Operating Voltage: 4.8V to 7.4V

All servos are designed to run from a 2S LiPo.

Sorry about that, here you go. Updated product info: Continuous Rotation HDD Servo

@DJ.... Wow! at 7.4v that's over 100 oz/in.... That's twice Hitec's CR specs.... Kudos.... I know where my next servo order is coming from....

:) Thanks! We have our servos specially built for EZ-Robot Revolution. They are not servos available anywhere else. We had to design the requirements ourselves because there were no others with matching specifications.

Correct me if I am wrong but based on the max voltage of 7.4 the expectation for powering the servos directly from the EZB and battery holder in the developers kit is a no go without some voltage regulation involved.

It takes 6 batteries at 1.5 volts = 9 volt.

Using rechargeable batteries I am measuring around 8 volt from the power pin of the digital ports of the EZB.

Thanks

The instructions included in the developer kit states to use rechargeable batteries

I can't remember the thread but there was a discussion on staying away from alkaline batteries with the developers kit. A couple reasons being that it's expensive to use servos with alkalines as they chew through them and they can't provide the current required by servos sometimes.

Yeah, the Max voltage rating on servos isn't the absolute max it's just the max recommended voltage, you can go higher. We test our servos at the LiPo Max voltage of 8.4V because that's what 7.4V LiPos put out when they are fully charged so 8V is ok. It is likely the rechargeable AA batteries you have will drop under load anyway, so you'll be good.

@Jeremie

Thanks for that clarification.

@DJ

So just to clarify:

1. I am using rechargeable batteries
2. Perhaps I am missing something DJ but there was no instructions in the box. I saw the use of rechargeable batteries on the website learn section.

Finally:

I am giving this to rich since he gave the answer to my main question first.

Thanks
