Just a little :D

McMaster-Carr is who I have linked for the bus bars.

When you include taxes, shipping and hardware it's never that cheap. As this will be specific for me I am getting shipping quotes for all parts and totaling everything that comes out of the Lynx Power In. I then use this number as the total cost of the entire battery system. Then divide that...

Its setup as 33P16S. Doing it this way means I only need 1 BMS rather than 33 for something like 16S33P. If an individual battery fails, the pack will continue to function. With glow fuses, I can easily see which battery failed and replace it. I obviously would not do this while the system was...

Looking at some of the EVE cells it looks like they are 10%-30% more expensive than the other options I am looking at. They do have a better energy density both by weight and size however this setup will be stored in a storage closet that is climate controlled that has plenty of space so both of...

I did too many hours of research and came across the previously mentioned 3 cells. Shipping and taxes....etc 18650 cells would not be as cost effectively unless I scavenged for awhile and on top of that, the amount of them I would need for 125kWh...making that array would take many many man hours.

Am I able to get 125 kWh for less than $16k including shipping, taxes, fuses and cables?

~$130.00 / kWh. This includes shipping, the cells, fuses and the 47 copper bus bars. I can break it down for just the cells but I do not have that info in front of me at the moment.

I am all ears. I am not dead set on these cells. I am also looking at 544x Calb CAM72 cells as well as 5x Nissan Leaf 153.6V 180Ah (96x 3.2V 90Ah cells from what I could read) packs.

That was my fault, 33P16S is correct. Black is the negative bus bar. Red is the positive bus bar. Red outlined in blue are the 15a fuses. This is only 6 however there would be 33 per row and 16 rows.

Thank you! I will implement that on the negative bus bar however the positive bus bar will not be sitting directly on top of the terminals. I tried to describe how it would be setup in my most recent comment to Steve_S. I will buy a bunch of the Nord Lock washers and flange nuts though...

Thank you for your response! I would only be able to charge and discharge at a rate of ~12A per battery as my solar caps at 20 kW input and my inverters can only pull 20 kW output. As long as the are all top balanced for voltage, which will be done before it is assembled, the Ah rating will...

Thank you for your response! I was thinking of getting a solid copper bus bar, drilling holes where needed for the threaded posts and then drilling small holes on the threaded posts right above where a fully tightened nut would sit and placing a hitch pin through said hole. This would...

Thank you for reading, I apologize for the book but I want to make sure all the information is there for reference. With the surface area of the roof, I will be able to get 80x 250W panels. This will provide 20 kWh of power at peak saturation. The solar panels will be connected in the following...
