I have a serpent box that used to be run off 2 stick packs but the previous owner just cut about 6 ft. of cord off a bad car battery charger (with the two big alligator clips) and soldered them directly to the motors on the box and I just drive around with a spare car battery in the back of my bronco and every weekend I use it to power my starter box and my battery charger for all my batteries (tx,rx,glow ignitor, etc.) and it works beautifully. Another plus is that if I ever get stuck with a dead battery I have a spare in the back! As far as amperage goes, this battery has 650 cold cranking amps and my starter box works great with it. I have even seen guys using those jumper boxes, for jump starting dead car batteries for their boxes but they dont last as long as a regular battery but they can just be recharged by plugging them into a 110 outlet.
