Hi Alex,
I actually use a 12V 10000 mAh LiFePO4 for Pi Robot since it is significantly lighter than lead acid. In the blog post you reference Pi's total weight was 17.4 lbs (7.9 kg) and the motors had no trouble moving the robot across flat surfaces such as low ply carpet. The main reason I wanted to lighten the robot a little with the LiFePO4 battery was to make the robot easier to carry to and from my car.

Dear Patrick,--
I am now building a differential drive robot using the Pololu 37D 12Vgear motors (100:1 gear ratio). I see that you have also used the same motors for the pirobot build (http://www.pirobot.org/blog/0024/).
I am wondering about the kind of battery you are using to power all the components. I plan to use a lead acid battery (12 V). As you are already using this setup can you tell me whether the weight of the batteryhas any effect on the performance of the robot motion and motors (heating up etc.) in your version of pirobot.
Thanks
Alex
