Uninterruptible Power Supply:
I got this power supply at an auction. It had four 6-volt 10 amp hour batteries in it, but two of them were cracked. A new set of batteries cost to much, so I just ran two wires out of the power supply and connected them to two 12-volt 120 amp hour batteries. The power supply now has a 2.88 kilowatt hour capacity, and thus can run my computer for a long time.
My computer was running off of the power supply when I took these pics.
Um, ignore the mess of wires, this pic shows the two 120 amp hour semi-truck batteries and the connections to the power supply.
