In order to save someone grief in watching their drone fall from the sky I'd like to emphasize caution and that you conduct full power ground tests or implement a "flight probation" period before general use. I recently bought a dual charger and two 15.2V H+/ 520 batteries from Gifi. I was more than pleased with the charger, but unfortunately one of the batteries seemed to have developed a short when flying. It didn't show any issues at first, but during its last flight on "sport mode" I suspect the battery heated up and shorted the connections. From the flight log (see red arrows on Telemetry lines below), the battery went from 16 volts to 5 volts for about 10 seconds. Just enough time to crash hard on an nice piece of parking lot. It was a spectacular show where the C23 camera took the brunt and disintegrated in front of me. When I ran to the pile of drone that was once my Typhoon H +, it was sitting there on it's side all happy and running at full power, ready to fly again if the bottom wasn't crushed. I do recall some flights before this event (used the battery about 2 to 3 times), the drone was sometimes jerky. This should have triggered warning bells in my head but I chalked it up to some minor glitch in transmission or something.
