So rotor windings of leg servo just burned.
But until now all other servos are ok without any regulator.


OK Thankyou.

I am thinking to switch to LiPo battery pack of 3 X 3.7 volt with 2000mAh.
I may need regulator...
I want more life from battery charge, but I don't want to short out servos of course :D

So you are able to record and save movements for later????
That would be excellent training and for achieving better walking movements!

A 3 cell lipo 11.1v will be save to use without voltage regulator if you have the RCB3-HV.
No need for a voltage regulator.
The controller and servos can take more than 12v no problem.
The voltage will drop anyway to 11.1v when under load.


I have KHR-3 which has a bit more toughness for carrying extra weight.
I am interested n the battery upgrade described earlier.
I did find a power regulator and indicator to give a bit more sophistication to power management for the LiPo's...
What do you think?
Links...
Setting output to about 11v
http://www.dimensionengineering.com/SWADJHV.htm

But only supports 7.4 volts which is not enough for KHR-3... I don't think anyways...

My LiPo(11.1V) puts out about 12.46v when fully charged. Is that ok for my KHR-2HV?

At least my KHR-1HV can handle it no problem. Just make sure not to run your robot for too long to prevent servo overheat.

Would this Li-Po fit into the MANOI AT01 body?
Is there any suitable battery available for it (possibly without $1000 worth of sensors and equipment in a kit with it)?



EDIT: Oh i see now, they also sell it alone.
