We have tested it to work reliably for over 50 drops per charge.It also has a standby time if left on of over 2 weeks, however we recommend keeping the device fully charged at all times.Please do not try push its limits as battery life can change which can cause a failed drop, meaning you will have to fly back all the way with your bait still hanging from the drone.For this reason also don’t push the limits of your drone’s battery, always ensure you have sufficient power left for a full return trip as if the bait is still attached to the drone remembering that you might have to fly back against the wind.
