Key Features

• 7.4V Li-Ion Chemistry — The two-cell lithium-ion configuration delivers a nominal voltage of 7.4V, providing consistent power delivery throughout your run without the voltage sag associated with older battery chemistries, ensuring your RC vehicle maintains responsive performance from start to finish.
• 1500mAh Capacity — This 1500 milliamp-hour capacity offers a sweet spot between weight and runtime, giving you plenty of energy for extended bashing and trail-driving sessions without adding unnecessary weight to your RC model that could affect handling and speed.
• Mini Tamiya Plug Connector — The industry-standard Mini Tamiya plug means immediate compatibility with a wide range of RC vehicles, including the FTX Ravine and FTX Buzzsaw, requiring no soldering or adapter modifications — simply unplug and swap out your old battery for fresh power in seconds.
• XH Balance Connector — The included XH balance lead allows you to perform balanced charging, which monitors each individual cell within the battery pack and ensures they charge evenly, maximising battery lifespan and maintaining safe operating conditions for every charge cycle.
• Low Self-Discharge — Li-Ion batteries naturally exhibit minimal self-discharge compared to older battery technologies, meaning your fully charged battery will retain its charge for longer periods when stored, keeping your RC car ready to run at a moment's notice without the need for constant pre-run top-ups.
• Lightweight and Compact Design — Weighing just 96 grams with dimensions of 73 x 37 x 19mm, this battery fits easily into tight battery bays found in modern RC vehicles, maximising interior space for other components whilst keeping overall weight down for optimal performance and handling characteristics.
• Soft Case Construction — The flexible soft case protects your battery from impacts and abrasions during transport and storage without the weight penalty of a rigid plastic shell, making it perfect for keeping in your pit bag or RC kit for convenient portability.

Technical Performance

The Voltz Li-Ion 7.4V 1500mAh battery represents solid engineering and reliable power delivery for RC enthusiasts. With a nominal voltage of 7.4V (two 3.7V cells in series) and a capacity of 1500mAh, this pack generates 11.1 watt-hours of total energy storage. The lithium-ion chemistry has been engineered to provide efficient energy delivery with low internal resistance, ensuring minimal voltage sag even under moderate load conditions. This characteristic means your RC vehicle will maintain responsive throttle control and consistent performance throughout your run, rather than experiencing the gradual power loss that occurs with degraded battery packs. The battery's compact footprint of 73 x 37 x 19mm and modest weight of 96 grams makes it an excellent fit for medium-sized RC models, particularly the FTX range of ready-to-run vehicles. The inclusion of both the Mini Tamiya main connector and XH balance connector demonstrates attention to proper charging protocols — balanced charging is essential for maintaining cell voltage equilibrium and ensuring safe operation. The soft case provides adequate protection during normal use and transport, protecting the cells from physical damage whilst remaining flexible enough to fit into the battery compartments of most compatible models. This battery is particularly well-suited to everyday bashing and trail-driving applications where consistent, reliable power is more important than chasing maximum speed figures.

Frequently Asked Questions

• Is the Voltz 7.4V 1500mAh battery suitable for beginners? — Absolutely. This battery is an excellent choice for RC beginners because it offers straightforward plug-and-play compatibility with popular ready-to-run models like the FTX Ravine and FTX Buzzsaw. The Mini Tamiya connector is universally recognised, and the included XH balance lead makes safe charging simple. There's no soldering required, and the modest capacity means it's forgiving if charging mistakes are made. For anyone new to RC who wants a reliable spare battery without the complexity of LiPo management, this is an ideal choice.
• What RC models is this battery compatible with? — This battery is specifically recommended for the FTX Ravine and FTX Buzzsaw models. However, any RC vehicle that accepts a 7.4V power source with a Mini Tamiya plug connector will be compatible. That includes many entry-level RC cars, RC crawlers, and small RC trucks from various manufacturers. Always check your vehicle's manual to confirm the correct voltage and connector type before purchasing.
• Can I use this battery with a standard charger? — Yes, the XH balance connector allows you to use any charger that supports XH balance leads, which includes most modern chargers specifically designed for lithium-ion batteries. Balanced charging is the recommended method as it ensures each cell charges evenly and maintains the battery's health. Never attempt to charge this battery with a charger designed for older nickel-cadmium or nickel-metal hydride batteries, as lithium-ion packs require specific charging profiles.
• How long does this battery last on a single charge? — Runtime depends on several factors including the weight and power demands of your specific RC model, driving style, and terrain. However, for a typical 1/10 scale RC car like the FTX Ravine running on moderate terrain, you can expect 20-40 minutes of continuous running per charge. Aggressive driving or running uphill will reduce runtime, whilst gentle trail driving will extend it.
• What makes Li-Ion better than LiPo for RC use? — Lithium-ion batteries offer several advantages over LiPo chemistry: they have lower self-discharge rates, meaning the battery retains its charge for longer periods between uses; they are generally more robust and forgiving if charging is slightly mismanaged; and they don't require the same level of careful handling that LiPo batteries demand. The trade-off is that Li-Ion typically offers slightly lower peak power output and requires longer charge times. For casual RC use, trail driving, and bashing, Li-Ion is often the better choice.
• Is this battery waterproof or water-resistant? — The soft case provides basic protection against splashes and moisture, which is suitable for light water crossings during trail driving. However, this battery is not fully waterproof and should not be submerged. If you plan to run in wet conditions, always dry the battery thoroughly after use and store it in a dry location. Moisture can compromise the internal circuitry and pose safety risks.
• How should I store this battery when not in use? — Store the battery in a cool, dry place away from direct sunlight and extreme heat. Lithium-ion batteries perform best when stored at room temperature. It's recommended to store the battery at around 50% charge rather than fully charged or fully depleted, as this reduces stress on the cells. The low self-discharge characteristics of Li-Ion mean the battery will maintain its charge for extended periods, making it ideal for keeping as a spare pack in your RC kit.
• Can I use this battery with a high-speed RC car or RC buggy? — This battery is designed for moderate-performance applications and everyday use. Whilst it will power compatible models, it may not be the optimal choice for competition-level racing or high-speed bashing where maximum burst power is required. The 1500mAh capacity and Li-Ion chemistry provide steady, reliable power rather than peak power output. For high-performance applications, many users prefer LiPo batteries with higher discharge rates (higher C ratings). Always check your vehicle's manual for recommended battery specifications.
