850mAh 4S 15.2V 120C LiPo Battery Pack for 2-25 Inch RC Model Airplanes

When flying electric model aircraft, consistent power delivery and manageable weight are key to a satisfying experience. This 4S LiPo battery pack offers a balanced combination of energy density and discharge capability, designed to suit aircraft from small 2-inch indoor models up to 25-inch outdoor planes. With an 850mAh capacity and 15.2V nominal voltage, it delivers enough punch for spirited aerobatics while fitting neatly into tight fuselage compartments. The 120C continuous discharge rating means you can draw current confidently during full-throttle climbs or sustained runs without voltage sag. Whether you choose the XT30 or XT60 plug, you get secure, low-resistance connections that minimise power loss. This pack is built for RC enthusiasts who want a straightforward, no-fuss power source that works reliably flight after flight.

Features and Construction

This battery uses reliable LiPo chemistry combined with a smart 4S1P layout to keep weight low and performance high. Every specification is chosen to support the demands of electric RC aircraft, from trainers to sport flyers.

Material and Build

Manufactured with high-grade lithium polymer cells, the pack delivers stable voltage under load. The outer shell is a flexible yet tough pouch that withstands typical handling during installation and removal. The 4S1P configuration means four cells are connected in series with one parallel group, giving 15.2V nominal voltage without adding unnecessary bulk. Weighing only around 88g, it suits models where every gram counts.

Size and Practical Fit

Compact dimensions of 26.5mm thickness, 30mm width, and 63mm length allow the battery to slide into many fuselage bays, wings, or hatch compartments. These measurements make it appropriate for micro drones, park flyers, and small-to-medium electric planes. The 850mAh capacity provides a practical flight time while keeping weight in check.

Uses and Placement

This battery pack fits naturally into a range of RC flying applications, from casual backyard flying to more demanding pattern work. Its size and connector options broaden its compatibility across popular model sizes.

Event or Professional Use

At the flying field, this pack works well for practice sessions, aerobatics, and club events. The 120C discharge rate supports dynamic throttle changes without overheating. Pilots flying indoor or small models will appreciate the 88g weight and compact footprint, while larger designs up to 25-inch can still benefit from the punchy 15.2V output.

Everyday Home Use

For hobbyists flying in parks or gardens with 2- to 10-inch models, this battery provides a dependable power source. The balance of capacity and weight allows moderate flight times for relaxed circles or gentle manoeuvres. Plugging in with the XT30 or XT60 connector is quick and secure, so you can spend more time in the air.

Benefits and Buying Value

A well-chosen battery improves your flying experience and reduces total cost over time. This pack focuses on practical strengths that matter to RC pilots: weight, power, and connector versatility.

Reuse and Low Maintenance

LiPo batteries require only basic care—balance charging and proper storage voltage—to provide many cycles. This pack is no exception, offering straightforward maintenance that fits into normal hobby routines. The robust pouch and quality tab welds help maintain cell integrity over repeated use.

Why Choose This Product

Selecting the right battery connector can be a hassle. This pack eliminates that by offering both XT30 and XT60 options, so you can choose the plug that matches your speed controller without adapters. The 120C rating gives headroom for higher-current setups, while the 850mAh capacity suits everyday flying. It’s a practical, no-nonsense choice for pilots who value consistent performance and easy integration.
