Arrrrr help me please... I want to convert AV (240v) powered fairy lighst to battery power?
I am trying to convert some fairy lights to run on batteries. the string of lights after the adaptor run on 24VAC 250mA 6VA... as I expected when I combined 9V batteries to produce 27V/ the batteries ran the light well (brighter that off the mains) and also as expected after about 1.5 hours went out.
Now I was wondering if there is some way to wire batteries to run these lights? size needs to be kept to a minium as does cost..
Now I know that If I was to use LED lights this would be simple. but that is not possibe as I have already got the 50 strings of fairy lights :( any help would be great...
