The R8B draws a lot of current...2 amps. So, he's going to need a
serious battery. For 20 hours of usage between charges, he'll need a
40A/H battery if he's to avoid 'deep discharge'. That's going to be
heavy, and expensive.

At that current level it isn't really practical.
Like you said a 40A gell cell is going to be HEAVY.
Unless he is at home, or in a camper he needs to get a
portable SW that will use less power.
