Plastic holders for Fortune Cells are not all the same.

[FilterGuy]

When @Will Prowse first reviewed the Fortune Cells he showed how long pieces of all-thread could be used to hold them together.
I found the fortune cells at Jiangsu Frey Battery but they do not have the holes.

Will lists two vendors on his web site for these cells. One vendor has the caps with the holes one vendor has the caps without the wholes.

I contacted Frey about this:

Do you have the version of the plastic guard that have the holes for bolting them together? (See attached picture of Plastic Guard with the Holes)​

This plastic guard is designed by our another American customer,and only could sell to him.

So.... if you need the 'bolt-together' frames, make sure the vendor has them.

Good catch!

I have the fortune cells but I built a case for them and am not using the threaded rod (which does not come with the cells unless you are @Will Prowse ?).

It would be a real let down for someone expecting that feature for sure.

I had to buy my own rods actually because the ones they came with (when I first started filming that video) had the wrong thread pitch. So I went to hardware store and found the right ones.

Now I just use my own threaded rods, deburring tool and some washers and nuts. It works well.

Or build a case like you did. Do you have a picture? That's cool

16 cells properly arranged. Now to make BMS cables since my 3/8 ring terminals arrived.

It’s a rolling case that I take outdoors to charge.

I think I can power my home office for a week (NUC computer, 2 monitors, router, cable modem, laser printer/copier) and roll it outside on the weekend to recharge.

For my application I wanted to build a semi-portable system capable of running a 1500w Inverter. Most parts are on the way so here I go. This is also a "proof of concept" thing for me and if I do a second, non-portable install down the road I could easily use the same devices powered by some...

OverKill Solar makes a nice stainless rack.

Electric Car Parts Company dot Com seems to hold the patient rights to the caps with holes. They no longer sell the rods at this time.
