I'll probably be the only one to admit using knock off batteries, I can't really tell the difference, but they do make me a bit nervous.. Mainly because of all the negative stuff I've read online. Honestly, when it comes to a battery I'd probably go with DJI. But for me, I was looking to have a ton of batteries, so the price difference was a big deal.
As far as performance, the only thing I've noticed is the fact that the knockoffs don't auto discharge like the original ones.
Other than that, I get the same flight times and charge times as DJI batteries.
