I assume you are going to use the proper
voltage regulator and plugs. $35,00 to
$65.00)
I would us a marine battery ($75.00) it
well last longer then a regular car battery
($45.00). I use mine all day on a trolling
motor on my boat so I would think it would
run for a few days, but to figure it out
exactly you need to do some math, Amount of
amps and volts needed to run unit and the
amount of amps and volts in the battery. I
would think by the time you buy all this it
would be cheaper to just run and out door
outlet. !00’ or less of in the ground cable
is not that high in price and a out door
outlet all should not be more then $75.00.
Not that hard to wire into the house or
another outlet near by.
