Arri 2c motor/battery

[Phillip Mosness]

I've recently acquired a 2c with a constant speed, and a variable speed motor, and now my question is the best way to power them.

I was told 16 volts is the appropriate type for this camera.

One of my Aaton batteries happens to be running 15.6 volts and seems to power the constant speed motor fine, but for high speed stuff, would a 24 volt motor be a problem?

12/24v batteries seem way more common.

Thanks.
