Actually... no.. I have nothing concrete to base that they are good, bad or indifferent.
I see some say they don't have any problems with 3rd party compatible batteries. Others say they their bird wont even recognize them
I personally just cancelled an order on 2 batteries that I thought were OEM .. they we're priced like OEM but on "SALE" .. It was like getting 2 for 1 ..
A tip from your old pal Bob ... There is no such thing as a free lunch, if it looks to good to be true .. it is .. and OEM Phantom batteries are 150 bucks .. ( unless you can find the one in 100 Game Stop stores that has one in stock for $50 ... in store only .. not online)
I always flew gas in my planes and heli's ... if they ran out of gas or the engine quit.. I could dead stick or auto-rotate back home ..
Your drone quits at 400' from a battery failure ...its a painful sight to watch $500+ fall and self destruct.(Praying it doesn't hit something or somebody)
Something to think about ..
Bob
