No Air Shipping

Please note that shipping regulations have recently changed for batteries. We are no longer able to ship lithium polymer batteries via any Air shipping method. This includes all international destinations outside the USA. In the USA, you will only be presented with ground-based shipping options if your order contains a lipo battery. If you need to receive your order quickly and would like to ship with one-day or two-day shipping options, consider splitting your order into an order of only batteries (shipping ground) and everything else.

Due to IATA shipping regulations, batteries shipping AIR must have a charge of less than 30%. A lithium polymer battery that stays in this state for long periods of time will become damaged. For this reason, GetFPV does not ship batteries using Air shipping.

If you want to ship batteries via air shipping, you can set up an account through our freight forwarding partner Follow the instructions on their website to learn more.
