I use the above airhead pump also with a Li drill battery. Use any 12v drill battery that can be adapted with slip on/off spade connectors. This pump is rated for 2.5# pressure though I have not been able to get that much pressure. I like it for boston valves because I don't need to top off the ODC 420 or use a pressure guage, it gets me to the right pressure every time. That's a great price, I paid $50.
