• 4S Configuration (14.8V) — The 4-cell series configuration delivers 14.8V nominal voltage, making this battery compatible with a huge range of modern RC cars, trucks and bashers that accept 4S LiPo power sources.
• 60C Continuous Discharge Rating — The 60C rating means this battery can deliver sustained high current output, providing the rapid acceleration and responsive power delivery that competitive RC drivers demand, whether on road or off-road courses.
• XT90 Connector — The industry-standard XT90 discharge connector offers a secure, reliable connection with excellent contact reliability and minimal voltage drop, ensuring your power delivery remains uncompromised during intense driving sessions.
• Hard Case Protection — Unlike soft-case batteries, this pack is housed in a protective hard case that safeguards the cells during transport, storage and in-vehicle mounting, extending battery lifespan and protecting your investment.
• G-Tech 5P Balance Connector — The proprietary G-Tech 5-pin balance connector allows for precise cell-level charging and monitoring, ensuring each of the four cells charges evenly and maintains optimal performance across the pack's lifespan.
• Low Internal Resistance (IR) — Engineered with low internal resistance technology, this battery maintains stable voltage output right until the end of your run, ensuring consistent power delivery and preventing the performance sag that comes with high IR batteries.
• Compact, Practical Dimensions — At 138mm length, 46mm width and 49mm height, this battery is designed to fit in the battery bays of most modern 4S RC cars and trucks, including larger platforms like the Traxxas X-Maxx when positioned sideways.
• Lightweight at 588g — The 588g weight represents an excellent energy density, providing substantial capacity without excessive weight that would compromise your vehicle's handling characteristics and acceleration.
• Bashing Series Engineering — Part of Gens Ace's dedicated Bashing Series, this battery is specifically engineered to handle the demands of off-road bashing, high-impact driving and rough terrain, not just smooth circuit racing.
• ISO9001 & ISO14001 Certified Manufacturing — Every battery is manufactured to strict international quality and environmental standards, meaning you can rely on consistent, safe performance with every charge cycle.
• Simultaneous Stable Discharge Technology — Gens Ace's unique technology allows these batteries to discharge stably simultaneously across multiple cells, maintaining voltage balance and preventing cell damage during demanding applications.

Technical Performance

The Gens Ace G-Tech 7000mAh 60C 4S battery pack represents a significant step forward in LiPo performance for demanding RC car applications. The engineering philosophy behind this battery focuses on delivering very high energy density specifically adapted to RC car and truck platforms. With a continuous discharge rating of 60C, this battery is capable of delivering up to 420 amps of continuous current (7Ah × 60C), making it suitable for high-performance electric RC cars that demand rapid acceleration and sustained speed. The 14.8V nominal voltage of the 4S configuration is the standard for high-power RC car racing and bashing, providing the voltage sweet spot between performance and component compatibility. The weight of 588 grams is extremely well-balanced against the 7000mAh capacity, giving you excellent power-to-weight ratio that won't significantly impact your vehicle's handling or acceleration characteristics. The hard case construction ensures durability during the rough-and-tumble world of RC car bashing, protecting the individual lithium polymer cells from impact, puncture and environmental damage. Gens Ace's proprietary low internal resistance technology means this battery maintains voltage stability right through your driving session, preventing the voltage sag that lesser batteries suffer as they discharge. The G-Tech 5P balance connector allows for precise cell-level monitoring, enabling your charger to ensure each of the four cells charges to exactly the same voltage, maximising battery longevity and maintaining consistent performance across all charging cycles. This is a battery engineered by specialists who have dedicated their technology to high-power applications, with the maximum capability of their technology reaching 100C discharge ratings, so the 60C version represents proven, reliable engineering rather than experimental technology.

Frequently Asked Questions

• Will the Gens Ace G-Tech 7000mAh 60C 4S battery fit in my Traxxas X-Maxx? — Yes, this battery will fit in a Traxxas X-Maxx, though it will need to be positioned sideways with the connectors running along the side rather than towards the top of the battery bay. This is a practical solution for larger RC vehicles that require substantial power.
• What vehicles is this 4S LiPo battery compatible with? — This 14.8V 4S battery is designed for RC cars and trucks that accept 4S LiPo power sources with XT90 connectors. Compatibility includes modern RC racing buggies, bashers, short-course trucks, and truggy platforms with battery bays that can accommodate dimensions of approximately 138 × 46 × 49mm. Always verify your specific vehicle's battery specifications before purchasing.
• How long does the battery last on a single charge? — Runtime depends on your vehicle's motor, ESC settings and driving style. With a 7000mAh capacity, you can expect substantial run time on most RC cars, though high-performance applications with higher discharge rates will naturally consume the capacity more quickly than casual driving.
• What is the difference between this G-Tech battery and other Gens Ace models? — The G-Tech series is part of Gens Ace's Bashing Series, specifically engineered to handle the impacts and demands of off-road RC car bashing. The combination of the hard protective case, 60C discharge rating, and low internal resistance technology makes this particularly suited to demanding applications compared to lower-rated alternatives.
• What type of charger do I need for this battery? — This battery features a G-Tech 5P balance connector, so you'll need a charger compatible with this connector type for balanced charging. Many quality LiPo chargers sold in the UK market support multiple connector types, though you should always verify compatibility before purchasing a charger.
• How should I store this battery? — Store the battery in the protective hard case provided, in a cool, dry location. For long-term storage beyond a few weeks, partially discharge the battery to approximately 50% capacity (around 7.4V for a 4S pack) as this is the optimal storage state for lithium polymer cells.
• Why does this battery have such a high discharge rating? — The 60C discharge rating indicates how much current the battery can safely deliver continuously. High-performance RC cars demand rapid acceleration and sustained speed, requiring batteries that can deliver substantial current without overheating or losing voltage stability. This rating ensures the battery can handle your vehicle's demands safely.
• Is this suitable for beginners? — This is a high-performance battery designed for drivers who understand LiPo battery safety and maintenance requirements. Beginners should ensure they have an appropriate charger, understand the basics of LiPo care, and follow all safety guidelines. If you're new to RC cars and LiPo batteries, we recommend speaking with our knowledgeable team at RC Model Shop before purchasing.
