I've added a 'balance lead' to one of my eBay Chinese 12v battery packs, this allows me to connect a display which reads the voltage from each of the three cells or to warn me when the cells voltage get too low.

The warning is a loud bleep with flashing red LEDs, perhaps this can be changed to a vibrate motor instead so to not scare off all the bunnies.
