Key Features

• High-Voltage Chemistry (HV) — This battery utilises high-voltage LiPo chemistry, which delivers increased cell voltage compared to standard lithium polymer cells, resulting in more aggressive acceleration and higher peak power output for your RC car throughout the entire discharge cycle.
• Extreme 140C Discharge Rating — The 140C continuous discharge rate provides massive burst power and sustained high-current delivery, making this pack suitable for high-performance ESCs and demanding racing applications where peak power is critical for competitive edge.
• 5200mAh Capacity — This generous capacity ensures extended running times between charges, allowing you to enjoy longer sessions on the track or at the bash spot without frequent battery swaps, whilst maintaining consistent voltage under load.
• Durable Hard Case Format (RL2) — The rigid hard case protection safeguards your battery cells from punctures, crushing and damage during transport, storage and pit use, which is particularly valuable during organised events and track days where equipment handling can be rough.
• Factory-Installed 5.0mm Bullet Connector — The standard 5mm bullet connector system is pre-soldered and tested at the factory, ensuring reliable electrical connections and compatibility with most RC car ESCs and receivers available in the UK market.
• Stable Automatic Stacking Technology — Gens Ace's proprietary single-cell stacking process enables consistent 5200mAh capacity per cell, with strict matching of individual cell capacity, voltage and discharge curves to ensure balanced pack performance throughout the lifespan of the battery.
• Rigorous Quality Control — Every cell undergoes the most strict capacity, voltage, resistance and discharge curve matching process during manufacturing, guaranteeing that you receive a perfectly balanced 2S pack with minimal cell variance.
• Low Internal Resistance (Low IR) — The pack's optimised internal resistance design provides stable voltage delivery until the end of your mission, preventing the power sag that can compromise handling and performance in the final stages of a run.
• Lightweight Performance — At approximately 200g, this battery delivers exceptional power-to-weight ratio, ensuring minimal impact on your RC car's handling characteristics and acceleration whilst providing the energy needed for competitive racing.

Technical Performance

The Gens Ace Li-Po HV Car Hard Case represents the pinnacle of performance battery engineering for RC car applications. With a 140C discharge rating, this pack is engineered to deliver extreme burst power and sustained high-current performance, making it ideal for brushless RC cars equipped with high-performance ESCs capable of handling continuous currents in excess of 700A (5200mAh × 140C). The high-voltage chemistry means each cell operates at slightly elevated voltage, contributing to the pack's aggressive power characteristics and making it particularly effective for acceleration-focused racing applications. The 7.6V nominal voltage across the 2S1P configuration makes this pack compatible with virtually all modern brushless ESC systems designed for 2S operation, from racing-focused equipment to general-purpose speed controllers.

Engineering excellence is evident throughout the pack's construction. The hard case housing is manufactured to protect the delicate LiPo cells from the impacts and stresses encountered during normal RC car use, pit transport and competitive events. The factory-installed 5.0mm bullet connector system is engineered for optimal conductivity and repeated connection cycles, ensuring your battery performs reliably across multiple models and racing seasons. Gens Ace's manufacturing process incorporates automatic cell stacking technology that delivers single-cell capacities of exactly 5200mAh, with every cell matched across capacity, voltage, resistance and discharge curve characteristics. This meticulous quality control process ensures your pack delivers balanced performance across both cells throughout the entire discharge cycle, preventing the premature cell cutoff and performance degradation that can occur with poorly matched battery packs. The pack's low internal resistance design ensures stable voltage maintenance throughout your running session, preventing the voltage sag that can dramatically impact handling and reduce competitive performance in the critical final minutes of racing.

Frequently Asked Questions

• Is the Gens Ace 5200mAh 140C battery suitable for competitive RC car racing in the UK? — Yes, this battery is specifically designed for high-performance RC car applications. The 140C discharge rating provides the burst power and sustained current delivery needed for competitive racing, whilst the strict cell matching ensures consistent performance throughout a race run. The hard case format also provides protection important for organised events where equipment handling can be demanding.
• What RC car models is this 2S LiPo battery compatible with? — This 2S pack is suitable for most modern brushless RC cars designed for 2S operation, including models from Xray, Yokomo, Awesomatrix, Team Associated and TLR. Compatibility depends on your ESC's voltage rating and connector type. The factory-installed 5.0mm bullet connector is standard on most performance RC car ESCs, making this pack compatible with the majority of racing-oriented vehicles available in the UK market.
• What are the key differences between this Gens Ace HV battery and standard LiPo packs? — This battery utilises high-voltage (HV) chemistry, which delivers increased cell voltage compared to standard LiPo cells, resulting in more aggressive acceleration and higher peak power output. The 140C discharge rating is significantly higher than many standard batteries, providing extreme burst power for competitive applications. The hard case format offers superior protection compared to soft pouches, making this particularly valuable for competitive use and transport between events.
• How should I care for and store this hard case LiPo battery? — Store the battery in the hard case at room temperature in a dry location, away from direct sunlight. For extended storage periods (more than a month), charge the battery to storage voltage (around 3.8V per cell, or 7.6V for this 2S pack) to preserve cell health. Always inspect the battery visually before use and never use a battery that shows swelling, damage or discoloration. The hard case provides excellent protection during normal use and transport.
• What charger do I need for this 2S battery? — You'll need a LiPo-compatible battery charger capable of balanced charging for 2S packs. The charger should support 2S LiPo profiles and ideally feature cell balancing capability. Most modern RC chargers sold in the UK support 2S LiPo charging, and many can handle the 5200mAh capacity without difficulty. Balance charging ensures both cells remain perfectly matched in voltage, maintaining optimal performance and battery longevity.
• Is this battery safe for beginner RC car drivers? — Whilst this battery is robust and reliable, LiPo batteries in general require proper handling, storage and charging procedures. Beginners should familiarise themselves with LiPo safety best practices, including proper charging procedures, safe storage in the hard case, and avoiding over-discharge. Always follow manufacturer guidelines and your charger's instructions carefully. The hard case format does provide excellent physical protection compared to soft pouches, making inadvertent damage less likely during handling.
