Hello! I'm looking into a 18650 powerwall and every example/build/etc I've seen often does all the cells in compact, soldered setups (unless it's Jehu's pcb variant).
What I imagine would be a nice big patch of wall (in the image above, the wood is a 4x8 sized ply) that would hold 13s (48v) with anywhere from 60 to about 90 parallel's worth of cells. In the diagram, those black boxes are actually modeled to be cell holders.
Yes, totally would not be an efficient use of space, but slap a piece of plexi on top and it morphs into art (imo). I also really like the idea of being able to very easily swap out cells, should ones go bad, without having to desolder, or even disconnect and disassemble the entire thing.
As seen from a more simplistic wireframe view.
If the bus bars connecting here were of sufficient copper mass, this would work, right? What I can't think of is a graceful solution tohow to fuse these. Or...would you even need to?
Alternatively, if this is egregiously stupid (given I can't find any examples of it), where's my dumb? Or maybe it has been done, and you can help me find it?
Thanks!
