Just enquiringly on how to do the upgrade that it's telling me is needed for the battery? Thank you!

Basically, Check in the Go app, to see which firmware versions you have already.
Then download the latest version bin file, with battery support onto your sd card.
Place it back into the drone gimbal and turn on the Phantom, by itself.
Takes only minutes to upgrade a flight battery.

You also have to do this with each battery.

Very simple process

Thanks but it seemed to off just sorted itself out one battery was fine and the other said requires upgrade so when I come back to do it all it said was leave it level to sort it out and if it persist contact dji but it seems fine now

Was asking because my brother got the same one and it just fell straight out off the sky with no warning and it smashed to bits and he read up there was an issue with the battery causing them to drop out the sky I didn't want that happening to me! What would be his options from that situation he's not happy which I wouldn't be to happy about either considering the price of these things
