So I ran across this today:
Power Queen 12.8V 410Ah LiFePO4 Battery, 5248Wh Energy Lithium Battery Built in 250A BMS
Price is more than double the 200 Ah, but the size is the same.
Weight is 36 kg at 410 Ah. The 200 Ah is 22 kg.
Picture shows 8 cells, so 4S2P cell config.
Here is where I am a little skeptical.
Is it really possible to pack that many cells in the same case as the 200 Ah versions?
If so, while the price is a premium, it would allow more energy density for tighter fits.
Part of the skepticism may also come from reading the posts about fake 420 ah individual cells.
But the drawing doesn't show 4 big cells, it shows 8. So it should not be really related.
