NiMH cells have high internal resistance which causes the voltage to drop under
high current loads. NiCads do not have this problem. NiMH are fine
as long as you know the cells you are using can handle the demand you are

<br>
I ran those servos regulated to 6V, the 4.8 thing has to do with unregulated
Nicads as has been mentioned. You can get a pretty high voltage on a 6V
pack.<br>
<br>
If you regulate a 2s lipo you wont have any problems with those servos.
One of the pluses of a brushless is that is should be more tolerant of higher
voltages anyways, but I have not tried higher than that. Maybe some of
Ed's new regs are in order so I can play around! :)<br>
