Anyone know if the 1268 can handle 2s lipo/8.4v direct?

I did have mine running through a CC BEC powered directly at 7.4v but today I roasted the BEC and thinking about running the servo directly from my 6s lipo (Mugen MBX5T-E).

I have put together a plug and a Y adaptor servo lead that plugs onto the balance plug on the lipo to get the 2s voltage.

I was thinking that the extra drain on 2 cells would be negligible, not 100% sure but I think would be worth checking out and I wouldnt have to worry about burning out another CC BEC (or is there another/better BEC that can handle 6s input and 7.4v output?).
