Default What is the right criteria to choose the #C on an Lipo battery ?

I have a 60 Ugly-stick ready to flight with a Turnigy G60 Brushless Outrunner 500 motor.
I already have available from other model a Turnigy Multirotor 5200 mAh 22,2V 6S 10C battery. My concern is about the 10C, should it be higher ? Why ?

Odds are you will pull more then 50 amps at full throttle which will work the battery too hard. I would go a minimum of 25C.

I think with a 10C battery you will feel a lack of power. The higher the C rating, the better your plane will perform (more power). The "multirotor" packs are low C rated because all the multirotor has to do is hover and a higher "C" rating isn't required in order to achieve that.

I'm no expert,, but the way I understand it,, basically a 10c 5200 mah pack is designed to give the motor a max of 52 amps at a time,, that motor I suspect will want more like 80 amps (even though HK says 65amps) when you give it full throttle,, What will happen is the esc/moror will try to draw those high amps and will cause your battery to get hot and fail prematurely in addition to not giving the motor the full power it needs,, Go with a 30c minimum to have wiggle room and not over heat your packs

many web sites out there to inform on this,,, https://fpvfrenzy.com/lipo-c-rating/

good luck

Also its important to understand that C ratings are as much marketing hype as technical spec. Many, especially cheaper packs, are shall we say, on the optimistic side.
