i actually had an idea of perhaps not going with lead acid batteries.. but using some of the lighter sealed batteries in a backpack with a cable coming out and going into an old battery pack thats been cleaned out to be used for a plug to the power tool.. if i was doing work all day, these batteries with 150-200ah would last all day, sure... id look like a ghostbuster, but im sure that wouldnt be any more fatiguing having larger batteries on my back than it is to have a smaller one on the end of my arm (leverage and all that)
im looking at one of the low profile battery packs now, i could easily reuse the locking mechanism and rail to slide into the base of the power tool, drill a hole in the base of the battery, mount a rubber boot in there to protect the power cable and have a large gauge power cable coming out of it
as for the possibility of a power supply... these power tools are 18v at a maximum of what? 20 amps?... under 400 watts of power... a PC power supply puts out this and much higher wattage on 12v which means it needs to run at higher amps... so i was thinking of gutting the chassy for a PC power supply and building inside this an 18v 20-30 amp power supply... and looking at the size of PC power supplies and the size of the XC batteries from milwaukee, i could probably put the guts of the power supply into the shell of the larger battery... 110v @ 5 amps in, 18v at 20 amps out
so these ideas are quite plausible... in fact, with the battery pack on your back, you wouldnt even need to go that extreme, a 20ah pack on your belt would be absolutely enormous and last all day... and i think these power drill manufacturers should be considering belt and back mounted options
