Thanks. Your points are valid and the waterproof thing is one thing is on my mind. The Gator cases are only water resistant and intended for music bands, etc. Maybe there are some military surplus rack mount solutions. Fleabay has some but nothing with the shorter depth, just big two to three marine luggable sizes and I’m too old for that stuff. I use ammo cans a lot on the white water raft and they work well for many applications but rack mounting makes things a lot easier. Perhaps some rack mount rails can be fabricated into a can. The LiPo or LiFePo batteries are for semi-portable fields operations. For mobile it’s an AGM lead acid battery with short leadsto the amps. There is a good simple RV solution for charging remote batteries, just can’t think of the name right now. A little Honda generator is on the list for field ops. The older 500W generators should be big enough and they can be found for a couple of Ben Franklin’s but, I’m holding out for a good deal on the plastic 1 kW model. By the way Lithium Iron Polymer batteries are a great technology. They are about half the weight of lead acid and the discharge curve is very flat. They are also safer than LiPo but most LiPo issues are user induced and they aren’t nearly as unstable as the media wants you to believe. I run an electric fishing kayak on a 60A/Hr LiFe Po and it runs circles around the AGM lead acid that I keep on hand for a back up. This particular LiFePo will also pull a 100 amps without issues other than a faster discharge rate. LiFePo is a seriously great technology and it will will be interesting to see what’s coming up next. That doesn’t mean that I’ll be buying a Prius or Tesla anytime soon. I’ve love my V8s and we aren’t talking GMO tomato juice here.
