So i did a thing...

UsbC is only capable of 20W when connected to 12V ya need 24V to get to 65 W, and thw one I linked is pd 65W when connected to 24v...
Interesting, I've seen some of the 12v cig lighter adaptors offering 65W+ USB PD, they must have a converter to bump the voltage up. I guess thats always an option if you put a cig lighter socket in the creation
 
The pack out dolly has a weight rating of 250 lbs ... Could stack a few two wide if you put the terminals on one of the short sides. Basically snap in an additional 304Ah battery as you need. I have the packout rolling tool box, that may fit 8 cells.

I've been thinking about how many the rolling case would fit since seeing this post. I wish Milwaukee made the base of the tote larger... It's more of a pita unstacking my stack since I added the drawers, I could see it getting repurposed into a battery pack.
Ps - buy a packout wall/floor plate and add your own nicer casters for a whole heck of a lot less than they want for the dolly...
@Lt.Dan thanks for the idea on this, I can see it being incredibly handy, would make a great gift too.

The always list 65W capability, but they only output that when connected to a 24V source.
 
Thank You @Lt.Dan loved your idea.

Pretty much copied your idea for my 5th wheel battery.

I cut a piece of ABS to velcro the bms to. There is 1/8 felt mounted to 1/4 plywood on the bottom, front and back

I assume this is the packout box that was used:

Now on sale with 20% off at ebay:

I just ordered one: $55 shipped including tax

Awesome, and yes that is the correct box
 
Good point.
Seems a better lug placement would be wise.
It would be almost impossible to dead short unless a wire was on each side pointed in and you forced the latch down.
But with my luck that would be exactly what would happen, so even though its near impossible I wanted to put tape on it just to make sure.

You use one lug for those dual 4awg leads for the terminal posts?

If so, what size single lug works with dual 4awg?

I used 2/0 and it's been working fine.

I need to make one of these but I just can't bring myself to drilling a packout tote... I might have to go crappy yellow 😂
 

Looks like dual 4awg is 1awg

But maybe it’s too tight to jam it in there.

did you use 2/0 dies or did you reduce down the dies?

I also have that same jk BMS and trying to avoid double lugs stacking.
 
I used the TH1818 dieless.
... Now I'm questioning if I used a 1awg I have both... Let me dig through photos since I can't easily see it behind the cells.

I used a #2. I bought a pack of #1 lugs just for that but it seemed a little sloppy when put the two wires in. So I tried a #2 and I could get them in and to the bottom.

Interesting, there’s a sun fun kits lubetube video where he put dual 6awg into a 2awg lug and it def looked mighty squished, almost looks like he used smaller dies as it had good sized ears on the lug after it was crimped

Yeah, those type crimpers leave ears.
I like the anvil style better myself.

Maybe its the wire I use. But I had a ton of space left over on a #1 Lug
