A related question for rolling your own UPS, I have two 12V sealed lead acid batteries that I recently replaced ($200) in my mother-in-laws scooter which she is no longer able to use. The battery unit for the scooter is removable and is 24V (the two batteries in series) with a trickle charger, the output lugs are accessible. I can easily get a 12V full wave inverter and put the batteries in parallel, but then I lose the nice case and charger. Does anyone know of a 24V full wave inverter that might work DIY, or maybe I should just pull the batteries and go with the easy to get 12V charger and inverter.
