Price this battery in charges. It takes two pieces of tech trash, exactly what one C4 asks for, and no bench in the game makes more. So the day your group crafts a large battery, it raids with one charge fewer. The high quality metal is the easy line, a small share of one furnace run.
That trade is worth making for the battery that carries your night defences, not for every room. One large battery behind a few solar panels keeps the turrets awake until morning; a second pays only when the first runs flat before dawn. Bench, research and craft time all match the medium battery, so the only thing you save by stopping one rung lower is tech trash.
Watch out
Don't recycle a spare. The ordinary recycler gives back one of the two boards, and no bench of yours replaces the other.
