Sell both tanks, get a latch box-style tub such as a Sterilite 34 quart, and live happily ever after.
Or, considering that ball pythons are like potato chips and you don't stop at one, sell both tanks, build or buy a rack, and live happily ever after.
Either way you go, get a good thermostat to regulate your heat source(s).
Don't waste your money on lights, ball pythons live underground during the day and come out at night to hunt. They like the dark.
