RE:RE:RE:RE:RE:RE:RE:New pics on the websiteWhy in the name of the 9 would you EVER swap out batteries? Maybe during quarterly maintenance, but certainly not on a regular basis. I think maybe you underestimate the utilization curve on modern batteries. Also note, why batteries? It's a freaking mine, it doesn't move, there are TONS of options for static power installations. Not reason the hardware can't be charging while it works in most situations, only using batteries alone when it strays from a source of power.
NEVER screw with largely untested tech on a project with no margins for sitting around an idle mine while the maker pushes out a fix for a zero day problem. AC is cheap, common, and easy to handle.
