Key Features

• Li-Ion Chemistry — This advanced battery technology offers superior energy density compared to older NiCd or NiMH batteries, meaning you get more power in a lighter package, which directly improves your RC model's acceleration, handling characteristics, and overall runtime during play sessions.
• 7.4V Output — The 2-cell series (2S) configuration provides optimal voltage for a wide variety of RC vehicles and hobby electronics, delivering strong torque and speed characteristics without requiring complex charging or balancing procedures beyond standard Li-Ion practices.
• 1500mAh Capacity — This generous capacity ensures extended play sessions and runtime, so you can enjoy longer bashing periods or trail driving adventures before needing to return to your charger, making it excellent value for casual RC users.
• Tamiya Plug Connector — The industry-standard Tamiya connector ensures plug-and-play compatibility with thousands of RC models, eliminating the need for soldering, adapter cables, or specialist knowledge to get your model running immediately.
• XH Balance Connector — The dedicated XH balance lead allows for safe and straightforward charging with compatible Li-Ion chargers, helping maintain optimal cell health and extending the overall lifespan of your battery through proper voltage balancing.
• Compact Lightweight Design — At just 96 grams with dimensions of only 73 x 37 x 19mm, this battery is engineered for models where weight distribution and chassis space are critical factors that affect handling and performance.
• Low Self-Discharge Rate — Unlike older battery chemistries, Li-Ion technology maintains charge retention for extended periods, meaning your battery stays ready to use even if you haven't used your RC model for several weeks.
• 11.1 Watt-Hours Energy — This specification represents the total energy storage capacity, providing a clear indicator of the battery's ability to sustain performance throughout extended RC sessions.

Technical Performance

The Voltz 7.4V 1500mAh Li-Ion battery represents a significant advancement in RC power delivery technology. The lightweight construction at just 96 grams means minimal impact on your RC model's centre of gravity and handling characteristics, which is particularly important for trail driving and technical courses where weight distribution affects steering response and traction. The 11.1 watt-hours energy specification translates to reliable, consistent power delivery throughout the discharge cycle, with Li-Ion chemistry providing superior performance stability compared to earlier battery technologies commonly found in budget RC setups across the UK market. The dual connector system—Tamiya plug for power delivery and XH balance connector for charging—demonstrates professional engineering standards and ensures compatibility with modern chargers and RC models. This battery is constructed to deliver its full 1500mAh capacity reliably across hundreds of charge cycles when properly maintained, making it an economical long-term investment for regular RC users. The soft case packaging protects internal cells from physical damage whilst maintaining minimal bulk, and the compact footprint of 73 x 37 x 19mm allows installation in tight battery compartments found in many popular RC models including FTX Ravine, FTX Buzzsaw, and Heng Long Tug Boat platforms.

Frequently Asked Questions

• What RC models are compatible with this 7.4V 1500mAh battery? — This battery is specifically recommended for FTX Ravine, FTX Buzzsaw, and Heng Long Tug Boat models. However, compatibility extends to any RC vehicle fitted with a Tamiya connector and designed to accept 2S (7.4V) Li-Ion batteries. Always verify your model's battery compartment dimensions against the 73 x 37 x 19mm specifications before purchasing.
• Is this battery suitable for beginners to the RC hobby? — Absolutely. The plug-and-play Tamiya connector means beginners can install this battery without soldering or technical modifications. The Li-Ion chemistry is safer and more straightforward to charge than older technologies, and the 1500mAh capacity provides adequate runtime for learning and casual enjoyment without the complexity of high-performance racing setups.
• How do I charge this Li-Ion battery safely? — Use a charger equipped with dedicated Li-Ion charging capabilities and an XH connector port. The XH balance connector should be connected to your charger's balance socket to ensure all cells charge to identical voltage levels, maximising battery lifespan and safety. Never attempt to charge Li-Ion batteries with chargers designed for older NiCd or NiMH technology.
• What is the runtime I can expect from this battery? — Runtime varies significantly based on your RC model's motor power, driving style, and terrain. Typical casual bashing sessions provide 15-30 minutes of continuous operation, though trail driving and lighter use can extend runtime considerably. Keep a spare battery charged for extended play sessions at the track or field.
• How long does this battery take to charge? — Charge time depends on your charger's output current. With a standard 1A charger, expect approximately 90-120 minutes for a full charge. Higher-output chargers can reduce this time proportionally, though charging at moderate rates helps maximise battery lifespan.
• What makes Li-Ion technology superior to older battery chemistries? — Li-Ion batteries offer higher energy density, meaning more power in less weight, combined with dramatically lower self-discharge rates, superior voltage stability throughout the discharge cycle, and longer overall lifespan when properly maintained. They represent the current standard in modern RC hobby applications across the UK.
• How should I store this battery when not in use? — Store the battery in a cool, dry location at room temperature. For extended storage beyond one month, store with approximately 50% charge remaining to preserve long-term cell health. Periodically check that the battery maintains charge retention and recharge every few months even during inactive periods.
• What is the difference between the Tamiya connector and the XH balance connector? — The Tamiya connector carries the main discharge current to power your RC model's motor and electronic systems. The XH balance connector serves exclusively as a charge port, allowing your charger to monitor and balance individual cell voltages, which is essential for safe Li-Ion charging and maintaining optimal battery health.
