You could always bring on crew aboard Chris' comments seem to be dead on. With your 22Ah jumpstart, and 4hr/day x 5 days x 1.5A (assuming the worst) = 30A. Now, with the 1/2 factor that Chris talks about, that's about 11Ah usable before the battery starts damaging itself if it behaves like deep cycle marine batteries. So, you'll probably need 3 jumpstarts dedicated to just scrape by on Ray's requirements. Considering the costs (2 more jumpstarts and/or optional solar), you may want to consider adding one marine battery from Sam's or Costco. And just do wiring directly to Ray (with a fuse!). The weight of the marine battery versus 2 additional jumpstarts would probably even out. |
No Amp-Hour rating involved! However, they do have some limitations. 1) They require food 2) They require water 3) They can be heavier than a battery But, their food and water consumption translates it into stored energy, but is not entirely waste-free. And, you can try to make them swab the deck if they spill a can of soda on the shiny gelcoat.
