7.4V 1200mAh 2S LiPo Battery for Remote Control Cars and Model Aircraft

This lithium polymer battery is designed as a power source for radio-controlled toys and hobbyist models operating on a 2S configuration. With a voltage of 7.4V and a capacity of 1200mAh, it provides the electrical energy needed to run small motors and electronics in model cars, drones, and aircraft. Its notably compact form factor allows it to fit into chassis and fuselages where internal space is a primary constraint. The included JST plug offers a direct connection point for many standard speed controllers and receiver systems, simplifying the installation process for modellers.

Features and Construction

The battery's specifications are defined by its voltage, capacity, and physical size, which are the key factors for matching it to a model.

Material and Build

Constructed using Lithium Polymer (LiPo) cell technology, this battery provides the power density typical of this chemistry. It is supplied with a JST connector soldered to its output wires, which is a common interface for low to medium-current applications in the RC hobby. The external casing is a hard plastic shrink-wrap, which provides basic protection for the internal cells and helps maintain the pack's stated rectangular dimensions.

Size and Practical Fit

The battery's dimensions are precisely 15mm wide, 36mm deep, and 70mm long. This slim profile is crucial for installation in scale model cars with low-clearance chassis, the compact bays of mini drones, or within the narrow fuselage of model aircraft. Before purchase, modellers should verify these measurements against the available space in their specific model to ensure a proper and secure fit.

Uses and Placement

This power cell is suited for a range of small-scale radio-controlled applications where a 2S battery system is specified.

Event or Professional Use

For organised club racing or drone flying events involving smaller vehicle classes, this battery can serve as a practice or backup power pack. Its capacity allows for reasonable session lengths, while its size conforms to the strict dimensional rules often found in specific racing categories. It is important to check event regulations regarding battery specifications and connector types before use in competition.

Everyday Home Use

For the hobbyist operating scale model cars, boats, or aircraft in a garden, park, or indoor setting, this battery offers a straightforward power solution. Its 1200mAh capacity is suitable for extended casual running sessions, and the common JST connector means it can often be used interchangeably between different compatible models owned by the same enthusiast, maximising its utility.

Benefits and Buying Value

The value of this product lies in its defined specifications matching a clear need within the RC modelling hobby.

Reuse and Low Maintenance

As a single, self-contained unit, the battery can be used across multiple compatible RC models over time, representing a reusable component rather than a consumable. Proper care, including using a balanced LiPo charger and safe storage practices, can help maintain its performance. No specific cycle life or longevity data is provided by the source, so performance should be assessed through practical use.

Why Choose This Product

This battery is a practical choice when the key requirements are a confirmed 7.4V 2S voltage, a 1200mAh capacity, and a compact 15x36x70mm size. It eliminates guesswork for modellers who have measured their battery compartment and know their model's voltage needs. The inclusion of the JST connector also removes the need for the user to solder their own connector, making it a ready-to-run option straight from the packaging.
