After a fun weekend with the back-up batteries, we were told about the back-up battery charger on the ifi website that charges the back-up battery from the robot's main battery.
Has anybody made this circuit and if so, what are your thoughts, suggestions, etc. We want to make one in the fix-it-window before the Detroit Regional, but any lessons learned, advice, or whatever is appreciated.
Thanks.
