High Energy 850mAh 4S 15.2V 120C LiPo Battery for 2-25 Inch Model Aircraft

This 850mAh 4S lithium polymer battery pack offers a high discharge rate of 120C, making it suitable for power-hungry RC aircraft and racing drones from 2 to 25 inches in size. With a nominal voltage of 15.2V and a compact footprint, it provides reliable power for sustained flight sessions. The pack weighs approximately 88g and is available with XT30 or XT60 discharge connectors to suit common power systems.

Features and Construction

Built to deliver consistent performance, this battery combines high energy density with a lightweight design. Its 4S1P arrangement provides a balance of voltage and capacity for mid-sized models.

Discharge Performance

The 120C continuous discharge rate supports high-amperage draws during aggressive flying. This ensures responsive throttle and stable voltage under load for racing drones and sport aircraft.

Compact Dimensions

Measuring only 26.5 x 30 x 63mm, this pack fits easily into narrow fuselages and drone frames. The slim profile helps maintain aerodynamic efficiency without interfering with other components.

Connector Options

Choose between XT30 and XT60 discharge plugs. Both are common in RC applications, allowing straightforward integration with existing ESCs and wiring harnesses without adapter cables.

Uses and Placement

This battery is designed for electric-powered model aircraft and multirotors where weight and discharge capability are critical. Its size and power characteristics suit both park flyers and competition drones.

Racing and Sport Flying

The 120C discharge rate meets the demands of high-throttle racing drones and aerobatic fixed-wing models. Pilots benefit from consistent power delivery during sharp turns, climbs, and straight-line sprints.

Everyday Flying

For general sport flying, the 850mAh capacity provides practical flight times without excessive weight. The compact size helps keep the model's centre of gravity manageable for predictable handling.

Benefits and Buying Value

This pack offers a strong balance of power, weight, and fit for many mid-range RC models. Its construction supports repeated charge cycles when handled correctly.

Reuse and Maintenance

LiPo batteries require proper charging and storage practices to maximise lifespan. Using a balance charger and storing at storage voltage helps maintain cell health over multiple seasons of use.

Why Choose This Product

With a high 120C discharge rating and dual connector options, this battery is a practical choice for hobbyists needing reliable power in a lightweight 4S format. The 850mAh capacity is well-matched to models sized 2 to 25 inches.
