7.4V 1200mAh Lithium Battery for Compact RC Model Cars and Boats

This specialised lithium battery pack delivers 7.4V power with a 1200mAh capacity specifically designed for remote control hobby applications. Its slender 15x36x70mm dimensions make it an ideal power source for 1/10 scale model cars, electric boats, and other RC vehicles where space within the battery compartment is limited. The battery provides a practical solution for enthusiasts needing a compact power supply that maintains sufficient capacity for moderate running sessions without requiring frequent recharging during use.

Features and Construction

Built around lithium-ion cell technology, this battery pack is configured to deliver stable 7.4V output compatible with both 2S and 3S power systems commonly found in RC models. The construction focuses on maintaining reliable performance within the constrained physical dimensions, allowing it to serve as either a direct replacement for original equipment or an upgrade for custom builds where standard-sized batteries won't fit.

Material and Build

The battery utilises lithium-ion cells arranged to provide the specified 7.4V output voltage. This chemistry offers a favourable balance between energy density and discharge characteristics for RC applications, supporting the power demands of electric motors in model cars and boats. The external casing is designed to protect the cells while maintaining the minimal 15mm width that enables installation in narrow battery trays.

Size and Practical Fit

With measurements of 15mm width, 36mm depth, and 70mm height, this battery's proportions are particularly suited to 1/10 scale remote control vehicles where internal space is at a premium. The 70mm height allows for efficient use of vertical space within compartments, while the 36mm depth provides adequate cell arrangement for the 1200mAh capacity. This dimensional specificity means it will physically fit applications where generic battery packs are too bulky or incorrectly proportioned.

Uses and Placement

This battery is intended primarily for hobbyist remote control applications, particularly scale model cars and electric boats operating on 2S or 3S power systems. Its voltage and capacity specifications make it suitable for moderate-performance vehicles rather than extreme racing applications, positioning it as a reliable power source for recreational use and casual competition where consistent runtime is valued over maximum power output.

Event or Professional Use

For organised RC events or club meetings, this battery provides sufficient capacity for multiple practice sessions or qualifying rounds without requiring intermediate recharging. The 1200mAh rating offers a practical balance between weight and endurance, making it suitable for drivers who need predictable performance throughout an event day. Its compact size can be advantageous in classes with strict technical regulations regarding battery dimensions.

Everyday Home Use

For home use and backyard running, the battery delivers enough power for extended play sessions while remaining easy to handle and install. The 7.4V output is compatible with many entry-level and intermediate RC models, making it a versatile option for enthusiasts with multiple vehicles. Its slender profile allows it to fit in models with narrow battery compartments that cannot accommodate wider standard packs.

Benefits and Buying Value

This battery offers a targeted solution for RC enthusiasts facing space constraints in their models. Rather than modifying vehicle chassis or battery trays to accommodate generic power supplies, this pack provides dimensions specifically suited to tight installations. The 1200mAh capacity represents a practical middle ground between minimal runtime batteries and larger capacity options that might not physically fit constrained spaces.

Reuse and Low Maintenance

As a lithium battery, it supports multiple charge cycles with proper care, providing long-term value through repeated use across different RC sessions. The standard voltage output means it can serve as a universal replacement for original equipment batteries in compatible models, extending the usable life of RC vehicles when original power supplies are no longer available or have degraded over time.

Why Choose This Product

This battery addresses a specific dimensional requirement within the RC hobby space—providing adequate power in a form factor that fits where standard batteries cannot. For modellers working with 1/10 scale cars, small boats, or other compact electric models, finding a power source that balances capacity with physical constraints can be challenging. This product offers that balance with its 1200mAh capacity contained within 15x36x70mm dimensions, making it a logical choice when compartment space dictates battery selection.
