I haven't tried the ofeely but the last 2 batteries I have bought have been the lime fuel 6000 mah. I have been very pleased so far with it and I wish my 2 other batteries were limefuel as well. Depending on conditions I usually get about 5-7 more mins of flying time and they take the same amount of time to charge as my dji batteries and they're about $20.00 less. For me they will be the only batteries I ever buy . At least for now until something bigger comes out. Awesome battery!!
I have one of those LCD ones, but mine is 5400mah.
It works great. The only real thing I could say, is it does not fully charge if you parallel charge it with other batteries.
You have to charge it by its own.
