Re: Back-up battery charging circuit from IFI
One recommendation I would make after seeing the schematic is to mount the LM317T (regulator) to a heat sink or piece of copper. This is the unit handling the power dissipation and it may get too hot.

And of course you could blow something by pushing your bot. Voltage is voltage, and current is current (i wont say resistance is resistance because negative resistance gets tricky) But, the motors would have to spin faster than they do with the power on.
