With an 850mAh capacity and 120C discharge rate, it provides a strong balance of flight time and burst performance. The compact 26.5 by 30 by 63mm size fits neatly into smaller airframes without adding unnecessary bulk. Weighing approximately 88 grams, it helps maintain your model's intended weight balance and performance characteristics. Choose between an XT30 or XT60 discharge plug to match your existing power system.

Features and Construction

This battery is built for demanding RC applications where reliable power delivery is essential. The 4S1P configuration provides a nominal voltage of 15.2V, suitable for high-performance models.

Cell Configuration

The 4S1P arrangement connects four cells in series with a single parallel cell group. This setup gives you the higher voltage needed for efficient motor and ESC operation while maintaining a compact physical footprint.

Discharge Performance

With a 120C continuous discharge rate, this battery can deliver sustained high current for aggressive flying. The high discharge capability supports quick throttle response and powerful climbs during racing or acrobatic flights.

Connector Options

The battery is offered with either an XT30 or XT60 discharge plug. XT30 connectors suit smaller models and lighter wiring, while XT60 provides a robust connection for higher current draws commonly seen in racing drones.

Uses and Placement

This battery is designed specifically for compact model aircraft. Its size and weight make it a practical choice for several popular flying categories.

FPV Racing Drones

The 120C discharge rate and 850mAh capacity work well for 2 to 2.5 inch FPV racing drones, such as those using 20x20 or similar stacks. The compact cell size allows easy placement within the frame.

Model Aeroplanes

For small-scale electric model aeroplanes, this battery provides sufficient energy for flight without excess weight. The 15.2V nominal voltage matches many small brushless motor and ESC combinations.

Indoor and Micro Flyers

The lightweight design also suits indoor micro flyers and park flyers where weight savings directly improve handling and flight characteristics.

Benefits and Buying Value

This battery offers practical advantages for RC enthusiasts who need a reliable power source for small models.

Weight and Size Efficiency

Weighing approximately 88 grams and measuring 26.5 by 30 by 63mm, this battery minimises the impact on your model's centre of gravity and overall weight budget.

Ready-to-Use Configurations

With pre-fitted XT30 or XT60 connectors, the battery is ready to install without extra soldering or adapter cables. Choose the connector that matches your existing power leads.

Why Choose This Battery

This pack delivers a proven combination of capacity, voltage, and discharge rate in a form factor that fits the most popular 2 to 2.5 inch RC models. The availability of two connector types adds flexibility for different setups.
