Errr, sorry..

That was 650 VA - and it was like a one time offer from Bestel,, I bot last year at Ksh. 3500 - someone must have made an error [the guys at the counter :) ] , because I went back this year and suggested prices were as quoted by Alvin.

However, can someone link up several 1 hour UPS in series or parallel for them to last longer hours ? Anyone tried ?

The car battery connection in parallel with a UPS battery from Lawrence, is one example I am hearing...
