LiFe, BEC replacement

[zeropointbug]

I just went and bought a 850mah Hyperion G3 LiFe rx pack for $16 to replace my BEC (Pro BEC). I am going to use a rx pack because I don't trust the BEC anymore, at least for racing. I think these little things are great alternatives to a BEC for a couple reasons I can think of:
-it will always work (as long as it's charged), can never fail, no power interruptions
-higher voltage than a BEC, faster, more powerful servo operation

It doesn't weight that much either, just under 50g... so it wouldn't even be noticeable over a BEC equipped truck. It may even extend radio range because of less electrical noise in the system? BrianG?

I know Brian might be interested in one of these, no?
