Hi friends.. I am beginner with little knowledge of electronics...
I have a turnigy g10 1100kv motor with 40A esc .. can someone please suggest a lipo battery for this I am  confused as to what does 20c, 30c, 40c mean.. Secondly.. I have airtronics rx600 receiver.. I dont know what NiMh or other battery pack should I use to power it.. someone suggested not to use Lipo pack with this one... I link pointing where can I buy these packs economically will be of great help... thanks

20C, 30C describe current supplying capability of lipo.
Eg:
If you have 20C Lipo rated at 1000mAh current rating, it means It can provide 20 x 1000=20000 mA or 20A of current.
While your motor needs 32 A current I would recommend 2200mAh Lipo rated at 20c-30c..
