Putting together (49) of these this weekend -- right at 5280Ah per battery. Takes one person right at 1hr 15 minutes to go from unpacking-loading-testing.

Decimal point mistake maybe? 16s LFP with 5280Ah would be 270kWh per unit... 27kWh per unit maybe? Even then every cell needs to be 528Ah and frankly they don't look that big. 314Ah maybe (16kWh/unit)?Putting together (49) of these this weekend -- right at 5280Ah per battery.

Even with "only" 16kWh per battery that's almost 0.8MWh storage.![]()
That’s because the bottom cell is about 1/4” narrower than the top cell due to 7 brothers pig piling on it.
It's not a decimal point mistake, OP just doesn't understand batteries/ohms law.Decimal point mistake maybe?
Many oems are stacking the cells like that, but it still makes me wonder what all that weight stacked on top of the bottom cells might do after several years of expanding/contracting with the soc.That’s because the bottom cell is about 1/4” narrower than the top cell due to 7 brothers pig piling on it.
OP is EE, so she/he should know this.It's not a decimal point mistake, OP just doesn't understand batteries/ohms law.
They have 16 x 330Ah batteries and they think that means it's 5,280Ah total (16 * 330 = 5280), when it's still 280Ah it's just 52V not 3.2V.
What is holding the cells in? If it tipped over onto its front, what happens to the cells?Official video here :
I mean, are they though? Everything about their posts is sus. Why do they keep spamming the same thread over and over (there is this thread, posted Saturday, this which was posted on Friday, and this which was posted end of December. Are they just desperate for attention, or full of shit? It's honestly hard to say. Why in the December thread did they say they are using CATL cell and in the other two threads they say they are EVE? Everything about OP's posts set off alarm bells, don't believe every rando on the internet.OP is EE, so she/he should know this.
I see no evidence in their posts that they have anything greater than a grade 12 education. Posts are riddled with small errors that anyone building batteries commercially should never make. Are they even female? I doubt it.IIRC Ghostwriter does power for drilling and other field industry sites that need power on a "temporary" basis where there's no grid. She's been around a while.

In any case something is wrong there, but then we all make mistakes. Well, at least me. Frequently.
NO I DON'T WORK FOR EEL OR CATL ...
We are building out approx (60) remote communication system shelters which will basically be using (1) SOLARK-15, (3) EEL VERTICAL 54V 314 Ah LiFePO4's, and (48) 390W solar panels.
This will all be located in a 8x10 Cargo container which will be transported by truck or helicopter to where they need to go out here. The original intent was to make it all fit in one container but when they increased the SOLARK size, and then extra batteries, we will now have to have a separate cargo container for the Panels and generator. The generator is a 25kW diesel...
