

 

AirThunder batteries are also durable. The chart below shows that our batteries still retain 90% of the original capacity after 100 charge/discharge cycles. The study was done with 20A current draw.

Below is the same study done at 30A.
