As you see fit.
I’m increasing battery use, moving into solar power. In no way do I expect to completely replace the grid (though do aspire to it), but do want to distance myself from reliance on outlets always working. Weather permitting (it’s that time again) I move my office outside to run off solar+batteries, am replacing all my powered tools with battery-driven, planning relocation to a house conducive to solar power, have leased an EV, and am in line for a Tesla Cybertruck.
One of the many reasons is to encourage battery technology to move forward, eventually working around limits of lithium and on to more mundane materials with better performance. This won’t happen if there isn’t a market. The aforementioned truck is promising a new battery technology in that direction.
I’m very familiar with the limits of batteries (moreso than most). Given the tradeoffs, I prefer them. Only thing stopping me from working/living wherever I want is cellular coverage (hello, Starlink) - and batteries make that possible.
I’m going to build a wood burning steam engine. I’ll put vacuum tubes in my radio. My cell phone will be smashed in a vise. I’m going into the 21st century wailing and knashing my teeth. ;-D (How am I doing?)
