Frequently Asked Questions
- What RC models is the Gens Ace G-Tech 800mAh 2S LiPo suitable for? — This battery is specifically designed for 250-size RC helicopters and 800mm warbird aircraft, where its compact dimensions and lightweight construction provide optimal performance. The 7.4V output and 800mAh capacity make it ideal for small-scale electrically-powered RC models where space is at a premium and weight matters significantly.
- What does the 45C discharge rate mean for performance? — The 45C rating indicates that this battery can safely deliver 45 times its capacity in amps continuously. For an 800mAh battery, this equates to approximately 36 amps of continuous discharge current, providing the explosive power needed for aggressive flying, rapid acceleration, and responsive control input handling in your RC aircraft.
- Is this battery suitable for beginners? — Whilst LiPo batteries require proper charging equipment and handling knowledge, the Gens Ace G-Tech is an excellent choice for intermediate and advanced RC pilots. Beginners should ensure they have an appropriate LiPo charger, understand LiPo safety protocols including proper storage and balancing, and use a charger with integrated safety features. Once you're comfortable with LiPo operation, this battery offers superior performance compared to NiMH alternatives.
- What connector type does this battery use? — This battery features a BEC (Battery Elimination Circuit) connector with JST standard specifications, ensuring direct compatibility with virtually all standard RC receivers and servo systems. The BEC connector eliminates the need for a separate power distribution block or voltage regulator, simplifying your electrical setup.
