Robot - High amp draw and battery(s) question.

I'm currently working on a humanoid robot project and i'm up to 16 servo's in the legs now. The servo's amp draw is listed as:

Voltage 7.2V 8.4V
Stall current (at lock) 3.2A 3.5A
Idle current (at stopped) 4mA 5mA

The total amount of servo's will be somewhere around 26-30. The battery i'm currently using is a LiPo rated at 7.4V 25C 7000mAh. The awg of the wire is 12 which is rated for what people say 20-40A+.

My question is, to lessen the stress of the battery at higher draw currents later on, can I do something like, wire 2 of these battery's in series(oops, meant parallel) so they share the load and cut the power they each need to supply in half?

Not series. That would double the voltage.
Parallel. That doubles the capacity making it a 14000mAh pack at 7.4V.
30 servos at 3.5A is 105A. That works out to 7.5C, well within the 25C rating.
You would get about 8 minutes of run time if all the servos are operated at stall current, but I suspect that will not be the case.

Oops, thanks for pointing that out. Haven't had my morning caffeine yet heh.

I'm expecting about 25-50% power draw if I get it moving so hopefully I can get around 15-25 minutes of operation time.
