I was wondering how 2 5lb bottles work at once. What kind of set up is needed cause my cousin has 2 5lb bottles and wants to toss them in his trunk. I told him to get a 10lb but for some reason he wants to keep these. So im here to ask how to make them fully functional. Will they make the same pressure also? Can 1 bottle warmer be wrapped around both?
thanks

 

2 automatic bottle heaters would be good, so they would heat them to a psi and then turn off. this should keep the psi fairly close, all you need it a T or Y fitting and connect all the sides of them together and it will work

 

heres my setup
