12 amp hour XRP 18v battery


Recommended Posts

Three ub6120 batteries(40$)on ebay can be wired to an old dead 18v xrp battery with a cord to make a 12AH sla battery superpack.  I've been cutting 2" galvanized drain pipe with it no problems.  To make room for the cord in the battery I just removed three cells, drilled a hole in it. pushed a tool cord with a knot on the end through.  wired it up black to black white to white wire.  I left the center post grounded to black so superpack will recharge with oem charger.  easy money, all day.  I think this pack would be great for those xrp tools that eat juice like grinders, cut offs, hammer drills and sawzalls. But i'm only running the saw.  I had a spare saw i'm running it on exclusively.  So far I love it.  Wish I had the tire gun...Dewalt should make some sort of work stand with a bigger 18v backup battery to run a radio or various tools for whatever if power is out or a cord is not an option IE 44th floor of an unfinished building.  I woulda bought that.
