7.4V 1200mAh Lithium Polymer Battery for 2S and 3S RC Cars and Boats

This 7.4V lithium polymer (LiPo) battery pack is engineered to supply power to remote control hobbyist models, specifically those compatible with 2S and 3S configurations. With a stated capacity of 1200 milliampere-hours (mAh), it is designed to provide a balanced combination of voltage and energy storage for a range of model vehicles, from cars to ships. The compact form factor, defined by its precise measurements, allows it to fit into designated battery trays and compartments, making it a direct-fit component for many standard and custom builds. This product is supplied as a single, ready-to-use unit, providing a core power source without additional accessories.

Features and Construction

The battery’s primary specifications define its application and compatibility. The 7.4V output is standard for many 2S lipo systems and is a base voltage for some 3S configurations, making it a versatile power cell for various RC models. Its construction as a lithium polymer battery implies a typical pouch cell design, which is common in the hobby for its balance of power density and form factor flexibility.

Material and Build

As a lithium polymer battery, the internal cells use a lithium-ion technology in a polymer electrolyte format, which allows for the slim, rectangular profile noted in the dimensions. The product listing confirms the battery type and its key electrical ratings but does not specify additional build details such as discharge rate (C rating), wire gauge, or connector type. Therefore, users should verify connector compatibility with their existing model electronics and charger.

Size and Practical Fit

The physical size of 15mm in one dimension by 36mm by 70mm is a critical differentiator. These exact measurements should be checked against the available space in your RC model's battery compartment. A fit within these confines is necessary for safe and secure installation. The compact nature suggests it is suited for mid-sized RC cars, certain boat hulls, and other models where space is a defined constraint.

Uses and Placement

This battery is intended for use within the remote-controlled hobbyist sector. Its specified voltage and capacity point towards applications requiring sustained power over a moderate duration, rather than extreme burst performance. The product name explicitly mentions model cars and ships, indicating its tested or intended use case within these categories.

Event or Professional Use

For hobbyists participating in club races, casual competitions, or scale model demonstrations, a reliable and correctly sized power source is fundamental. This 1200mAh 7.4V pack provides a known quantity of energy, allowing for predictable run times and performance consistency during such events, assuming it is paired with a model whose motor and electronics are rated for this voltage.

Everyday Home Use

For the home enthusiast running models in gardens, parks, or on water, this battery offers a straightforward power solution. The capacity supports extended play or testing sessions, while the standard voltage integrates with many off-the-shelf RC kits and replacements. It serves as a practical spare or primary battery for regular, recreational use.

Benefits and Buying Value

The value of this product lies in its defined specifications and direct application. It eliminates guesswork regarding voltage and size, providing a component that can be selected with confidence if your model's requirements match these exact numbers. There is no implied comparison to other batteries; its value is based solely on its stated attributes.

Reuse and Low Maintenance

As a single lithium polymer battery, its lifecycle depends on proper charging, storage, and usage within safe parameters—practices common to all LiPo batteries. The product enables reuse across multiple running sessions until the cell reaches its end of life. Value is maintained through each cycle of use when the battery is correctly maintained according to standard LiPo care guidelines.

Why Choose This Product

Choose this battery if your primary selection criteria are a 7.4V output, a 1200mAh capacity, and physical dimensions of 15x36x70mm. It is a logical choice when these three metrics align with your model's documented needs or empty battery tray size. It provides a specific solution rather than a generic one, which can be advantageous for ensuring compatibility and fit.
