Guess we should stop feeding the troll.
Yes never retort to facts, use internet to flex your career and lack of knowledge with exact product in question. Avoid questions replying to silly ‘e-peen measuring’ post.

Yawn. Y’all too much. Very entertaining.
How many pieces of rivian flair do y’all need to have in order to be accepted around these parts?
All crossbar mounting points used? Curious the cost of entry into the KoolKidKlub.

With the warranty, charge to 100 regularly. Hope for a replacement pack before you’re out of warranty.

If it was bad to go to 100, wouldn’t they limit it? Granted, it’s a new product from a new company and the data doesn’t support it either way. Simple not enough units at higher mileage or total units with controls of charging style/type.

Same like the study about DCFC the data shows it’s much less of an issue and more of a hype/hysteria thing.
I charged my RAV4 EV from 35-50% to 100% every day for 9 years (9.6kW charger). It wasn’t significantly worse when I sold it. I’m also shocked that I always got over 2 mi/kwh, always driving very lead footed. Never get over 1.5 in the R1S, often much less.

I wonder if there won’t be totally different battery chemistries when the warranty is over. I quess I just don’t worry about thing that I have no control over like resale value in 3,5 or 8 years. Will Rivian still be in business?

That’s about what we’ve seen with most other EVs in the last decade+. Exceptions being the: 2011 Leaf and the 1.5 and 3.0 roadsters. They hate life above 70-80% SOC and had significant degradation when the sale happened.
Another data point after having sold 10+ EVs with “high mileage”, only the roadster buyers were concerned with CAC/degradation. Everyone else purchased the EV and enjoyed it.

Wouldn’t the type of charging be a component too? I seem to recall that Level 2 charging is more gentle than the fast charging L3 dumping lots of Kw onto the battery fast.
There data to support that it might not matter. Since the batteries never experience more than 1C.

We always thought that ten years ago for Tesla but all we got was infinitesimally small mah increases per cell and the 21700 form factor in the mainstream. Same lithium-ion pretty much.

Couple questions… I don’t drive much. Maybe 20-30 miles per day. I charge to 70% normally.

Is it better to let it drop to say 40% and then charge back up to 70% or just keep it plugged in every day to keep at 70%?

Second question… I actually use both a 48amp L2 charger and a regular 110v charger. The regular plug is actually adequate. Just depends on which side of garage I park on. I read super charging L3 wears out battery faster but is there a difference between regular plug and L2?

Probably nit picking but might as well establish good habits if it makes a difference.
Can’t answer either question but our commute is the same and I do the same thing if it helps to have strength in numbers
