Technical Performance

The Gens Ace G-Tech 3S LiPo battery represents professional-grade engineering in a compact format suitable for mini-scale RC vehicles. Delivering 11.1 volts across three series-connected cells with a total capacity of 2200mAh, this battery provides approximately 24.42 watt-hours of energy storage. The 35C discharge rating indicates the battery can safely deliver a maximum continuous discharge current of 77 amps (2200mAh × 35C), providing more than sufficient power for aggressive acceleration and sustained high-speed driving on mini-scale buggies and trucks. With a weight of approximately 166 grams and dimensions of 100mm length, 34mm width, and 28mm height, this battery integrates seamlessly into the compact chassis designs of Arrma Grom series vehicles and similar mini-scale platforms. The soft case construction protects the cells from external damage whilst keeping weight to a minimum, essential for maintaining the performance characteristics these vehicles are engineered to deliver. The patented iEC2 connector features gold-plated contacts that resist oxidation and maintain excellent electrical continuity over hundreds of charge and discharge cycles, ensuring long-term reliability. For UK RC car enthusiasts running brushless motor systems in their mini-scale vehicles, this battery offers the stable voltage output and consistent power delivery needed for smooth acceleration and predictable handling characteristics. The low internal resistance of this LiPo pack means minimal voltage drop during peak current draw, translating to more responsive throttle feel and better overall driving experience compared to batteries with higher internal resistance.

Frequently Asked Questions

• Is the Gens Ace G-Tech 3S 2200mAh 35C battery suitable for beginners running mini-scale RC cars? — Yes, this battery is an excellent choice for beginners and experienced drivers alike. The reverse polarity protection built into the iEC2 connector prevents accidental damage from incorrect connection, making it safer than older connector types. The 35C discharge rate is well-suited to brushless motor systems commonly found in modern mini-scale vehicles, and the 2200mAh capacity provides longer run times that help you develop better driving skills without constant battery changes.
• What vehicles is this battery compatible with in the UK market? — This battery is specifically engineered for Arrma Grom 3S BL, small-scale TYPHON GROM Buggy, MOJAVE GROM, Arrma Gorgon GROM, Arrma Quake GROM, and Losi NASCAR platforms. The iEC2 connector is also fully compatible with EC2 and IC2 device connectors, so if you have other mini-scale vehicles using these standard connectors, this battery will work with them as well. Always verify your vehicle's original connector type before purchasing to ensure compatibility.
• How long will the Gens Ace 2200mAh battery last per charge? — Runtime depends on your driving style, motor KV rating, and gearing, but typical mini-scale RC vehicles will achieve 15-25 minutes of continuous driving per fully charged battery. For maximum enjoyment, many UK RC enthusiasts maintain two or more batteries in rotation, allowing them to keep driving while one battery charges.
• What charger do I need for this 3S LiPo battery? — You will need a dedicated LiPo charger capable of charging 3-cell (11.1V) batteries. The charger should have a balance charging function to ensure each of the three cells charges to the same voltage, extending battery lifespan. Never attempt to charge LiPo batteries with standard chargers designed for NiMH or NiCd batteries, as this can damage the pack or cause safety hazards.
• How does the iEC2 connector compare to other connectors used in mini-scale RC vehicles? — The patented iEC2 connector offers key advantages including reverse polarity protection, gold-plated contacts for superior conductivity, and seamless compatibility with EC2 and IC2 connectors. This makes it a more advanced choice than older connector types, reducing the risk of accidental damage from reversed connections whilst maintaining excellent electrical performance.
• What is the difference between this battery and the standard Gens Ace LiPo batteries? — The G-Tech series specifically emphasises compatibility with mini-scale platforms through the patented iEC2 connector, which ensures perfect fit with original vehicle connectors. The G-Tech series also features optimised energy density for the weight constraints of mini-scale vehicles, meaning you get more usable power in a package light enough not to negatively affect vehicle handling characteristics.
• How should I store and maintain this battery for maximum lifespan? — Store the battery in a cool, dry location away from direct sunlight, ideally at a partial charge state (around 50% capacity) if storing for extended periods. Before extended storage, discharge the battery to approximately 3.0 volts per cell (9.0 volts total for this 3S pack). Always inspect the battery before use for any signs of damage, swelling, or leakage. Never store or charge a damaged battery, as LiPo batteries can be a fire hazard if compromised.
