Hmm. I've never considered using a non-DJI battery on my own drone. Something about the possibility of a failing battery on a device flying high up in the air really scares the crap out of me. The real test is not really whether or not the battery works (I'm sure it does), but how long it will last with repeated charges and flights under its belt. The DJI batteries hold up really well. I wonder if this Powerextra 2-pack is just as good for $115 (a normal DJI battery costs $89).
