Brushless Revo + A123 and ICE

Yup, it is 3.6v. At first, I wasn't sure I liked it, but it's pretty nice. I emailed the designer and we had a little chat about how it worked and I like the algorithm it uses.

To figure out what size PS you need, you can use this page as a guide. The table below is for the Xtrema:

Input V   Min A    Safe A 
 11.0V    20.5A    25.6A   
 11.5V    19.6A    24.5A   
 12.0V    18.8A    23.4A   
 12.5V    18.0A    22.5A   
 13.0V    17.3A    21.6A   
 13.5V    16.7A    20.8A   
 14.0V    16.1A    20.1A   
 14.5V    15.5A    19.4A   
 15.0V    15.0A    18.8A

It's obvious that a higher input voltage will require lower current so try to find a PS with a solid voltage. Most dip down once you start drawing some heavy current...
