@FWC.
Fair enough. I made some assumptions. Mostly because I figured what you were saying had at least “some” remote relevance to life ON earth which could somehow be at least loosely related to batteries in a camper….
So, sounds like a cool job, yet wholly unrelated to average or even extreme camper use.
Your replies are akin to the many other overtly literal responses and interpretations that somehow plague any sense of practical reason or application, on this forum…..
And exactly to my previous point, that just because it “can” be done, doesn’t mean it’s the right solution for the application.
