The Sony Flight Battery for Airpeak S1 Drone is an add-on accessory for the Sony Airpeak S1 Professional Drone & Gremsy Gimbal T3 Kit. If you need an extra battery with your rental, you’ve come to the right place. This 2518mAh battery provides up to 22 minutes of flight time without a payload, so expect reduced times when flying with a gimbal and camera attached. Please note, if the batteries have more than a 20% charge difference, the drone motors will not engage. This rental does not include a charger, but we do have the charger available as a separate rental product.
