The G-Tech series represents Gens Ace's commitment to advanced battery technology, combining exceptional energy density with stable voltage delivery throughout your mission.

This 4-cell battery configuration provides the perfect balance of power and weight for intermediate to advanced RC enthusiasts who require genuine performance from their equipment. The 4000mAh capacity offers extended flight and run times, whilst the 60C continuous discharge rating ensures your RC model receives the responsive acceleration and sustained power delivery needed for competitive flying and racing. At RC Model Shop, we stock only genuine Gens Ace batteries, trusted by RC competitors and weekend flyers throughout the United Kingdom and Europe.

The XT60 connector ensures compatibility with the vast majority of modern ESCs and chargers used in the RC hobby, making this an excellent choice whether you're upgrading an existing setup or building a new high-performance RC model from scratch. Gens Ace batteries are engineered with low internal resistance (Low IR technology), which means you'll experience stable voltage output right up to the end of your flight or run, delivering consistent performance when it matters most.

Key Features

• 60C Continuous Discharge Rating — This high discharge rate means the battery can deliver sustained power to demanding motors and ESCs without voltage sag, ensuring your RC car, plane or drone maintains peak performance throughout your entire flight or racing session.
• 4000mAh Capacity — The generous 4000mAh capacity provides extended runtime compared to smaller battery packs, allowing you to enjoy longer flights in your RC plane or more competitive laps in your RC car before needing to recharge.
• 4-Cell 14.8V Configuration — The 4S (4-cell) design delivers the high voltage output required for high-powered brushless motors, making this ideal for high-speed RC cars, performance FPV planes, and multi-rotor drones that demand serious power.
• XT60 Connector — The industry-standard XT60 connector is compatible with virtually all modern RC chargers, ESCs and battery trays, ensuring hassle-free integration with your existing RC equipment and infrastructure.
• Low IR (Internal Resistance) Technology — Gens Ace's Low IR design means minimal voltage drop during discharge, so you'll maintain stable voltage output right until the battery needs recharging, delivering consistent power for the entire duration of your RC session.
• Soft Case Protection — The battery arrives in a protective soft case that shields it from damage during transport and storage, and can be reused to safely carry and store your battery between flights or races.
• Advanced Energy Density — Gens Ace specialises in high-power lithium polymer technology with exceptional energy density adapted specifically to RC aircraft, quadcopters, hexacopters and RC vehicle applications, maximising performance whilst keeping weight to a minimum.
• Stable Simultaneous Discharge Technology — Gens Ace batteries are engineered to discharge stably even when multiple packs are used simultaneously, ideal for operations requiring parallel battery configurations in large-scale RC models.
• ISO Certified Manufacturing — Every Gens Ace G-Tech battery is manufactured under strict ISO9001 and ISO14001 quality and environmental standards, ensuring consistent quality, reliability and safety in every pack.

Technical Performance

The Gens Ace G-Tech 4S 14.8V 4000mAh 60C represents the pinnacle of lithium polymer battery engineering for discerning RC hobbyists in the UK. With a continuous discharge rating of 60C and a burst capability of 120C (2x the continuous rating), this battery delivers explosive power for high-acceleration launches, aggressive cornering, and full-throttle performance in competitive RC environments. The 4000mAh capacity strikes an excellent balance between weight and endurance, providing sufficient energy storage for extended flights in RC planes and FPV wings, while remaining light enough for responsive handling in high-performance RC cars and trucks. Measuring 162mm in length, 45mm in width and 26mm in height, the battery fits within the battery compartments of most modern RC models, though you should always verify dimensional compatibility with your specific vehicle before purchase. At 405g, the weight is carefully engineered to provide maximum energy storage without adding unnecessary mass that would compromise acceleration and agility. The XT60 connector is gold-plated for excellent conductivity and minimal resistance, reducing heat generation during high-current discharge and ensuring your RC equipment operates at peak efficiency. The soft case construction protects the battery during transport and casual storage, though for serious competitors or those flying in challenging weather, additional protective cases are recommended. The manufacturer specifies a recommended charge rate of 1-3C, which on a 4000mAh pack means optimal charging between 4 and 12 amps, allowing you to recharge fully in approximately 20 minutes to an hour depending on your charger and chosen charge rate. This battery has been specifically engineered for FPV planes, wings, quadcopters, hexacopters and similar UAV applications, but also performs excellently in high-performance RC cars, boats and helicopters where sustained power delivery is critical.

Frequently Asked Questions

• Is the Gens Ace G-Tech 4000mAh battery suitable for my RC plane or FPV drone? — Yes, this battery is specifically designed for FPV planes, wings, quadcopters and hexacopters. The 4S configuration provides the voltage required for modern brushless flight controllers and high-performance motors, whilst the 4000mAh capacity offers excellent runtime for extended flights. Always verify compatibility with your specific aircraft's battery compartment dimensions and weight limitations before purchase.
• What is the difference between the 60C continuous and 120C burst rating? — The 60C continuous discharge rating means the battery can safely deliver 60 times its capacity (240 amps in this case) on a sustained basis without damage. The 120C burst rating (achieved during peak acceleration or aggressive manoeuvres) represents double the continuous rating and is available for short periods. This dual-rating system ensures you get maximum performance whilst maintaining battery safety and longevity.
• How long does the Gens Ace G-Tech battery take to charge? — At the manufacturer's recommended 1-3C charge rate, this 4000mAh battery will charge in approximately 20 minutes to an hour depending on your charger amperage. At 1C (4 amps) it takes roughly one hour, whilst at 3C (12 amps) it takes around 20 minutes. Always use a balance charger capable of charging 4S LiPo batteries safely.
• What is Low IR technology and why does it matter for my RC model? — Low IR (Internal Resistance) technology means the battery has minimal voltage drop during discharge, maintaining stable output voltage right until the battery needs recharging. This translates to consistent power delivery throughout your entire flight or racing session, ensuring your RC car maintains top speed or your RC plane maintains stable control right up to the end of the battery's charge cycle.
• Is this battery compatible with standard RC chargers available in the UK? — The XT60 connector is the industry standard on virtually all modern RC chargers and ESCs available in the UK. However, you must use a charger specifically capable of charging 4S (4-cell) LiPo batteries with balance charging capability. A standard 2S or 3S charger will not work with this 4S battery.
• How should I store the Gens Ace G-Tech battery when not in use? — Store the battery in the included soft case in a cool, dry location away from direct sunlight and heat sources. For storage periods exceeding one month, it is recommended to discharge the battery to approximately 50% capacity (around 3.7V per cell) to maximise long-term cell health and lifespan.
• What makes Gens Ace batteries different from cheaper alternatives? — Gens Ace batteries feature advanced engineering including Low IR technology for stable voltage, high energy density adapted to specific RC applications, simultaneous stable discharge capability, and ISO certified manufacturing ensuring consistent quality. Gens Ace is a recognised specialist in high-power lithium polymer technology with discharge ratings reaching up to 100C, making them ideal for serious RC competitors and demanding applications.
