Technical Performance

The GENSACE G-Tech 4S 3300mAh 30C battery represents the pinnacle of lithium polymer battery engineering for mid-range RC applications. With a nominal voltage of 14.8V across four series-connected cells, each cell maintains approximately 3.7V nominal voltage with a maximum charge voltage of 4.2V per cell (16.8V pack maximum). The 30C continuous discharge rating permits a sustained current draw of 99 amps, calculated by multiplying the 3300mAh capacity by the 30C rating and converting to amps. This performance envelope makes the battery suitable for brushless motor systems in the 4000-6000KV range, though actual power delivery depends on your specific ESC current rating and motor configuration. The 60C burst rating extends to 198 amps, providing headroom for aggressive acceleration and dynamic manoeuvres without triggering low-voltage cutoffs or battery protection circuits. Gens Ace's G-Tech chemistry is specifically engineered for high-performance applications where stable voltage delivery is critical. The low internal resistance architecture ensures minimal voltage sag under sustained loading, preventing the power loss that would otherwise occur during extended high-load periods. For RC aircraft applications, this means consistent lift and handling characteristics throughout your entire flight window. For RC vehicles, it translates to responsive throttle control and predictable acceleration throughout the entire run. The battery's thermal stability allows for simultaneous discharge across multiple applications without excessive temperature rise, a critical consideration if you're operating multiple RC systems from a single battery or pushing performance limits during competitive racing or aggressive flying. The 331-gram weight strikes an optimal balance between energy storage and vehicle weight, ensuring you benefit from the full 3300mAh capacity without compromising your aircraft or vehicle's weight budget excessively.
