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

This 2S lithium polymer battery pack delivers 7.4 volts of power specifically designed for radio-controlled model vehicles and boats. With a capacity of 1200 milliamp-hours, it provides a practical balance between operational duration and physical size, making it suitable for a range of smaller-scale hobby applications. The compact rectangular form factor, measuring just 15mm in width, 36mm in height, and 70mm in length, is engineered to fit into the constrained battery compartments typical of 1/18 and 1/14 scale remote control models. Supplied as a single ready-to-use unit, it serves as a direct power source replacement or upgrade for compatible RC setups.

Features and Construction

This battery pack is built around a 2S LiPo configuration, meaning two lithium polymer cells are connected in series to achieve the specified 7.4-volt output. This voltage is a standard requirement for many entry-level and mid-range brushed and brushless motor systems used in RC modelling.

Material and Build

The core consists of lithium polymer cells, known for their high energy density relative to older battery technologies like NiMH. The cells are housed within a protective wrap or case, typically made from a durable polymer material, which insulates the cells and provides a degree of physical protection. The pack includes wiring and a connector (type not specified) suitable for interfacing with standard RC electronic speed controllers (ESCs).

Size and Practical Fit

The stated dimensions of 15mm wide by 36mm tall by 70mm long define a slim, rectangular profile. This size is particularly relevant for modellers, as it determines compatibility with a model's battery tray or compartment. This battery is likely intended for smaller-scale vehicles, such as 1/18 scale buggies or 1/14 scale trucks, where space is at a premium. Always verify the internal space in your specific model before purchase.

Uses and Placement

This battery is designed as a general-purpose power source within the RC hobby sector, primarily for land and water-based models.

Event or Professional Use

For casual racing or bashing sessions, the 1200mAh capacity offers a sensible runtime for shorter heats or practice runs, potentially reducing the number of battery swaps needed during an event day. Its compact size can be an advantage in classes with strict weight or size distributions, or for models where a low centre of gravity is beneficial.

Everyday Home Use

For the home enthusiast running their model in a garden, park, or on water, this battery provides a straightforward power solution. The 7.4V output is compatible with many ready-to-run (RTR) models and aftermarket electronics. It is suitable for powering both the drive motor and, through the model's BEC (Battery Eliminator Circuit), the steering and throttle servos.

Benefits and Buying Value

The value of this battery lies in its specification-matched design for common RC applications and its direct replacement capability.

Reuse and Low Maintenance

Like all LiPo batteries, this unit is rechargeable hundreds of times with proper care, representing a move away from disposable battery solutions. Maintaining it involves using a compatible LiPo charger, storing it at a safe voltage (typically 3.8V per cell for storage), and avoiding physical damage to the cells or wiring.

Why Choose This Product

This battery is a practical choice for RC modellers seeking a specific 7.4V, 1200mAh power source in a known compact size. It eliminates the guesswork regarding voltage and physical fit for models designed around these parameters. When your model's manual or existing electronics specify a 2S 7.4V battery, this pack provides a matched solution without requiring series/parallel wiring of individual cells.
