The missing ingredient is the capacity of the pack. If it is only 2 or 300mAh you have a problem. If it is 2000mAh and above you will be fine.

I always recommend purchasing a pack by its weight to get the CoG correct within the realms of having enough capacity to last a couple of flights.

I am running two battery packs on my 700. They feed into a fail safe switch which draws power from both packs. If one drops out, the machine keeps flying. The packs are 5000ma and 1900ma, 7.2v lipos. Yes a little heavy but you can fly all day.

Hopefully you have HV servos or a regulator for the 2S LiPo

A 40C receiver pack is way overkill and expensive.

If you have a 2000 mah battery, that is a 2 amp-hour battery. At 40C, that 2 amp-hour battery can deliver 40 x 2 or 80 amps of current on a continuous basis till empty.

A relatively inexpensive 2S, 10 or 12C, battery is more than adequate for a receiver pack.
