Key Features

• Large-capacity 8000mAh design — This substantial capacity is specifically engineered to maximise battery life and extend your driving sessions significantly compared to smaller-capacity alternatives, giving you more time on track per charge cycle.
• 100C discharge rating — The high 100C continuous discharge capability means this battery can deliver explosive power output to meet the demanding current draw of high-performance brushless RC motors and ESCs, ensuring snappy acceleration and consistent power delivery throughout your session.
• 4S2P configuration (14.8V nominal) — The 4-cell parallel configuration provides 14.8V nominal voltage, perfectly matched to ARRMA 8S vehicles and other 4S-compatible RC cars, delivering the performance envelope these platforms were designed for.
• Specialised ARRMA vehicle design — This battery has been specifically designed and optimised for use in ARRMA 8S platforms including the Kraton and Outcast, with considerations for fit, weight distribution, and performance characteristics unique to these vehicles.
• Improved battery tray grip — The design features enhanced grip characteristics in the battery tray, ensuring the pack remains secure during aggressive driving, jumps, and rough terrain bashings without shifting or moving within the chassis.
• Dual-protection case construction — The battery features a polycarbonate (PC) outer case combined with silicon rubber protection, providing robust physical protection against impacts, abrasions, and the rigours of off-road RC driving whilst remaining lightweight.
• EC5 discharge connector — The industry-standard EC5 plug ensures compatibility with most modern RC chargers, ESCs, and accessories available in the UK market, eliminating the need for connector adapters.
• JST-XHR balance connector — The standard JST-XHR balance plug allows safe and accurate cell balancing during charging, maintaining cell health and extending overall battery lifespan.
• Low internal resistance (Low IR) — Gens Ace's advanced cell technology delivers stable voltage output until the end of your mission, preventing the voltage sag that can diminish performance in the final minutes of a drive session.
• Stable simultaneous discharge capability — The battery's advanced internal structure allows multiple cells to discharge stably at the same rate, ensuring even cell voltage levels and maximising performance consistency throughout the pack's discharge cycle.

Technical Performance

The Gens Ace G-Tech 8000mAh battery represents state-of-the-art LiPo technology optimised specifically for high-performance RC bashing applications. With a 100C discharge rating, this battery delivers the sustained power output required by modern brushless RC motors and high-current ESCs without excessive voltage sag. The 14.8V nominal voltage from the 4S2P cell configuration positions it perfectly for ARRMA 8S vehicles, which have been engineered from the ground up to utilise this voltage range for optimal performance. Weighing 738-740g (depending on measurement variation), the battery provides excellent energy density relative to its weight, a critical consideration for RC vehicle performance and handling characteristics. The 157mm length, 55mm width, and 42mm height dimensions are specifically engineered to fit snugly in ARRMA 8S battery trays whilst providing optimal weight distribution for vehicle balance. The polycarbonate case with silicon rubber protection offers dual-layer defence against the inevitable impacts and abrasions that come with serious off-road RC driving and bashing sessions. Gens Ace's proprietary low-IR cell technology ensures that voltage remains stable throughout your driving session, preventing the performance degradation that occurs with lower-quality batteries as they discharge. This technical approach means you maintain consistent acceleration, responsiveness, and overall performance from the moment you start driving until the battery reaches its safe discharge threshold. The battery's advanced construction allows the cells to discharge stably and simultaneously, which is essential for vehicles drawing very high current from multiple cells at once.

Frequently Asked Questions

• Will this battery fit my ARRMA 8S Kraton or Outcast? — Yes, absolutely. This battery is specifically designed for ARRMA 8S vehicles including the Kraton and Outcast. The dimensions of 157mm x 55mm x 42mm and the improved battery tray grip design ensure a secure fit with better handling characteristics in these vehicles.
• How long will this battery last per charge in real driving? — Runtime depends on your driving style, vehicle setup, and terrain, but the large 8000mAh capacity provides significantly extended run times compared to smaller-capacity batteries. Expect substantially longer sessions than with 5000mAh or 6000mAh alternatives, though exact duration varies based on motor KV rating, ESC programming, and throttle usage patterns.
• Is this suitable for competitive racing or just casual bashing? — The Gens Ace G-Tech is purpose-built for high-performance bashing applications, but the 100C rating and stable voltage characteristics make it equally suitable for competitive racing where consistent power delivery is crucial. Many UK RC competitors choose Gens Ace batteries for their reliability and performance consistency.
• What charger do I need for this battery? — You need a LiPo charger with EC5 connector compatibility or an EC5 adapter for your existing charger. The battery features a JST-XHR balance connector, so your charger must also support this connector type for safe cell balancing. Most modern RC chargers available in the UK market support both connectors.
• What makes the 100C discharge rating important? — The 100C rating indicates the maximum continuous current the battery can safely deliver. For an 8000mAh battery, this means it can safely provide up to 800A continuous current. High-performance brushless motors and ESCs in ARRMA 8S vehicles draw very high currents, especially during acceleration, so the 100C rating ensures the battery can meet these demands without excessive voltage sag or heat generation.
• How does the dual-protection case benefit my battery? — The polycarbonate outer shell provides hard impact protection against drops and crashes, whilst the silicon rubber layer provides cushioning and vibration damping. Together, these materials protect your battery from physical damage that could compromise cell integrity or cause dangerous internal short circuits.
• Will this battery work with Traxxas X-MAXX or other non-ARRMA vehicles? — Whilst the battery's 4S 14.8V specification makes it compatible with any vehicle designed for 4S LiPo batteries, the 157mm length is too long for many battery trays, particularly in Traxxas vehicles like the X-MAXX. Always verify the battery dimensions against your vehicle's battery tray specifications before purchasing.
• How often should I charge this battery and what are the safety considerations? — Charge the battery after each use or before storing it for extended periods. Always use a quality LiPo charger with balance charging capability, never leave a charging battery unattended, and store the battery in a cool, dry location in a LiPo safety bag. Never discharge the battery below 3.0V per cell (12.0V total for a 4S pack) as this can cause permanent damage.
• Is there a warranty on this battery? — Gens Ace provides a 1-year warranty on this battery, covering manufacturing defects and failures. Extended discounts and support are available for purchases beyond the initial year. Contact us for warranty support and registration details.
• How does this compare to other 4S LiPo batteries available in the UK? — The Gens Ace G-Tech distinguishes itself through the specialised ARRMA vehicle design, the high 100C discharge rating, proven low-IR technology for stable voltage characteristics, and the dual-protection case construction. These features combine to deliver exceptional performance and durability compared to generic 4S batteries. The G-Tech branding indicates this is a premium product within Gens Ace's range, positioned above their standard offerings.
