Title: Powering standard servo with Ni-cd 12v 1600mA?
Post by: BANE on January 25, 2008, 08:00:50 PM

Can I use a voltage regulator to knock the voltage down to 6v and still get the 1600mA?

yeah. but the regulator wont be happy supplying servos with electricity. get a switching regulator. much more efficient and wont burn up

Ok, so theres no way around it, all buy a 6v 1600mAh.  I have another question, theres a voltage rating for servos, but what about mAh?  I know what VDC does already.  I've seen 600mAh, 1200mAh, and 2800mAh, (elementery question) how does mAh effect the servos performance?

Oh that makes sense :D (never knew that).  Heres a question, if get 12v 1600mAh battery and reduce the voltage to 6v, would i still get 1600mAh?
