2S2P of what brand & size LiPoly batteries? That makes a BIG difference.

A 2S2P pack of Etec 1200 cells will give you 7.2V and the capacity to draw up to 14 Amps. Just because the pack can produce 14 Amps continuously does not mean that you will get 14 Amps through the motor. Amps depends on how many Volts your pack has, and the configuration of the motor. The E-starter with stock motor and 10x8 prop will draw about 7 Amps.

I regularly fly my E-starter with a 2S1P pack of Etec 1200's, for about 10-12 minutes at a time. The pack gets a little warm, but not terribly so.
