Wooden cell holder
#1
I'm considering making cell holders out of wood. I know that wood and fire sources aren't a great mix but even plastic burns, it's a great insulator and easy to work with. Am I considering doing something stupid? Any feedback?

That wood work ;-)
But like everyone says: much easier to buy pre-made plastic holders.
Unless you have a CNC like a Shapeoko, in which case you could fairly quickly cut custom wooden brackets.
I do something similar, but with plastic and a 3D printer.

@Average Joe's father did a youtube I saw once - where he used vertical PVC (sitting on a parallizing busbar) to hold cells in series.   Something like this:
DIY E-TUBE without solder or BMS 18650 Battery pack pvc pipe conduit fittings  -  https://youtu.be/AC1kmmegr78
only many vertical tubes next to each other sitting on a busbar on the bottom and clamped in place by another busbar on top. The difficulty is getting good neg-pos contact thru the vertical stack of cells - but then there are things that could be done to facilitate that.

Me - I find soldering easy/efficient and I can unsolder/resolder easily to re-arrange/re-use/fix things   Smile

I think he mentions in one of his later videos that the time and effort that went into building that was totally not worth it  Big Grin

I believe you are right.Smile
But if you had the pipe on hand and were short on funds and long on time and needed something to do why not?Big Grin

I found that PVC battery by the guy I think is Average Joe's Dad.   He did a few to cover the whole project but here's a key one:

"Adding 18650 batteries to specially built frame" -  https://youtu.be/JpHYxKGg_rk

At the the time I thought it was pretty cool (and still do) but now (that I know more) I don't see how BMS balance leads would be wired in very easily Smile

There’s to much plastic in this world. Go the wood!
Maybe pallet timber with holes drilled into it (big for batt and small for fuse to come out of)
