What is the FULLSEND 3S 450mAh 75C LiPo Battery?

It is a compact rechargeable lithium-polymer battery designed for compatible FPV micro drones, 3S whoop quadcopters, and small H-frame aircraft. It provides 450mAh capacity, 11.1V nominal voltage, and a 75C discharge rating.

What is the nominal voltage of this FULLSEND battery?

The battery has a nominal voltage of 11.1V. A fully charged standard 3S LiPo battery reaches 12.6V.

3S1P means three battery cells are connected in series in a single parallel group, providing an 11.1V nominal battery configuration.

What connectors does the FULLSEND 450mAh battery use?

It uses an XT30 connector for the main power connection and a JST-XHR-4P balance connector for compatible balance charging.

What does the 75C discharge rating mean?

The 75C rating indicates the stated discharge rate relative to battery capacity. Multiplying 450mAh by 75C gives a theoretical current of 33.75A, but this calculation alone does not guarantee a safe continuous current in every setup.

Which drones are compatible with this battery?

It is designed for compatible 3S FPV micro drones, whoop quads, and small H-frame quadcopters. Verify the required voltage, connector, battery dimensions, and current needs of your specific drone.

Which charger should I use for this FULLSEND LiPo battery?
