Why not start with a battery powered mower in the first place? I have a B+D that I've used for three years now, works great. 38AH 12V battery, plus motor, and control relay. Their charger failed two years ago, so I just brought out a direct connection via PowerPole, and I charge it with an external. (Silly, imho, to put the charger electronics in there, at least in a walk-behind version) -- Dave's Engineering Page: http://www.dvanhorn.org Where's dave? http://www.findu.com/cgi-bin/find.cgi?kc6ete-9 -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
