I'm looking into the idea of using two parallel 5s lipo packs to power a 14,4V Dewalt motor. This all on a stock EVX2.
We are discussing it here:

A couple of questions arised in this dicussion which deserve a new thread I believe.
- Would be possible to use an external BEC with the EVX2. Can anyone answer this?
- Also, would this take the load off of the internal BEC in the EVX2?
- And If the internal BEC were to be destroyed, would the EVX2 still work with an external BEC?
- Does anyone know if the internal BEC is a switching or a liniar regulator?
