that's why battery holds in a car is metal, so you have
to buy a new car every few years :-)

i assume that's 2 batteries in parallel and those 2 pairs in series
	- do you use electronics to adjust for 14.0v vs 14.5v

	even a 0.1v difference between the batteries at 500A 
	will be a big heat generator ( too hot to touch )

- nice big fat 1awg stranded cables ??

-------

for mini-itx systems that uses 3A per p4-3G+mb+mem+disk
that'd be enough power for 200+ of them mini-itx boxes
as long as the batteries can be kept charged

and 2A additional (5A total) peak power during the first 
2-3 seconds of power up at 12vdc
