Still working through charging discharging and testing these cells, using solar in the shipping container now so I built two 8 foot runs using two 60 amp chargers. Waste of time and money probably but it looks neat :)

Very cool. I have 480 of these cells that I need to charge, balance test and assemble. What’s the McMaster part number for those holders?

Heh about same as me. I've also 3d printed some holders and am milling busbars, they are a good value but hella lot of work


Type B
I did one rolling busbar setup but transitioning rest to 3d printing probably.

I've used straps too but not as efficient.

For the holders, I’m going to mill an array of holes out of .25” uhmwp and have the cells supported on each end. I contemplated 3d printing, but I would be printing into next year to get that all done.

I recommend capacity testing for sure, I've gotten a wide range

I considered that as well, 3d printing isn't taking too long but I'm doing a 4x4 wall mount print for 16s
 
Nice. Yes I’ve read your earlier posts and expecting that I’ll have to replace some cells that are off on IR and or capacity. Too good a deal to pass up though.

I’m going to mount the plastic racks of cells into heavy duty garage shelving units that will be turned into enclosures, also on wheels like your setup.

Look forward to seeing it! Yeah milling from a good material will beat 3d printing in most regards I am guessing.
