Key Features

• 4200mAh Capacity — This generous capacity provides extended runtime compared to smaller batteries, allowing you to spend more time driving your RC model before needing to recharge, which is essential for enjoying longer RC sessions at your local track or bash spot.
• 2S LiPo Configuration (7.4V) — The 2S configuration is one of the most common LiPo voltage standards for RC vehicles, offering a perfect balance between power output and vehicle compatibility, and making this battery suitable for a huge range of ready-to-run and competition RC cars available in the UK market.
• 40C Maximum Continuous Discharge Rate — A 40C discharge rating means this battery can safely deliver very high current outputs to your ESC and motor, providing responsive acceleration, strong hill-climbing ability, and consistent power throughout your run without voltage sag or performance loss.
• Round/Oval Stick Pack Format — The distinctive stick pack shape is narrower and longer than a traditional flat pack, allowing it to fit into RC vehicles with tight battery compartments or where a flat rectangular pack simply won't fit, making it an ideal space-saving solution.
• Tamiya Output Connector — Pre-fitted with the Tamiya connector standard, this battery is immediately compatible with any RC vehicle featuring a Tamiya-type receiver port, eliminating the need for adapters or connector soldering and ensuring a secure electrical connection.
• 31.08Wh Energy Capacity — The watt-hour rating tells you the total energy stored in this pack; 31.08Wh represents a significant power reserve that translates to longer driving sessions compared to lower-capacity alternatives, particularly beneficial for competitive racing where runtime can determine race outcomes.
• Hard Case Protection — The durable hard case exterior protects the battery cells during transport, storage, and use, preventing physical damage that could compromise cell integrity, and making it safer to carry in your RC pit bag or toolbox.
• Compact Dimensions — At just 137 x 47 x 25mm, this battery's modest size and light weight make it easy to carry to the track, and the slim profile is specifically engineered to fit RC vehicle designs that specify stick pack batteries as standard.

Technical Performance

The Voltz 4200mAh LiPo battery represents solid engineering and proven reliability in the RC hobby. With a maximum continuous discharge rate of 40C, this battery is engineered to deliver sustained high-current output across the full duration of your run, whether you're driving a brushless RC car at full throttle or navigating technical rock-crawling terrain. The 2S (7.4V) configuration is the sweet spot for countless RC applications; it's not so high that it demands expensive high-voltage electronics, yet it's powerful enough to drive most popular RC vehicles on the market today. The 31.08Wh energy capacity is calculated from the 4200mAh × 7.4V specification and provides approximately 45 minutes to 1 hour of driving time depending on vehicle weight, motor efficiency, and driving style. The hard case construction uses proven materials that protect against short circuits and physical damage, critical for maintaining cell health and ensuring safe operation. Voltz batteries are manufactured to strict quality standards and undergo rigorous testing to ensure they meet advertised specifications. The Tamiya connector is gold-plated and shrouded for safety, providing a secure fit and reliable electrical continuity. This battery is ideal for everything from casual bashing and recreational driving to more serious competitive racing where consistent power delivery directly affects performance and lap times.

Frequently Asked Questions

• Is the Voltz 4200mAh LiPo battery suitable for RC cars and vehicles in the UK? — Yes, absolutely. This 2S 7.4V LiPo battery is compatible with a huge range of RC cars, trucks, buggies, and other radio control vehicles. The 7.4V output is one of the most common standards in the RC hobby, making it ideal for both ready-to-run models and competition platforms. Simply verify that your vehicle's receiver and ESC support 2S LiPo batteries before purchasing.
• What does the 40C discharge rating mean and why does it matter? — The 40C continuous discharge rating indicates this battery can safely deliver up to 168 amps (4.2 × 40) of continuous current. This high discharge rate provides the responsive acceleration and consistent power delivery that RC enthusiasts demand, ensuring your vehicle has plenty of punch whether you're accelerating from standstill, climbing hills, or driving at full throttle on a race track.
• How long will the 4200mAh battery last on a single charge? — Runtime depends heavily on your vehicle's weight, motor efficiency, gearing, and driving style. As a general guide, you can expect 30 to 60 minutes of driving time per charge. For accurate runtime estimates, consult your vehicle's manual or ask the friendly team at RC Model Shop, who can provide specific recommendations based on your exact RC setup.
• Does this battery come with a charger? — No, this is the battery pack only. You will need a dedicated LiPo battery charger compatible with 2S LiPo batteries. Most RC enthusiasts use a multi-chemistry charger such as those made by Hobbywing, iMaxRC, or similar brands. A proper LiPo charger is essential for safe charging and maximising battery lifespan.
• What is the difference between this Voltz stick pack and a flat pack battery? — The main difference is physical shape. The stick pack is longer and narrower, designed to fit into vehicle battery compartments that don't have space for traditional flat rectangular packs. If your RC vehicle specifies a stick pack battery, this Voltz model will fit perfectly. Electrically, both deliver the same voltage and capacity.
• Can I use this battery in any 2S LiPo compatible vehicle? — Provided your vehicle accepts 2S LiPo batteries and features a Tamiya connector, yes. However, always check your vehicle's manual or specifications first. Some smaller vehicles may be rated for lower capacities or discharge rates, so verification is important.
• Is the hard case removable? — The hard case is integrated into the battery design for protection during storage and transport. You should never remove it, as the case provides essential physical protection and contains the cells safely.
• How should I store this battery when not in use? — Store the Voltz battery in a cool, dry place away from direct sunlight and moisture. Ideally, keep it at a partial charge (around 50%) if you're storing it for extended periods. Always store LiPo batteries away from children and pets, and never store them in environments prone to extreme heat.
