Re: UPS
"A car battery - which is what a UPS is, tied to an inverter - is 12v 400A or more. I guarantee you that you don't want that discharging through you in any way."
No. A car battery is 12V & 400AH. Amp-Hours is the unit. That means it is theoretically rated to supply 400amps for 1 hour or 200 for 2 hours etc.
400Ah is a honking big car battery; most are 40 to 70Ah for family cars, and up to 100Ah for the average van. I read it as 400A current capability, or in car battery parlance, Cold Cranking Amps, the current it can deliver to your start motor on a frosty morning with your engine's content resembling molasses.
