4S Life suggestions

[DaveG28]

Am tempted to try out a couple of the new Reedy Life packs for various classes including this, they are 4000mah 30C I think. 2x2S would give 13.2V voltage, between 3s and 4s Lipo.

So would there be a way of getting a decent package out of this to last a 10 min run? I can get 15mins out of 5000mah 4s lipo, so not sure the Life would do 10?

Also, what sort of kv motor would I need to be quick enough with that?

Finally, as receiver packs annoy me, which esc's would run his voltage ok and provide power to receiver/servo's etc as well? Or would I need a receiver pack?
