Well, I did not measure the voltage under such high current but I recommend to perform a practical test on your side. The components are cheap (the 2 moduls an da single cell) should not cost more than 12-15Euro/$.
I searched for the maximum current of a servo and found only a 13kg servo with 1.4A at 13kg maximum at 6V. So I think a 17kg or 20kg servo will stay below 2.5A. However here is a 4A module:

Regarding the NiMH cells... ok if the praxis shows it is working, it´s fine but theoretically you will stress the 2 cell packets since they always have different capacity when starting to recharge them.
