think i get it .. was looking at the article in projects and looking at all these 2500 mah rechargables i have managed to accumulate
useing your example dr m
and bumping up the draw 10 times
( i think this is closer to what they would be actually useing )???
a 12 v supply of these batteries would barely run for 2 hours ???
thanks all .. thought it didn't seem possible somehow
but didn't hurt to ask
