Technical Performance

The Overlander 6250mAh 14.8V 4S 35C Supersport Pro represents a careful engineering balance between capacity, voltage, and discharge capability. At 14.8 volts, the 4S configuration places this battery in the upper-mid range of recreational and competitive RC use, suitable for models ranging from racing buggies and monster trucks to aerial platforms and high-speed boats. The 6250mAh capacity is substantial without being excessively heavy, making it practical for applications where weight matters but extended runtime is essential. The 35C continuous discharge rate translates to a maximum continuous current output of approximately 218.75 amps (6.25A × 35C), providing ample power for brushless motors, ESCs rated for high current draw, and the sustained acceleration demands of modern RC models. The Traxxas connector is gold-plated and designed with low internal resistance, ensuring minimal voltage sag during peak current draw and maximising the battery's usable energy. Whether you're running a competitive 1/10 scale buggy or off-road truck on the track, bashing through natural terrain in a 1/8 scale short course truck, or piloting an aerial multirotor or fixed-wing aircraft, this battery delivers the consistent, reliable power that serious RC enthusiasts expect. The Supersport Pro range is built to withstand multiple charge cycles and the thermal stress of high-discharge applications, making this an investment in long-term performance rather than a disposable component.

Frequently Asked Questions

• What does the 6250mAh capacity mean for my run time? — The 6250mAh capacity provides significantly longer run times compared to smaller packs. For RC cars, you'll enjoy extended sessions on the track or off-road trails; for aircraft and boats, runs remain consistent and uninterrupted throughout longer play sessions. Actual run time depends on your model's motor size, ESC settings, and driving style, but generally expect 15-45 minutes of use depending on the application.
• Is the 14.8V 4S voltage suitable for my RC model? — The 14.8V 4S configuration is ideal for larger RC models or those designed specifically for higher voltage. Check your model's manual or specifications to confirm it supports 4S LiPo voltage. If your model is rated for 2S or 3S only, using a 4S battery may damage the ESC and motor. Most competitive 1/10 and 1/8 scale vehicles, high-performance RC boats, and aerial platforms operate safely on 4S power.
• What is the 35C discharge rate and why does it matter? — The 35C rating indicates the maximum safe continuous current the battery can supply. This translates to approximately 218.75 amps of continuous output (6.25A × 35C). A higher discharge rate means the battery can handle more demanding applications without overheating or failing, making it suitable for brushless motors, high-performance racing, and extreme driving conditions. This ensures your motor receives the power it needs during acceleration, stunts, and climbing demanding terrain.
• Why is the Traxxas connector important? — The Traxxas connector is an industry-standard interface that provides secure, low-resistance connections. Gold-plated contacts minimise voltage drop and energy loss, ensuring maximum power transfer from the battery to your ESC and motor. A secure connection also reduces the risk of disconnection during use, which is critical for safety and performance in competitive and recreational RC applications.
• Can I use this battery in my RC car, plane, boat and helicopter? — Yes, this battery's 4S configuration and high capacity make it suitable across multiple RC disciplines, including RC cars, planes, helicopters, and boats, provided your specific model is rated for 14.8V 4S power. Always consult your model's manual to confirm compatibility before using a new battery.
• What charger do I need for a 4S LiPo battery? — You'll need a dedicated LiPo charger capable of charging 4S lithium polymer batteries, such as a multi-cell charger with 4S balance-charging capability. Many popular UK RC chargers like those from IMAX, SkyRC, and Hitec support 4S charging. Avoid using chargers not specifically designed for LiPo batteries, as they risk damaging the battery or creating safety hazards.
• How long does a 4S LiPo battery take to charge? — Charging time depends on your charger's output current and the battery's capacity. A typical charge at 1C (6.25 amps) would take approximately one hour. Slower charging rates increase the time but can improve battery longevity. Always use a quality charger with LiPo-specific programming and balance-charge capability.
• Is the Overlander Supersport Pro suitable for beginners? — Whilst this is a high-quality, reliable battery, LiPo battery management requires care and responsibility. Beginners should ensure they understand safe charging practices, storage requirements, and voltage monitoring before using a 4S LiPo. If you're new to RC and haven't used LiPo batteries before, consider starting with a smaller pack or seeking guidance from experienced RC enthusiasts at your local club.
• How should I store the Overlander 6250mAh battery? — Store LiPo batteries in a cool, dry location away from direct sunlight and heat sources. The optimal storage voltage for long-term storage is approximately 3.85V per cell (15.4V for a 4S pack). If you won't be using the battery for extended periods, consider charging it to storage voltage and keeping it in a fireproof LiPo storage bag as a safety precaution.
