O-GT2S3300-30X9

Technical Performance

The Gens Ace Soaring 3300mAh 2S 7.4V 30C battery represents a carefully engineered balance of capacity, discharge rate and physical dimensions designed specifically for demanding RC applications. With a nominal voltage of 7.4V (two lithium polymer cells in series), this battery suits any RC model designed for 2S LiPo power, from nimble racing buggies to scale-model aircraft. The 30C continuous discharge rating indicates this battery can safely deliver 99 amps of current continuously (3300mAh × 30C = 99A), making it suitable for moderate to high-performance motors without thermal stress or voltage collapse. The integrated G-Tech smart chip represents a generational leap forward in battery technology—rather than simply storing charge, the chip stores complete battery metadata that can be read by compatible chargers, enabling automatic detection of optimal charging parameters and preventing the overcharging, undercharging or imbalanced charging that degrades battery lifespan. The recommended charging rate of 1-3C means safe charging at currents between 3.3 and 9.9 amps, allowing flexibility between rapid charging and conservative trickle-charging depending on your available equipment and time constraints. Weighing approximately 172 grams and measuring 134 x 43 x 13mm, this battery fits within the battery trays and compartments of most medium to large-scale RC cars, helicopters and planes, though users should always verify physical fitment before purchase. The low internal resistance characteristic of quality LiPo cells, combined with Gens Ace's premium manufacturing processes, ensures voltage remains stable under load, delivering consistent power for the entire discharge cycle rather than the voltage sag that renders cheaper batteries sluggish in the final minutes of use. These batteries are manufactured by a company with 20 years of dedicated LiPo expertise and 200 professional engineers focused solely on battery development, guaranteeing the engineering and quality control standards exceed those of budget competitors.

What You Need to Complete

• LiPo-compatible balance charger — A charger capable of balancing 2S LiPo batteries; G-Tech compatible chargers will automatically detect specifications, whilst standard LiPo chargers require manual voltage and capacity entry
• RC model designed for 2S 7.4V LiPo batteries — Verify your RC car, helicopter, plane or boat is compatible with 7.4V before connecting this battery
• Fire-resistant LiPo storage bag — Essential for safe storage between uses, protecting against potential thermal incidents
• XT90 connector adapter (if your RC model uses different connectors) — If your model uses XT60, Deans, EC5 or other connectors, adapters are readily available from UK RC retailers

Frequently Asked Questions

• Is the Gens Ace G-Tech 2S 3300mAh battery suitable for RC car racing in the UK? — Yes, this 30C discharge-rated battery is well-suited for RC cars, particularly larger-scale models and sport/touring vehicles. The 3300mAh capacity provides excellent runtime for club racing and weekend bashing, whilst the XT90 connector ensures reliable power delivery under sustained high current draw. Many UK RC enthusiasts choose this capacity for Traxxas Slash and similar stadium trucks.
• Can I use this battery with my standard RC charger, or do I need a G-Tech charger? — The G-Tech chip and auto-charge technology only function with G-Tech compatible chargers, but the battery's universal balance connector means you can charge it with any standard LiPo-compatible balance charger. You simply won't access the automatic detection benefits—manual programming of 2S, 3300mAh and 1-3C charging rate will be required with conventional chargers.
• What runtime should I expect from the 3300mAh capacity? — Runtime depends entirely on your RC model's power consumption. A lightly-loaded application like a soaring aircraft might run 30-60 minutes, whilst a high-performance racing car with high-draw motor and servo might achieve 15-25 minutes of spirited use. The 30C rating ensures voltage remains stable throughout the discharge cycle, preventing the performance degradation that occurs when cheaper batteries are heavily loaded.
• Is this battery waterproof for RC boat use? — The battery itself is not waterproof—the cells and connectors must be protected from water immersion. For RC boat use, mount the battery in a waterproof battery box or bag before placing in your boat. The XT90 connector is not sealed, so water contact could cause corrosion or electrical hazards. Always protect your battery from water exposure.
• How does the 30C rating compare to other 2S batteries I see in UK RC shops? — The 30C continuous discharge rating is moderate to conservative—you'll find 45C, 60C and 80C rated 2S batteries available, offering higher peak discharge capability. However, 30C is perfectly adequate for most sport-level RC applications, and provides a good balance between capacity, weight, and cost. Select a higher C-rating only if your specific RC model's motor and ESC are designed for higher current draw.
• What safety features protect against overcharging and cell damage? — The G-Tech chip stores balance data and communicates with G-Tech chargers to prevent dangerous overcharging scenarios. Additionally, the recommended 1-3C charging rate range ensures you never charge faster than the cells can safely accept. Always use a reputable LiPo charger with low-voltage cutoff protection, store the battery at safe voltage when not in use, and never leave batteries charging unattended.
• Is this battery suitable for a beginner or first-time RC user? — Yes, absolutely. The 3300mAh capacity provides excellent runtime for learning, reducing frustration from short flight or run times. The G-Tech auto-charge technology actually makes this battery more beginner-friendly than many alternatives, as it eliminates manual charger programming mistakes. Beginners should still learn proper LiPo safety practices including storage in fire-resistant bags and never leaving batteries unattended during charging.
• How many charge cycles will this battery reliably provide? — With proper care including balanced charging, storage at safe voltage, and avoiding deep discharges below 3.0V per cell, this Gens Ace battery will provide hundreds of reliable charge cycles. The premium manufacturing and G-Tech intelligent monitoring help maintain capacity far longer than budget alternatives. Most users report excellent performance across 500+ cycles before noticeable capacity loss.
