Battery packs, a decision factor?

[alyuan]

I have a SR+ and a M3P on order. I was weighing between a second SR+ and a M3P, decided on the P because of performance (duh) and a better sound system.

Knowing there’s a different battery pack between SR+ and the rest, it got me thinking if the battery pack is a decision factor to one’s purchase?

I see LFP becoming the ’diesel’ in the EV world, less degradation, better thermal stability, can charge to 100%, a simple form of electrifying compared to LG/Panasonic packs. Having experienced the LFP batteries, I prefer it in my P if there’s a choice.

I got a SR+ and felt that the battery was enough as my limiting factor is the weakest bladder in the family. For me ride quaity was a bigger consideration hence the reason for perferring the 18" wheels.

There isn‘t a chemistry choice in LR and P - if you want the longer range and/or higher performance it comes with a Li-Ion pack, since LFP batteries don‘t have the energy density.

LFPs are the obvious choice for Australia.

the advange is great heat resistance, great protection from degradation, ability to charge to 100% all the time.
The disadvantage is poor cold performance. Australia doesnt get cold, even when you guys think its cold here.

The LR battery turns very quickly into a SR battery here anyway thanks to degradation.

no it doesnt. The LR will always have longer range than the SR+

Car is a city car so range is not an issue. It does seem less attention is needed for LFP, and the ability to charge many many cycles?

given that I have 16% degradation and another guy here 20% degradation and LPO batteries dont degrade that heavily I beg to differ.

Having 368km at 90% is no joke.

FWIW - and it's probably not a lot - think about resale in say 6 - 8 years.
Any battery is going to degrade to some extent. Anyone looking to buy a used EV will obviously have his intended range in mind and many won't want a huge range, just the right price point. But you don't want to be offering a car for sale with a lowish range and that will depend on what you get to start with. Here in Oz buyers will probably be looking at a longer range than elsewhere so I would go for the largest battery now.

I want a Powerwall 2 with LFP batteries.

 

[Candleflame]

The issue is that in 8 years the SR+ will have a higher range than the LR.

The LR will always have longer range than the SR+

Science suggests otherwise

Recent independent degradation tests of commercial lithium batteries prove - LFP chemistry is safer and has a longer life-span than NMC.

Hopefully Powerwall 3 will be LFP. Else there is AlphaESS

My 20 (approx) month old Powerwall 2 has LFP advisory labels…

Have you got a photo of those labels? Curious if Factory or Installer labels.

That makes sense using a better battery but why not tell everyone?? and lower the price!

Ah OK, suggest your installer fitted the wrong label kit, though happy to be wrong.

Possibly, although it has always charged to 100% (in fact I don’t know that there’s a way to limit the maximum charge?) every day as is the normal recommendation for a LFP pack.

Forget the lab, This is the real world degradation of NMC batteries in Tesla's.

About 9% after 250,000 km.
LR starts with 25% more range than SR+.
And the SR+ will still degrade.
