Re: UPS batteries



Hi,
 
Mine has 12V batts totalling 108v DC. Which is probably capable of serious burns. Also the internal cap must be pre-charge before slapping in new batts.
 
The inverters MAPLIN sell are available at much cheaper prices from the US. I have a 300W one in my van. I think the make is cherokee.
 
Steve.

Most UPS's that I have seen use 12V batteries but run on 24VDC

ie. 2 x 12v batteries in series.

By doubling the voltage you half the current. This makes it much more
efficient.

Large commercial UPS's often run on 48V.

Also take a look at http://www.bkelec.com for low cost inverters if you want
to get mains power in your car.
