(1) We are using brickpi to drive a lego motor car. We ran scratch code to make the car move around. On the second iteration of the execution, the batteries got very hot and melted the pack holder (at the cable connection slot). Anyone experienced overheated batteries? We used 8 AA amazon basic rechargeable batteries that I charged just before using them.
(2) Has anyone tried using one 9V battery instead of 8 AA batteries (1.5v x 8 = 12V) that are typically used to power brickpi?
