You should be able to safely run it on a 7.4V lipo out of the box. I run mine on a 7.4V lipo right now but I used to run it on a 9.6V NiMH.

Note, I run a G&P SOPMOD but the internals are pretty much the same between different models, only the externals change (it's stupid to have different internals for different models of guns when you can have a "common" set of internals that you slap into different models with different externals because it's cheaper to only have to develop 1 or 2 sets of internals rather than 50+ for every model of gun).
