Default LIPO "C" rating for Align 3550KV motor

I've got a beaten up 11.1v 2200ma 18C battery that came with my nice 2nd hand Trex 450se. It has a Align 430L 3550KV motor (the new model of motor) + 35AMP align ESC. Want to buy a good lipo for it. Can buy a 15C constant off ebay locally kind of cheap (EMAX branded) or can get a self branded lipo from a align distributor locally that can do 20C constant for about $20 more AUD. Bpth are 11.1v 2200ma.

What would be the recommended lowest Constant C rating to get for this motor? Would 15C be the absolute minimum. Also how does two different C values affect flight performance. I guess the higher the C value for constant the more happier the Trex would be to maintain high end head speed but then battery would probably drain faster.

15C is the minimum. Yes the higher the C or discharge rating the happier the battery will be. A 15C battery is pushed to it's limits in the T-Rex. My 15C Thunder Power pack is extremely hot after a flight. I do fly it hard though.

Get the best battery you can afford. Personally with li-po batteries I would stay away from off brands. These can be very volitile batteries and quality means a lot when it comes to safety and performance. I use only Thunder Power li-po's. They are consistently high quality packs.
