4 x 105Ah cells@3.2V in parallel = 420Ah@3.2V battery pack.
This add is knowingly misleading, but correct.
yep...this is why it sooooo difficult when buying from aliexpress/banggood/etc. as the level of "marketing speak" is far beyond what most people are use to hehe4 x 105Ah cells@3.2V in parallel = 420Ah@3.2V battery pack.
This add is knowingly misleading, but correct.
Can you read the label on each cell ?
It is the weight and dimensions of 280ah cell.
My point is the label printed on each battery.I can see your point, but the battery appears to be configured in series, not parallel in the picture.
LiFePO4 batteries typically have an energy density of 180Wh/kg, these 420ah cells have an energy density of 260wh/kg, Unbelievable!
As I know, the brand new grade A battery cells always have a higher capacity than the rated capacity, just like this test report: https://www.evlithium.com/upfile/Test-Report-of-400Ah-LFP-Battery.pdf, the 320ah PWOD cells, 280ah eve, Lishen 272ah or CATL 302ah, all have the same Appearances and same size of the aluminum cases, but the price of the 320ah cells is not like the quality "A" cellswhat do you think about 320ah PWOD cells ?
they weight 5.1kg so that is more like a 280ah cell, right ?
PWOD seems to lie , anyone knows if someone did capacity tests on 310ah PWOD cells ?

OK, now explain why each cell says 420Ah when bought in quantities of 4 and 16 == 20. That is how many I bought.4 x 105Ah cells@3.2V in parallel = 420Ah@3.2V battery pack.

Yes, the label says 420Ah and the weight is 5.1 Kg. The dimentions are 201mm high, 72mm thick, 173mm wide +- 1mmCan you read the label on each cell ?
