7.4V 1200mAh 2S LiPo Battery for RC Cars and Model Boats

This lithium polymer battery pack provides a reliable 7.4-volt power source specifically designed for radio-controlled models. With a capacity of 1200 milliamp-hours, it delivers sustained energy for longer operation of small to medium-sized RC cars, trucks, boats, and other scale vehicles. Its carefully considered dimensions of 15mm wide by 36mm deep by 70mm high allow it to slot into the constrained battery trays common in many hobby-grade kits and ready-to-run models. The soft outer casing offers some flexibility during installation, while the integrated wiring and standard T-style connector ensure compatibility with a wide range of electronic speed controllers (ESCs).

Features and Construction

This power cell is built around the specifications demanded by hobbyist RC applications, focusing on a balance of output and physical size.

Material and Build

The battery utilises lithium polymer (LiPo) cell technology housed within a flexible polymer soft case. This construction is common in the RC hobby sector as it can accommodate slight variations in mounting space and helps reduce overall weight compared to hard-cased alternatives. The internal cells are configured for a 2S setup, delivering a nominal 7.4 volts. All wiring is pre-soldered and terminates in a common T-plug connector, ready for immediate connection to your model's power system.

Size and Practical Fit

The primary design consideration is its physical footprint. At 15 millimetres wide, 36 millimetres deep, and 70 millimetres tall, this battery is engineered to fit the battery compartments of many popular 1/10 and 1/12 scale land vehicles, as well as similar-sized marine models. These dimensions make it a suitable direct replacement or upgrade for many stock battery packs, and its form factor is a key point for modellers needing to maximise space within a chassis or hull.

Uses and Placement

This battery's specifications directly support its intended use in the remote control hobby world, from casual backyard running to more structured club events.

Event or Professional Use

For club racing or competitive bashing, the 1200mAh capacity provides a solid balance between runtime and weight. In a 2S configuration, the 7.4V output is ideal for brushed and many sensorless brushless motor systems, offering a noticeable power increase over lower-voltage NiMH packs. Its compact size allows racers to place it low in the chassis for better centre of gravity, potentially improving handling in corners and over jumps during off-road events.

Everyday Home Use

For the general hobbyist running models in parks, gardens, or on water, this battery offers a practical power solution. The specified capacity supports extended play sessions, reducing the frequency of charge cycles during a day out. The standard connector means it can often be used as a direct swap into existing models without modification, making it a straightforward upgrade or spare pack to keep your RC car or boat running longer.

Benefits and Buying Value

The value of this battery lies in its targeted application, proven specifications, and the practical advantages it brings to the RC enthusiast.

Reuse and Low Maintenance

As a core component of an RC model's drivetrain, a quality LiPo battery like this is a reusable investment. With proper care using a balance charger and sensible storage practices, it can provide power across many running sessions. Its defined voltage and capacity make charging straightforward with modern chargers, and its physical size remains constant, ensuring it fits the same model repeatedly.

Why Choose This Product

This battery is chosen for its clear and measured specifications: 7.4V and 1200mAh. Unlike vague or overstated claims, these figures allow you to match it precisely to your model's requirements and your ESC's specifications. The provided dimensions let you verify it will physically fit before purchase, eliminating guesswork. It serves a specific function—powering 2S RC vehicles—and provides all the necessary data to confirm its suitability for that role.
