Key Features

• 140C Discharge Rating — This exceptional discharge rate provides the high current output needed for high-performance RC cars, enabling rapid acceleration and sustained power delivery throughout your run. Higher discharge rates mean your battery can supply the energy your motor demands without voltage sag, keeping your car responsive and competitive.
• 4400mAh High Capacity — The generous 4400mAh capacity ensures extended run-time, allowing you to spend more time driving and less time charging. This is particularly valuable for racing applications where longer run sessions translate to more practice laps and better track time.
• 7.6V HV (2S) Chemistry — Operating at 7.6 volts with HV (High Voltage) chemistry, this 2S1P configuration delivers more power per cell than standard LiPo batteries, providing superior performance for modern brushless RC motors. The HV chemistry also contributes to higher energy density, crucial for competitive driving.
• Stable Automatic Stacking Technology — Gens Ace employs proprietary automatic stacking technology that enables consistent single cell capacities of 4400mAh. This advanced manufacturing process ensures every cell in the pack performs identically, maximising overall battery reliability and longevity.
• Strict Capacity and Voltage Matching — Each battery undergoes the industry's most rigorous quality control process, including precise matching of single cell capacity, voltage, internal resistance, and discharge curves. This meticulous attention to detail ensures consistent performance and prevents the imbalances that can reduce battery life and reliability.
• Factory-Installed 5.0mm Bullet Connectors — The standard 5.0mm bullet connectors are pre-installed at the factory, providing a solid, reliable electrical connection that minimises contact resistance and ensures maximum power transfer to your RC car's electronics.
• RL2 Shorty Hardcase Format — The compact shorty hardcase design maximises internal space efficiency whilst maintaining structural integrity. This format is ideal for RC cars with tight battery compartments, and the protective hardcase shield protects your battery from impacts and damage during transport and storage.
• Low Internal Resistance (Low IR) — The battery maintains stable voltage throughout your entire mission, providing consistent power delivery until the battery is depleted. Low internal resistance is critical for maintaining peak performance and ensuring your RC car responds predictably from start to finish.
• Exceptional Energy Density — Specially adapted engineering provides very high energy density according to capacity-to-weight ratio. This means you get serious power without excessive weight, crucial for RC car performance where every gram counts toward handling and speed.
• Simultaneous Stable Discharge Technology — Gens Ace's unique technology allows the battery to be discharged stably and simultaneously, making it ideal for high-performance applications where consistent power delivery across multiple discharge events is essential.
• ISO9001 and ISO14001 Certified Manufacturing — Gens Ace and its manufacturing partners maintain strict international quality and environmental standards, ensuring every battery meets the highest safety and production standards in the industry.

Technical Performance

The GENSACE Li-Po HV Car Hard Case represents a significant advancement in RC car battery technology, specifically engineered for the demands of modern high-performance brushless RC vehicles. With dimensions of approximately 96mm length, 47mm width, and 18mm height, this shorty format fits neatly into space-constrained battery compartments common in competitive and casual RC cars. At 164.2 grams, the battery weight is well-optimised for RC car use, providing substantial capacity without creating the kind of weight penalty that would negatively impact handling or acceleration. The 140C discharge rating is exceptional, enabling peak currents of up to 616 amps at full capacity, which is precisely what modern high-KV brushless motors require for rapid acceleration and sustained high-speed running. The 7.6V nominal voltage (providing approximately 8.4V at full charge in HV configuration) delivers the electrical potential required for maximum motor performance whilst remaining compatible with standard 2S battery inputs found on most modern RC car ESCs. The hardcase construction provides essential protection against the bumps, crashes, and storage damage that are inevitable in RC car use. Whether you're racing on asphalt at a local UK RC car club, bashing in the garden, or competing in organised events, this battery provides the power consistency and reliability you can depend on. The combination of high discharge rate, substantial capacity, advanced cell matching, and low internal resistance means you'll experience minimal voltage sag, meaning your RC car will maintain responsive handling and peak acceleration throughout the entire run, translating directly into better lap times and more enjoyable driving.

Frequently Asked Questions

• What is the difference between HV and standard LiPo chemistry? — HV (High Voltage) LiPo cells operate at a higher nominal voltage than standard LiPo cells, typically 3.85V per cell versus 3.7V per cell in standard LiPo. This means a 2S HV pack runs at 7.6V nominal compared to 7.4V for standard 2S, providing approximately 2.7% more power. HV batteries also provide higher energy density and better performance in high-discharge-rate applications, making them ideal for competitive RC cars and high-performance racing.
• Is this battery suitable for beginners? — This is an advanced performance battery designed for experienced RC car enthusiasts and competitive racers rather than complete beginners. The 140C discharge rating and HV chemistry are optimised for high-performance brushless systems. If you're new to RC cars, you may want to start with a standard capacity, lower discharge rate battery before upgrading to this professional-grade pack.
• What is the typical run-time I can expect? — Run-time depends heavily on your specific RC car, motor KV, driving style, and load conditions. The 4400mAh capacity provides substantial run-time for most RC cars, typically ranging from 8-15 minutes of continuous high-performance driving, or longer if driven at moderate throttle. For precise run-time estimates, consult your RC car manufacturer's recommendations for this capacity and discharge rate.
• Will this battery work with my RC car? — This battery is compatible with any RC car featuring a 2S LiPo battery compartment and 5.0mm bullet connector inputs. Verify your RC car accepts 2S HV LiPo batteries and uses standard 5.0mm connectors. The shorty hardcase format is designed to fit compact battery bays common in modern RC cars, but always check your vehicle's battery compartment dimensions (approximately 96 × 47 × 18mm) before purchasing.
• How should I charge this battery? — Use a quality LiPo-compatible charger capable of balancing charging. The 4400mAh capacity and recommended charge current will be specified in your charger's manual. Always follow proper LiPo safety procedures, charge in a fire-safe location, and never leave charging batteries unattended. A balanced charger ensures both cells in the 2S pack charge evenly, maximising battery lifespan and safety.
• What warranty and support does Gens Ace provide? — Gens Ace provides a 1-year warranty on this battery pack, covering manufacturing defects and performance issues under normal use. Extended warranty options and special discounts are available for orders beyond the standard 1-year period. Contact RC Model Shop for warranty claims and support.
• How does the 140C discharge rating compare to other RC car batteries? — The 140C rating is at the very high end of discharge performance, even exceeding the maximum 100C rating that represents Gens Ace's highest power technology benchmark. This makes it suitable for the most demanding high-performance applications, racing setups, and vehicles requiring sustained maximum current draw. For comparison, many casual RC car batteries feature 50-80C discharge rates, making this pack significantly more powerful.
• What makes the automatic stacking technology important? — Gens Ace's stable automatic stacking technology ensures that all individual cells within the battery pack are manufactured to identical specifications. This means each 2200mAh cell maintains the same capacity, voltage, and discharge characteristics, resulting in perfectly balanced performance and extended battery lifespan. Mismatched cells can lead to voltage imbalances, reduced run-time, and accelerated degradation, which automatic stacking technology prevents.
