This is a monster cabinet that weighs 7720 lbs. Dimensions are around 8 feet tall, 4.25 feet wide, and 4.25 feet deep. This will have to ship on a flatbed. You will need a forklift that can unload it. These have never been used and the cells are all in perfect condition. This comes out to just...

Yes,
That's a great deal. But also a lot of work.

I think it looks like fun, personally.

Dangerous fun. But still fun.

I'm in love, as far as dangerous though, they don't look to bad, 8 separate 48s packs wired in series, but if you look at the packs the all have what looks to be an isolation block on the front. (orange square with pink cover)That's usually a pullable fuse that completely isolates the pack. so pull those, then remove the interconnects then pull the 48s packs and separate into 3 16s strings. add a bms and you have a 43kwh 48v pack.

I think it's more like 24 packs in series to make the 1200v. I'd be afraid to open that cabinet.... but im not trained to handle super high voltage DC.

Another problem is that it's huge and probably won't fit indoors so you may end up needing a long (expensive) battery cable run to the inverters. In my case it would need to be ~60ft.

You're supposed to refresh all the battery websites every 5 minutes

Switched to a different design. I have never seen any defects or had any of them test below capacity. The cells are still in the crate from 18650.

To complete my planned expansion. I still need 256 more cells. This deal would be perfect. If the timing was right.

You’re gonna be caught up with me soon! 272 plus or minus.

300kwh storage is the plan.
But some of it might become double duty, with the truck build.
