I'd try something a little different, use 3x 6v gell batteries, I think 18v is about right, then 2 simple smps buck regulators to give 12v and 5v at the decent amps. Maybe you could run 12v battery and no/minimal 12v regulation? It could be a good system if you can charge the thing from a car battery or truck (24v) battery, or even solar. But what about the monitor? -Roman -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
