What battery should I use?

[Harry76]

Hi, I am very new to this kind of stuff and have a bit of confusion when it comes to the battery.
Currently, I was planning on using a KK 2.1.5 flight controller, D2822/14 Brushless Outrunner 1450kv Motors (http://www.hobbyking.com/hobbyking/...Brushless_Outrunner_1450kv_AU_Warehouse_.html) and F-20A - Hobby King 20A 3A UBEC ESC's
(http://www.hobbyking.com/hobbyking/store/__25046__Hobby_King_20A_ESC_3A_UBEC_AU_Warehouse_.html)

All of this on a DJI flamewheel f450.
I was wondering, what battery would be compatible and be the best choice price and budget wise for this build?
http://www.hobbyking.com/hobbyking/...Flightmax_3000mAh_3S1P_20C_AU_Warehouse_.html would this work? Would I need a voltage regulator?
Sorry if I'm unclear I'm very new.

Kinda hard to tell as HK doesn't seem to provide much direct info on amp draws, just watts. Assuming the C rating is accurate you are looking at ~60Amps available or ~15A/per motor. If I calculated correctly (13.3A/per motor), it should be OK.

Although the mAh is slightly less (a tad less flight time) this battery will provide ~21A/motor.
