Fisker Ocean batteries

[Remy C]

Hi all! First time poster.

I've recently put a deposit down for the Fisker Ocean and I noticed that the two batteries have different chemicals.

I live in Canada and was wondering if one or the other was known to be better in cold climates?

I'm really more looking for the bigger pack, it says it's a lithium nickel manganese cobalt (NMC) cell chemistry. Is this something proven reliable?

Any advices welcome!
Thank.

. . . batteries have different chemicals

The problem, dealing with cold, is a function of the battery management system characteristics. For the next "n" years, buyers of new EVs are the last integration and test engineers.

My recommendation is look for tools that give more detailed engineering data for your car. Then you can track what happens.

BTW, welcome to the EV club!

My personal experience with my MINI Cooper SE is CATL-made batteries are really capable in extreme cold. I'm guessing my SE has the more established NMC chemistry. It looks like NMC is more energy-dense than LFP (if I understand things correctly), and this comparison article (possibly biased), although not EV-specific, seems to indicate NMC performs better in lower temperatures.
