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

This lithium polymer battery pack is designed specifically for remote control hobbyists who need a power source that fits constrained spaces within their models. With its 7.4-volt output and 1200mAh capacity, it delivers the necessary energy for running small motors and electronics in RC cars, boats, and other vehicles. The 2S configuration provides a balance between voltage and physical size, making it a practical choice for applications where every gram and millimetre counts. Its defined dimensions allow modellers to plan their builds accurately, ensuring a clean installation without power compartment modifications.

Features and Construction

The battery's specifications are centred on providing reliable power within a very specific footprint. Its construction uses lithium polymer cell technology, which is common in the RC sector for its favourable power-to-weight ratio. This focus on dimensional data means users can verify fitment before purchase, reducing the risk of incompatibility with their existing model chassis or hull.

Material and Build

Constructed as a 2S lithium polymer pack, the battery utilises cells configured to deliver a nominal 7.4 volts. The term '2S' indicates two cells connected in series, a standard arrangement for this voltage class. The build is centred around achieving the stated dimensions, with the cell layout and wiring designed to occupy the 15x36x70mm space efficiently. The external casing is likely a lightweight shrink wrap or hard case, though the exact material is not specified, reflecting the need to keep the overall package as light as possible for model performance.

Size and Practical Fit

The primary differentiator of this battery is its precise physical measurements: 15mm in width, 36mm in height, and 70mm in length. This rectangular form factor is intended for integration into model compartments where space is at a premium. For a modeller, these dimensions allow direct comparison with their vehicle's battery tray or available cavity. The compact nature suggests its use is targeted at smaller 1:18 or 1:24 scale cars, micro drones, or scale boats where a larger, higher-capacity pack would be impractical or impossible to fit.

Uses and Placement

This battery's defined voltage and size dictate its ideal applications within the RC hobby. It serves as a direct power source for the electronic speed controllers, receivers, and servo systems found in numerous ready-to-run and kit-built models. The emphasis on a small form factor opens its use to a range of compact vehicle types beyond just cars and ships.

Event or Professional Use

In organised RC racing or competitive events for smaller vehicle classes, a battery with these exact dimensions can be crucial for meeting technical regulations or fitting approved chassis. Its 1200mAh capacity provides a balance between sufficient run time and minimal weight, which can affect lap times and handling. For scale model boating, the low profile (15mm thickness) can be advantageous for keeping the centre of gravity low in the hull, improving stability on the water. The lack of specified discharge rate (C-rating) in the source material means users should confirm its suitability for high-drain applications through testing or manufacturer data.

Everyday Home Use

For the casual hobbyist running models in a garden, park, or pond, this battery offers a straightforward power upgrade or replacement for stock units. Its 7.4V output is compatible with a wide range of consumer-grade RC electronics, making it a versatile spare or primary pack. The single-unit supply means it is sold individually, suitable for those needing one battery for a specific model rather than a multi-pack for frequent swapping. Its practicality lies in its plug-and-play nature for systems designed around this voltage and physical size.

Benefits and Buying Value

The value of this product is rooted in its specification-matched design for a niche requirement. It solves the problem of powering a small RC model without resorting to custom modifications or using undersized batteries. For buyers, the key decision factors are the confirmed dimensions and the voltage, which must align with their model's requirements.

Reuse and Low Maintenance

As a lithium polymer battery, it follows a standard lifecycle of charge and use cycles common to the technology. Its maintenance involves standard RC LiPo care: using a balanced charger, storing at a partial charge, and avoiding physical damage. The longevity will depend on the user's adherence to these practices rather than any unspecified premium claims. Its reuse value is high within its compatible model ecosystem, as it can be transferred between different vehicles that share the same power requirements and physical constraints.

Why Choose This Product

Select this battery if your primary requirement is a 7.4V pack that must fit within a 15x36x70mm space. It is a focused product for a specific dimensional need, which is its main advantage over more generic batteries. The stated 1200mAh capacity provides a quantifiable runtime estimate for planning sessions. The lack of extensive performance data beyond voltage, capacity, and size means it is chosen primarily for its physical and electrical compatibility, making it a practical, no-surprises component for completing a model build or maintaining an existing one.
