Key Features

• 3300mAh Capacity — The 3300mAh capacity provides substantial runtime for your RC model, allowing extended play sessions before you need to recharge, which is particularly valuable if you're running multiple batteries in rotation or want to maximise your time on the track or field.
• 8.4V Nominal Voltage — This voltage specification (typically representing 7 cells in NiMH chemistry) is a standard power level for many RC applications, delivering adequate performance for general RC use whilst maintaining the safety advantages of NiMH battery chemistry compared to lithium alternatives.
• T-Type Connector — The T-Type plug ensures a reliable, secure connection that's widely used across the RC hobby, providing consistent electrical contact and compatibility with models designed around this connector standard, eliminating compatibility headaches.
• Flat Pack Form Factor — The deliberately engineered flat profile allows this battery to fit neatly into compact battery compartments found in many RC vehicles, maximising space efficiency and allowing you to maintain proper vehicle weight distribution.
• Lightweight at 397g — Weighing just 397 grams, this battery contributes minimal added weight to your RC model, which is critical for maintaining responsive handling and maximising acceleration and speed performance.
• Compact Dimensions — At 156mm length, 46mm width and 24mm height, this battery packs significant capacity into a genuinely compact footprint that fits where bulkier battery packs simply won't, making it ideal for models with space constraints.
• NiMH Chemistry Safety — NiMH batteries are inherently safer than lithium chemistries, requiring less complex charging infrastructure and offering superior tolerance to physical abuse, over-discharge and temperature extremes, making them perfect for recreational RC use.
• Gens Ace Quality Assurance — Built to Gens Ace's exacting standards, this battery undergoes rigorous quality testing to ensure consistent performance, cell matching and longevity, giving you peace of mind that your investment will deliver reliable power session after session.

Technical Performance

The GENSACE NiMH 8.4V Flat 3300mAh battery represents a carefully optimised balance between capacity, weight and form factor. At 397 grams, this battery remains light enough to avoid adversely affecting your RC model's handling characteristics, whilst the 3300mAh capacity ensures you'll enjoy extended runtimes typical of quality NiMH packs. The flat configuration measures just 156mm long, 46mm wide and 24mm high, engineered specifically to squeeze into the compact battery bays found in modern RC vehicles without requiring bulky external battery boxes. The T-Type connector is a industry-standard plug type that ensures positive connection with minimal contact resistance, critical for maintaining stable voltage delivery under the dynamic current demands of RC motoring. NiMH battery chemistry, whilst perhaps lacking the energy density of modern LiPo cells, provides superior safety characteristics including tolerance to physical damage, resistance to over-discharge conditions, and compatibility with basic chargers that don't require expensive battery management systems. This makes NiMH technology particularly popular for recreational RC use and ideal for users who prioritise simplicity and safety alongside performance. The 8.4V nominal voltage (typically representing seven NiMH cells) delivers ample power for general RC applications from casual backyard running to competitive club racing depending on your specific vehicle's motor and ESC specifications. Build quality throughout reflects Gens Ace's reputation for meticulous cell matching and construction, with internally balanced cells ensuring consistent voltage delivery throughout the discharge cycle.

Frequently Asked Questions

• What RC vehicles is this 8.4V NiMH battery compatible with? — This battery is suitable for any RC application designed to accept an 8.4V NiMH flat pack with a T-Type connector, including various RC cars, buggies, trucks and crawlers from manufacturers offering models with this battery specification. Before installation, always verify that your vehicle's specifications match: 8.4V voltage compatibility, T-Type connector, and sufficient internal space for a battery measuring 156mm long, 46mm wide and 24mm high. Consult your vehicle's instruction manual to confirm compatibility.
• How long will this battery last per charge? — Runtime depends on your specific RC model, driving style, motor size, ESC settings and terrain. Larger motors and higher throttle demand will reduce runtime, whilst conservative driving can extend it. Typically, users report 30 minutes to well over an hour of continuous running, making this 3300mAh capacity excellent for recreational use without excessive charging downtime.
• Is NiMH better than LiPo for my RC hobby? — NiMH and LiPo represent different trade-offs. NiMH batteries like this Gens Ace pack offer superior safety (no risk of fire or thermal runaway), tolerance to abuse, simpler charging infrastructure and lower cost, making them ideal for recreational users, beginners and anyone prioritising simplicity. LiPo batteries offer higher energy density, lighter weight and superior power delivery, preferred by competitive racers. For general UK RC hobby use, NiMH remains an excellent, user-friendly choice.
• What charger do I need for this battery? — NiMH batteries require an NiMH-compatible charger capable of delivering appropriate current to the 8.4V pack. Standard chargers often have selectable NiMH and NiCd settings. Avoid using LiPo-only chargers (these lack the necessary NiMH charging algorithm) or discharging through RC vehicle ESCs unless your ESC specifically supports NiMH battery management. A basic NiMH charger is typically very affordable and suitable for this battery.
• How does the T-Type connector differ from other connector types? — The T-Type connector is simply one of several standard plugs used in RC applications. Other common types include Deans, XT60 and Tamiya connectors. T-Type offers reliable connection with good current capacity suitable for general RC use. If your RC vehicle uses a different connector type, you'll need an appropriate adapter cable or will need to replace the connector (which requires soldering skills).
• Is this battery suitable for beginners? — Absolutely. This Gens Ace 8.4V NiMH battery is excellent for beginners because NiMH chemistry offers inherent safety advantages, the charging process is straightforward, and there's no risk of the catastrophic failure modes associated with lithium batteries if mishandled. The flat form factor fits many ready-to-run RC vehicles, making this an ideal choice for anyone just discovering the RC hobby.
• What weight does this battery add to my RC model? — At 397 grams, this battery contributes moderate weight. For context, smaller capacity NiMH packs weigh proportionally less but provide shorter runtime, whilst larger capacity packs weigh more. The 3300mAh capacity represents a sensible sweet spot, and the flat design minimises impact on vehicle weight distribution. Always check your vehicle manual's recommended battery weight range to ensure proper vehicle dynamics.
• How long does this battery take to charge? — Charging time depends on your charger's output current and the NiMH charging algorithm. A typical 1A charger might require 3-4 hours for a full charge, whilst higher-current chargers (2A or more) can complete charging in 1-2 hours. Always follow your charger manufacturer's instructions and never leave batteries unattended during charging.
• Can I use this battery in multiple RC vehicles? — Yes, provided each vehicle uses 8.4V NiMH batteries with T-Type connectors and adequate internal space. Many RC enthusiasts maintain a collection of batteries and rotate them between vehicles, which is an economical approach that maximises hobby enjoyment whilst managing charging time effectively.
