He is a nifty little circuit that will allow you charge stuff from your scooter's battery (the scooter's motor is not running) while simultaneously insuring that there will be enough power left in the battery to start your scooter if you leave it unattended for too long.

With a little work you could add a timer to this circuit which would cut off the power after a fixed time period or if the power gets too low. I could also see this being used a method to activate a trickle charger. When the relay trips because the battery voltage is too low a circuit to a the charger would be activated.

$15 bucks for the kit, but requires a moderate level of electronic's experience.
