Key Features

• 5300mAh High Capacity — This generous capacity ensures extended run times during RC bashing sessions, allowing you to spend more time on track or in the field without frequent battery swaps. The larger energy storage means you can tackle longer courses and more demanding driving scenarios without performance degradation.
• 100C Discharge Rate — The exceptional 100C rating provides massive sustained discharge capability, delivering the high amperage required for rapid acceleration, instant throttle response, and consistent power delivery even under maximum load. This rating ensures your RC car UK experience includes snappy, responsive handling at all speed ranges.
• G-Tech Balance Connector — The modern G-Tech balance connector is specifically designed for neat installation, fitting inside vehicle fairings and securing via the supplied thick 12-gauge power leads. This connector design eliminates cable clutter and allows for safe, reliable cell balancing during charging.
• EC5 Main Discharge Connector — The EC5 plug standard provides a secure, low-resistance connection to your vehicle's power system, minimising voltage drop and ensuring maximum energy transfer to your motor and ESC. The robust connector is rated for high-current applications, delivering the power your brushless system demands.
• Thick 12-Gauge Power Cables — Heavy-duty 12-gauge power leads minimise voltage drop during high-drain conditions, ensuring full power reaches your motor at all times. These robust cables also provide structural support, holding the G-Tech balance connector securely in place within the battery bay.
• Compact Dimensions (138 x 46 x 25mm) — Engineered to fit into tight battery slots, this battery pack maximises capacity without requiring chassis modifications. The precise dimensions ensure compatibility with popular ready-to-run RC vehicles whilst providing ample power for serious bashing.
• Lightweight Construction (279g) — Weighing just 279 grams, this battery delivers exceptional power-to-weight ratio, supporting lively performance and agile handling characteristics. The light weight contributes to improved acceleration and reduced strain on your vehicle's drivetrain.
• 2S LiPo (7.4V) Configuration — The two-cell series arrangement provides 7.4V nominal voltage, offering the ideal balance between power output and component compatibility for 1/10 and 1/4 scale RC cars. This voltage rating is suitable for standard brushless ESC systems and motor configurations across the RC hobby.
• Bashing Series Design Philosophy — Unlike racing batteries, Gens Ace's Bashing series prioritises durability, capacity, and robust discharge capability over weight optimisation. This means you get a battery engineered to withstand the demands of aggressive off-road driving and bash-style operation.
• Proven Losi Promoto Compatibility — This battery is specifically tested and confirmed compatible with the Losi 1/4 Promoto-MX Motorcycle RTR, a popular and demanding platform that benefits from this high-capacity, high-discharge solution. Once fitted, the pack sits securely without movement, even during aggressive cornering and jumps.

Technical Performance

This Gens Ace G-Tech battery represents serious engineering focused on delivering consistent, reliable power for demanding RC car bashing scenarios. The 100C discharge rating is a key performance indicator, translating to a maximum continuous discharge capability of 530 amps (5300mAh × 100C). This exceptional rating ensures your brushless motor and ESC receive the full amperage they require, whether you're executing rapid acceleration runs, powering through technical terrain, or sustaining high-speed circuits. The 7.4V nominal voltage (rising to approximately 8.4V when fully charged) provides sufficient power for popular 100A+ brushless ESC systems and high-KV motor combinations commonly found in competitive 1/10 and 1/4 scale platforms. The thick 12-gauge power leads minimise resistive losses during high-current discharge, maximising energy transfer efficiency and ensuring your vehicle responds instantly to throttle inputs. The durable construction, featuring a soft case with protective wrapping, balances durability with weight efficiency. The G-Tech balance connector allows for safe cell balancing during charge cycles, maintaining battery health and extending lifespan. For UK RC enthusiasts running serious brushless setups, this battery delivers the thermal stability and discharge consistency needed for extended sessions without voltage sag or performance drop-off.

Frequently Asked Questions

• What RC models is the Gens Ace G-Tech 5300mAh battery compatible with? — This battery is specifically designed and tested for the Losi 1/4 Promoto-MX Motorcycle RTR, where it fits securely in the battery bay. It is also suitable for other 1/10 and 1/4 scale RC cars that accept 2S LiPo batteries with EC5 connectors, including various ARRMA models. Always verify that your vehicle's ESC is rated for 100C discharge before installation, and confirm connector compatibility with your specific RC platform.
• Is the Gens Ace G-Tech 5300mAh battery suitable for beginners? — This battery is designed for experienced RC enthusiasts rather than newcomers. The high 100C discharge rate demands respect and proper handling. Beginners should start with lower capacity, lower discharge-rate batteries and gradually progress to high-performance packs. However, if you own a Promoto or other high-performance platform, this battery delivers the power those vehicles are designed to use.
• Why does this battery have a 100C discharge rating? — The 100C rating ensures your battery can supply the massive amperage that powerful brushless motors and high-current ESC systems demand during aggressive acceleration, high-speed running, and technical bashing scenarios. A lower C-rating would bottleneck your vehicle's performance through voltage sag and reduced power delivery. The 100C capability unlocks the full potential of brushless platforms.
• How does the G-Tech balance connector differ from standard connectors? — The G-Tech connector is engineered for compact installation, allowing the balance lead to tuck inside vehicle fairings and remain secured by the thick power cables. This design minimises visible wiring clutter and ensures the connector won't snag during impacts or rough handling. Standard connectors often protrude awkwardly, creating potential hazards and cluttering the battery bay.
• What charger do I need for this Gens Ace battery? — You'll need a LiPo-compatible charger capable of 2S operation with balance charging capability. The battery features a dedicated G-Tech balance connector that should be plugged into your charger's balance port during charging to maintain cell health. Proper balance charging extends battery lifespan significantly and prevents dangerous cell imbalances.
• How long will this battery last per charge? — Runtime depends entirely on your driving style, vehicle setup, and motor/ESC configuration. The 5300mAh capacity provides substantial run time compared to smaller batteries. Aggressive bashing and high-speed running will consume the charge faster than casual park driving. Most users can expect 20–40 minutes of active driving, depending on conditions.
• Is this a hard case or soft case battery? — This is a soft case LiPo battery pack, offering lighter weight compared to hard case alternatives whilst still providing adequate protection during normal use. Soft cases are suitable for most bashers. If you require maximum impact protection or plan to transport the battery frequently, hard case options are available from Gens Ace.
• Can I use this battery in series with another 2S pack? — Combining LiPo batteries in series is possible but requires careful attention to safety protocols and matching of discharge rates, remaining charge, and cell voltages. This is an advanced technique beyond the scope of standard RC operation. Most bashers use single battery packs without series combinations.
