CATL 16S 11kWh battery Pack, is this LiFePO4??

[GibbFx]

Hi everybody,

I follow the forum from Italy, and sadly from Europe is almost impossible to buy Server Rack Batteries ( from signaturesolar, I mean).
To tell the truth, this forum is a huge source of informations for me!

In my 48V system, I found an interesting solution from CATL; according to seller it's a 16S 11kWh pack composed of prismatic cells.

Has anybody any experience with this battery pack??

Any clue if the modules are LiFePO4 or other kind of chemistry?? (in some site I found it could be Li NMC, but from the pictures looks primsatic cells... I'm a bit confused)

Can anybody help me out with that??

Thank you guys...

If it is 48V nominal and 16S then yes it is LFP.

Ok, maybe this can give some help:

it is rated:
Nominal = 3,67 V/cell (58,72 V/module)
Max Charge = 4,2 V/cell (67,2 V/module)
Cut off = 2,8 V/cell (48 V/module)

from this data doesn't look LiFePO4 I think, but still... they look so prismatic...

The higher voltage would indicate its Li-NMC.

Check out nkon.nl or fogstar.co.uk - Both will supply to Italy AFAIAA.

3.7V nominal per cell is definitely not LFP. Also that's almost 59V nominal, at 67V at max charge - not going to work with a 48V system.

LFP nominal is 3.2V (so 16S is about 51V nominal).
