FAQ

What is the Gens Ace GEA8002S45JS battery designed for? It is designed for compatible small RC helicopters, drones, park flyers and other compact electric models that require a 7.4V 2S LiPo battery with a JST-SYP power connector.

Is this a 2S or 3S LiPo battery? This is a 2S battery with two lithium polymer cells connected in series and a nominal voltage of 7.4V. It is not a 3S 11.1V battery.

What type of JST connector does this battery use? The main power connector is a JST-SYP 2-pin plug. The separate balance connector is JST-XHR. These connectors serve different purposes and are not interchangeable.

What is the difference between the power plug and balance plug? The JST-SYP power plug connects the battery to the model's electrical system. The JST-XHR balance plug allows a compatible balance charger to monitor individual cell voltages during charging.

What does the 45C discharge rating mean? The 45C rating describes the manufacturer's specified continuous discharge capability. For an 800mAh battery, this corresponds mathematically to 36A. Actual safe operation also depends on connector limits, wiring, temperature and application.

What does the 80C burst rating mean? The 80C rating refers to the manufacturer's maximum short-duration discharge specification. It corresponds mathematically to 64A for an 800mAh battery, but it should not be treated as a continuous current rating or a guarantee that the JST connector can safely carry that current.

How large is this battery? The published nominal dimensions are 52mm long, 30mm wide and 15mm high. Allow extra space for wires, connectors and manufacturing tolerances.

How much does the battery weigh? The manufacturer lists approximately 50g. Actual pack weight may vary.

Can I use this battery in an RC car or crawler? Yes, if the vehicle supports 2S LiPo voltage and the battery dimensions, JST connector, polarity and current capability are suitable. Do not assume compatibility based on voltage alone.

Can I charge this battery with a USB charger? Only if it is a dedicated charger designed for 2S LiPo batteries and supports the correct balance connection. A standard USB phone charger must not be connected directly to the battery.

Does this battery support G-Tech smart charging? No. This is a conventional Gens Ace Air Classic LiPo battery, not a G-Tech smart battery. Use a compatible conventional 2S LiPo balance charging procedure.

What charge current should I use? Follow the battery manufacturer's approved charge-rate instructions. Where a higher rate has not been confirmed, 1C corresponds to 0.8A for this 800mAh pack.
