Key Features

• 8.4V NiMH Chemistry — This battery uses proven nickel-metal hydride technology, which is inherently safer than lithium-based alternatives, easier to charge without specialist equipment, and offers excellent cycle life so you can enjoy hundreds of charge-discharge cycles without degradation. NiMH batteries are perfect for casual bashers and racers who prioritise reliability and straightforward maintenance over cutting-edge performance.
• 3300mAh Capacity — The 3300mAh capacity provides solid runtime for general RC use, delivering sufficient charge to keep your RC car, truck or buggy running through extended play sessions whilst remaining light enough not to compromise handling or balance. This capacity is a sweet spot for most 1/10 scale vehicles and smaller 1/8 scale models.
• T-Type Deans Connector — The T-Type connector, commonly known as the Deans connector in the RC community, is one of the most widely used and recognised battery connectors in the hobby. This connector provides secure, low-resistance connections that minimise voltage drop and ensure maximum power delivery to your ESC and motor system. The gold-plated contacts resist corrosion and maintain conductivity over time, even with frequent connect-disconnect cycles.
• Compact Hump-Pack Design — At just 134mm in length and 397g in weight, this battery is specifically designed to fit hump-pack mounting points found on many RC buggies, trucks and stadium cars. The hump configuration allows for optimal weight distribution and centre of gravity placement, which is crucial for balanced handling and predictable cornering behaviour on both tarmac and off-road surfaces.
• Practical Dimensions for Easy Installation — With a width of 46mm and height of 42mm alongside the 134mm length, this pack fits snugly into purpose-designed battery compartments without requiring modification or creative mounting solutions. The manageable 397g weight ensures your RC model maintains appropriate mass distribution without tipping the scales excessively, allowing you to comply with class weight limits if you're competing in organised racing events.
• Gens Ace Quality and Reliability — Gens Ace is a globally recognised battery manufacturer trusted by professional racers, enthusiasts and commercial RC operators worldwide. Every battery undergoes rigorous quality control testing before it leaves the factory, ensuring consistent performance and longevity. When you choose Gens Ace, you're choosing a brand with a proven track record of delivering reliable, safe power solutions.

Technical Performance

The Gens Ace NiMH 8.4V Hump 3300mAh battery represents solid engineering designed specifically for the needs of RC enthusiasts who demand dependable performance without complications. The 8.4V nominal voltage provides sufficient potential to drive most standard brushed and brushless motors found in 1/10 scale RC cars, trucks, and buggies, delivering power levels that balance speed with runtime. NiMH chemistry delivers consistent voltage throughout the discharge cycle, which means your RC model maintains relatively stable performance rather than experiencing the voltage sag characteristic of heavily discharged LiPo packs. The 3300mAh capacity stores enough energy for meaningful play sessions whilst the hump-pack form factor ensures seamless integration into vehicles designed with centre-mounted battery bays. The Deans T-Type connector uses high-quality gold-plated contacts that provide exceptionally low-resistance connections, minimising power loss and heat generation during high-current draw situations. The 397g weight is deliberately moderate, ensuring that the battery contributes appropriately to your RC model's overall mass without making the vehicle sluggish or unresponsive. NiMH batteries are inherently robust and forgiving, capable of handling overcharging and deep discharges better than lithium alternatives, making them genuinely beginner-friendly whilst remaining perfectly suitable for experienced bashers and racers who appreciate the straightforward nature of the chemistry.

Frequently Asked Questions

• Is the Gens Ace NiMH 8.4V Hump 3300mAh suitable for beginners? — Absolutely. NiMH batteries are genuinely beginner-friendly because they're forgiving with charging errors, don't require specialist monitoring equipment, and offer excellent safety characteristics compared to lithium alternatives. You can charge this battery on any standard NiMH charger without worrying about overcharging or fire risks. The straightforward technology means you can focus on enjoying your RC hobby rather than managing complex battery chemistry.
• What vehicles is this battery compatible with? — This battery is designed for RC cars, trucks, buggies and other models that feature a hump-pack battery mounting point and T-Type Deans connector. Most 1/10 scale electric RC vehicles and many smaller 1/8 scale models accept this form factor. You should verify that your specific RC model has a hump-pack battery bay and Deans connector before purchasing. RC Model Shop staff can help you confirm compatibility if you're unsure.
• How long will the battery last on a single charge? — Runtime depends on your specific RC model's motor system, driving style, and terrain. Generally speaking, the 3300mAh capacity will deliver 15-30 minutes of continuous running on most standard 1/10 scale electric RC cars and trucks, though actual duration varies considerably based on motor KV rating, ESC throttle settings, and whether you're racing competitively or casual bashing. More powerful motors and aggressive driving will consume the charge faster than relaxed cruising.
• Can I use this battery with LiPo chargers? — No, you should not use a LiPo-specific charger with this NiMH battery. NiMH packs require dedicated NiMH chargers that use different charging algorithms and safety protocols. Using the wrong charger type can damage the battery or create safety hazards. Invest in a proper NiMH charger to ensure safe, reliable charging every time.
• How does NiMH compare to LiPo batteries for RC use? — NiMH batteries are safer, more forgiving with charging mistakes, require no specialist balance chargers, and can handle overcharging and deep discharges without risk. LiPo packs offer higher power density and better performance for racing applications, but require more careful management and specialist charging equipment. For casual bashers, beginners, and anyone prioritising simplicity and safety, NiMH remains an excellent choice. For competitive racing where maximum speed matters, LiPo dominates, but for pure enjoyment and reliability, NiMH delivers genuine value.
• What's the difference between this hump pack and a stick pack configuration? — Hump packs are specifically designed to sit in the centre of your RC model's chassis using a hump-style mounting point, whilst stick packs are longer and thinner, designed to mount in compartments that run lengthways along the chassis. The hump configuration offers superior weight distribution and lower centre of gravity for improved handling, making it the preferred choice for most modern RC buggies, trucks and cars.
• How many charge cycles can I expect from this battery? — NiMH batteries typically deliver 500-1000 complete charge cycles before capacity begins to noticeably decline, making them excellent value for money compared to disposable battery options. With proper care and using a quality NiMH charger, you should enjoy several years of reliable service from this pack.
