Key Features

• Advanced Cell Stacking Technology — Gens Ace's proprietary stacking technology enables single cell capacities of 4000mAh, allowing the manufacturer to pack more energy into a compact footprint. This means you get extended flight times without the weight penalty of larger battery packs, a critical advantage for helicopter pilots in the UK who demand both runtime and agility.
• 45C Continuous Discharge Rating — The 45C continuous discharge capability means this battery can safely and reliably deliver consistent power during sustained high-performance flying. This rating ensures your RC model receives stable voltage throughout your entire flight mission, preventing the voltage sag that can compromise control and responsiveness.
• 90C Burst Discharge Capability — Beyond the 45C continuous rating, the G-Tech battery supports a 90C burst discharge rate, providing explosive power when you execute sharp climbs, rapid acceleration or aggressive aerobatic manoeuvres. This dual-rating system gives you the best of both worlds: sustained performance and peak power on demand.
• Low Internal Resistance (Low IR) — The battery's low internal resistance provides stable voltage until the end of your mission, meaning your RC helicopter or model maintains consistent performance even as the battery depletes. You won't experience the gradual performance degradation common with inferior batteries, keeping your flights smooth and predictable throughout.
• EC5 Connector — The robust EC5 connector provides a secure, low-resistance interface between battery and model. This professional-grade connector minimises connection resistance, reducing heat generation and maximising energy transfer efficiency. You'll experience cleaner power delivery and longer runtimes compared to inferior connector types.
• 6S1P Configuration (22.2V Nominal) — The 6-cell series, 1-cell parallel configuration delivers 22.2V nominal voltage, ideal for high-powered RC helicopters and demanding electric RC models. This voltage level provides the performance envelope that competitive pilots and serious hobbyists require.
• Compact, Lightweight Design — Weighing approximately 644g with dimensions of 160 x 47 x 41mm, this battery delivers serious power in a surprisingly compact package. The weight-to-capacity ratio is optimised for aircraft balance and performance, ensuring your RC helicopter maintains proper weight distribution and flight characteristics.
• High Energy Density — The G-Tech series is specifically adapted to deliver very high energy density according to capacity-to-weight ratio. This engineering excellence means more usable energy per gram, translating directly to longer flight times and better performance for your RC model.
• Flexible Charge Rate Options — The battery recommends 1-3C charge rates for optimal longevity, with a maximum charge rate of 5C. This flexibility allows you to balance between fast charging convenience and battery lifespan, giving you control over your charging workflow.
• International Safety Certification — Gens Ace and its manufacturing partners fulfil ISO9001 and ISO14001 standards, guaranteeing that this battery meets international quality and environmental safety requirements. You're purchasing a product built to genuinely professional standards.

Technical Performance

The GENSACE G-Tech 6S 22.2V 4000mAh 45C battery represents the pinnacle of LiPo battery engineering for demanding RC applications. With a maximum continuous discharge rating of 45C and burst capability reaching 90C, this battery delivers the power characteristics needed for high-performance RC helicopters, particularly models like the Goblin Heli 500 and Goblin Heli 570 that demand responsive, consistent power delivery. The 4000mAh capacity provides meaningful flight runtime whilst maintaining the weight profile required for helicopter balance and agility. At approximately 644g, the battery's energy density is exceptional, with the manufacturer identifying this as particularly high relative to capacity and weight—crucial metrics for any RC pilot concerned with flight performance and endurance.

The engineering excellence behind this battery extends to its internal resistance characteristics. The low IR (internal resistance) design ensures stable voltage delivery throughout your flight mission, preventing the voltage sag that can transform otherwise responsive control inputs into sluggish, unpredictable behaviour. This stability is particularly important in helicopter applications where precision control response is paramount. The EC5 connector specification further enhances performance by minimising connection resistance, ensuring maximum energy transfer from the battery to your motor and ESC system. The 6S1P cell configuration (six cells in series, one cell in parallel) delivers the 22.2V nominal voltage that high-performance RC models require, whilst the single-parallel design keeps the pack lean and flight-ready.

For UK-based RC enthusiasts, this battery excels in both warm summer conditions and cooler autumn and spring flying seasons. The advanced cell stacking technology enables reliable performance across typical UK weather conditions, and the manufacturer's specification of 1-3C recommended charge rates (with 5C maximum) allows flexibility in your charging routine without compromising battery longevity. Whether you're flying at your local RC airfield, practicing aerobatic sequences, or competing in RC helicopter events throughout the UK, the G-Tech battery delivers the consistent, responsive power that separates competitive flying from casual recreation.

Frequently Asked Questions

• Is the GENSACE G-Tech 6S 4000mAh 45C battery suitable for beginner helicopter pilots? — This is a professional-grade battery designed for experienced RC pilots who understand LiPo battery handling, charging procedures and safety protocols. Beginners should start with smaller capacity, lower discharge rate batteries under supervision. However, once you've gained experience and are ready to upgrade to high-performance flying, the G-Tech battery is an excellent investment.
• What RC helicopters is this G-Tech battery compatible with? — The manufacturer specifically recommends this battery for Goblin Heli 500 and Goblin Heli 570 helicopters. It's also suitable for other high-performance RC helicopters, drones and RC aircraft that accept 6S 22.2V LiPo batteries with EC5 connectors. Always verify your specific model's voltage and connector compatibility before purchasing.
• How long does the G-Tech battery take to charge? — At the recommended 1-3C charge rate, a full charge from empty takes approximately 20-40 minutes, depending on your charger's specifications and the selected charge rate. At the maximum 5C rate, charging time reduces to approximately 12 minutes, though this may reduce overall battery lifespan. Most UK RC pilots favour the middle ground of 2-3C charging for balance between convenience and longevity.
• What is the difference between the 45C continuous rating and the 90C burst rating? — The 45C continuous discharge rating indicates the maximum safe current this battery can deliver continuously throughout your flight without overheating or degrading performance. The 90C burst rating indicates the maximum current the battery can handle for short periods during aggressive manoeuvres like rapid climbs or hard acceleration. The dual-rating system gives you sustained performance for extended flight missions plus peak power when you need it.
• Is the EC5 connector standard for 6S RC batteries in the UK? — The EC5 connector is a professional-standard connector used across many high-performance RC applications. Before purchasing, verify that your RC model features an EC5 connector or that you're prepared to use an adapter. Many serious RC enthusiasts in the UK prefer EC5 connectors for their low-resistance characteristics and secure connection.
• How should I store the G-Tech battery when not in use? — LiPo batteries should be stored in a fireproof container at room temperature, ideally in a partially discharged state (around 50% charge) if storing for extended periods. Always store away from flammable materials and moisture. Many UK RC pilots use dedicated LiPo storage safes or metal ammunition boxes. Never leave a LiPo battery unattended while charging.
• What is the weight of the G-Tech 6S 4000mAh battery? — The battery weighs approximately 644g, which is optimised for helicopter balance and performance. This weight-to-capacity ratio ensures your RC model maintains proper weight distribution without excessive battery mass that would compromise agility and responsiveness.
