I've been using Turnigy's for a long time now, absolutely no complaints!
Totally comparable to all others I have owned except price!
The only batteries I avoid so far are overlander, every single one has swollen or "popped" after very little use.
as far as I'm concerned turnigys have proved to be the most reliable.
Just make sure to do the math, you need to be sure the battery can provide the amps required by the esc for long enough.
