I'm planning on maybe taking it on a raft trip if I pull a weekend thing.
Maybe my smaller (and louder) one.
I'll run it & a battery charger while running the raft upstream, possibly with something rigged up to route the exhaust underwater. Then when we get to the camping spot, I'll set it next to the water if I have an underwater exhaust system, or just put it 100 feet out into the woods & use an extension cord for the charger, just til the deep cycle batteries are topped off then kill it for the night.
It's hard on lead acid batteries to leave them sitting in a state of discharge for very long, and I predict that running a heavy loaded raft upstream for 7 miles with a 40# trolling motor will use up about 50% of its capacity even with a 10-15 amp charger on them.
The deep cycles will run the stereo and LED lights all weekend with no problem.
It would make more sense to just use a little outboard motor, but that would require buying one. I already own the other stuff.
