5. Application Scenarios Module
- Small and medium-sized drones / UAV short flights.
6. Usage Precautions
- Must use dedicated lithium battery charger matching this pack voltage (Max charging voltage 4.25v/battery cell); prohibit mismatched chargers to avoid overcharging and swelling.
- Strictly avoid over-discharging below 3.3V/cell cut-off voltage to prevent permanent capacity attenuation and cell failure.
- For long-term storage over 7 days, adjust single cell voltage to nominal storage voltage 3.7V/battery cell and store in a dry environment below 25℃.
- Not recommended for FPV racing drones with frequent extreme acceleration and instantaneous overload flight.
Every Rated Specification, Verified by Real World Testing.
At Auline, product performance is presented through real test data and verified results rather than inflated specifications.
All Auline batteries are tested using the NEWARE CT 4004 5V300A, a professional battery testing system, to accurately measure and document actual capacity and discharge performance.
No inflated capacity. No exaggerated performance.
Just real data, so you know exactly what to expect from the battery you receive.
