Frequently Asked Questions

• Is the GENSACE G-Tech 11000mAh 100C battery suitable for my ARRMA RC car? — This battery is specifically engineered for ARRMA vehicles and delivers optimal performance in the ARRMA 1/5-scale Kraton 8S. However, it can be used in any RC car with a 4S LiPo battery system, including larger 1/10-scale brushless vehicles. The substantial capacity and high discharge rate make it ideal for high-powered applications, though you should verify your vehicle's battery tray can physically accommodate the 178×51×52mm dimensions before purchasing.
• What does the 100C discharge rating actually mean for my driving experience? — The 100C rating means this battery can safely deliver continuous current equal to 100 times its capacity (11000mAh × 100 = 1,100 amps maximum). In practical driving terms, this exceptional discharge rating ensures your throttle response is immediate and consistent, with virtually zero voltage sag even under maximum acceleration or climbing steep terrain. You'll notice crisp, responsive power delivery throughout the discharge cycle, which is essential for competitive driving and aggressive bashing.
• Can I use this battery with my existing RC charger if I don't have a G-Tech compatible charger? — Absolutely. This battery is universally compatible with any standard RC LiPo charger available in the UK. Simply connect it to your existing charger and programme the parameters manually (4S, 11000mAh, 100C discharge) exactly as you would with any traditional LiPo battery. However, upgrading to a G-Tech compatible charger will unlock the Auto Charge Technology feature, which eliminates manual programming and enhances safety.
• What are the advantages of G-Tech Auto Charge Technology? — When paired with a G-Tech supported charger, the integrated ID chip in this battery's balance connector automatically communicates your battery's exact specifications—voltage, capacity, chemistry and recommended parameters—to the charger. The charger then applies the correct settings automatically. This eliminates the risk of user error during manual programming, which has historically been a significant cause of damaged batteries and charging-related accidents. It's genuinely a step forward in RC battery safety and convenience.
• How long will this battery last during a single driving session? — Runtime depends entirely on your driving style, vehicle efficiency and load. As a general rule, an 11000mAh battery at moderate throttle typically provides 20-30 minutes of driving in a 1/5-scale ARRMA vehicle, though aggressive full-throttle bashing will reduce this to 15-20 minutes. The extended capacity is particularly valuable when you want longer sessions or are running multiple packs throughout a driving day, as this single pack provides significantly more usage time than smaller batteries.
• Is this battery waterproof or suitable for wet conditions? — The polycarbonate and silicone rubber case provides excellent protection against moisture ingress and impacts, making it well-suited for use in wet terrain or rainy conditions common in the UK. However, we always recommend allowing any LiPo battery to dry thoroughly after wet-weather use and storing it in a cool, dry location. The battery pack itself is not sealed against full submersion, so avoid intentionally dunking it in water.
• What makes the EC5 connector better than alternatives like XT60? — The EC5 connector is specifically designed for ultra-high-current applications and features significantly larger contact surfaces compared to XT60 or similar connectors. This results in lower contact resistance, reduced voltage drop during peak current draw, and substantially improved reliability during intense usage. For a battery with 100C discharge capability, the EC5 connector is genuinely the appropriate choice and helps you realise the full performance potential of the pack.
• How should I store this battery between driving sessions? — LiPo batteries are best stored in a cool, dry location at approximately 50% state of charge (around 3.6-3.7V per cell, or roughly 14.4-14.8V for this 4S pack). We recommend storing it in a dedicated LiPo storage bag, which is a small fabric pouch designed to safely contain a battery if any thermal runaway were to occur (though this is extremely rare with quality batteries). Store it away from flammable materials and never leave it in hot vehicles or direct sunlight. Most UK RC enthusiasts maintain several batteries in rotation, charging to storage voltage after each use and leaving them unused until the next driving session.
• What is the difference between this 4S2P pack and a standard 4S1P battery? — This battery uses a 2P (two-pack parallel) configuration, meaning two sets of four cells are connected in parallel rather than a single string. This architecture distributes the current load across more cell paths, resulting in lower heat generation per cell, extended cell lifespan, and improved reliability under extreme discharge rates like the 100C this battery provides. A comparable 4S1P pack would struggle under this discharge rate, whereas the 2P design allows safe delivery of maximum performance throughout the discharge cycle.
• Is this battery suitable for beginners or experienced drivers only? — Experienced RC enthusiasts and competitive bashers will get the most from this battery's exceptional specifications. However, beginners can certainly use it provided their RC vehicle is compatible and they understand basic LiPo safety practices (safe charging, storage in a fire-safe location, awareness of thermal runaway signs). The G-Tech Auto Charge Technology actually makes this battery more beginner-friendly than traditional LiPo packs because it removes dangerous manual programming steps. If you're new to RC and unsure whether your vehicle is compatible, please contact our Walsall store for expert guidance.
• How much does this battery cost to charge compared to smaller alternatives? — The charging cost is proportional to capacity. This 11000mAh pack will cost slightly more to charge than smaller batteries, but it provides significantly extended runtime per charge cycle. Many UK bashers find that using a single larger battery like this is more economical than running multiple smaller packs throughout a driving day, because you're charging less frequently overall. The actual electricity cost is minimal regardless—LiPo charging consumes roughly the same energy as charging a smartphone.
