  1. Ohmmu Announces BT19 Sodium 12V Batteries for Rivians: Thoughts?

    Except being charged when freezing. LFP is just awful in the cold. Tesla uses LFP 12.8v batteries but they are also heated. This is sodium's biggest advantage over LFP right now as it can be used in sub-freezing temperatures without babying or heating it, and they maintain their "capacity"...
  2. A good time to own an EV - Gas Prices about to go nuts [LOCKED DUE TO POLITICS]

    You really went another direction in responding to my comments directed at those taking joy in the situation from their electric perches. You say "no one has an agency of zero" and then turn around and say "it's too easy to be focused on individual behavior." That sounds like a cop-out for...
  3. A good time to own an EV - Gas Prices about to go nuts [LOCKED DUE TO POLITICS]

    I don't think "well-meaning upper middle class" means what you think it means in this thread. Being condescending to everyone who doesn't own an EV is as narrow-minded as those who completely refuse to consider owning an EV themselves. You do have a point that "the math doesn't work" for a lot...
  4. Subaru Dies Before My Number Comes Up in the R2 Queue

    Agree with this. Calculate the increased value of the working Subaru vs. a non-working one, and the cost of repairs. You're almost certainly still going to be in the red, but that's just bad luck for you. Having a car with a new transmission should give you the confidence to keep driving it...
  5. A good time to own an EV - Gas Prices about to go nuts [LOCKED DUE TO POLITICS]

    Not sure why there are so many glib people here. Even if you fill up with electric and power your home with solar, the ripple effect on fuel prices raising the cost of everything else and depressing the economy is just plain bad news for everyone.
  6. Upgrade from 50 to 60 amp circuit to get to 48 amps of charging? Have 2 EVs.

    40A puts about 6.7% per hour into the max pack. You're never charging from 0-100, so a more realistic (but generally rare) estimate would be 10-85 which takes a little over 11 hours. I have two Tesla UWCs wired in series on a 50A circuit. 40A is plenty for both of our cars.
  7. A leaking damper is... Acceptable?

    I read that someone here bled it without special service equipment, but I don't know how. I think it must be done with a vacuum pump and software. It's true that the hydraulic and air systems don't "mix" but the airbag/damper is one assembly. Sometimes an air leak is somewhere other than the...
  8. A leaking damper is... Acceptable?

    What does the damper look like? Does it have fluid running down the body and an accumulation of sludge like this? These were from my Model S. I could feel the driver's rear corner was way underdamped, especially over harsh bumps. Tesla replaced it under warranty (after they first tried...
  9. You've Owned An EV For A While Now. How Have Your Charging Habits Changed?

    I charge a bit less often than before, but EVs' horsepower is generally less sensitive to voltage now than they were a decade ago. My 2015 P85D had noticeably more power at higher >80% SoC. I always charged to 90% and plugged in as frequently as I could. I care a little less about speed these...
  10. A leaking damper is... Acceptable?

    Don't forget to include the LX600, Tundra, and Sequoia that use identical or near-identical variations. The huge volume of these models help to depress the overall cost of the dampers. I still agree that the price for these is bonkers, but the other part of the delta comes down to the...
  11. R1T 12v battery replacement every 2 years?!

    Lithium typically carries a lifespan whose charge/discharge cycles are an order of magnitude greater than lead acid. Even if you get an early 12v failure at 18 months, that's 15 years for lithium. LFP does need to be heated to properly charge it below freezing, and Tesla does actually heat...
  12. R1T 12v battery replacement every 2 years?!

    And the cost of having to replace these batteries on vehicles under warranty. And the cost of reengineering the original dual 12v setup. And the cost of reengineering the 12v again to move it under the passenger seat so it doesn't take over an hour to replace. Like the cheap packaging they...
  13. R1T 12v battery replacement every 2 years?!

    They say it's not intentional like they accidentally made it prohibitively expensive to get access to the service tool.
  14. R1T 12v battery replacement every 2 years?!

    It's bad enough that the lifespan is so poor, but the biggest "f you" from Rivian is that you can't completely do this yourself since they require you to have access to the service tools. I had the battery replaced in my Model S by Tesla in my driveway for $200.
  15. Launch Mode - Times

    I had a loaner 23 quad so I tried it out with around 70% SoC on the stock 22s. Dry roads, about 45 degrees. 3.4s. Haven't tried my own truck yet.
  16. Ocean Coast Interior Question

    I occasionally spill red wine on my drive into work, but the ocean coast interior always cleans up perfectly!
  17. GEN 1 R1T Home Charging Frustrations

    3 phase is weird. You get 120v on each hot (as seen) but only 208v combined (as seen) since the phases are 120 degrees out of phase and not 180 degrees like you see in a house, so the peaks of each phase are not seen at the same time. https://en.wikipedia.org/wiki/Three-phase_electric_power...
  18. Brake Systems Replacement Costs - Is this normal?

    That's good to know, I figured this would require the service menu to cycle things.
  19. Brake Systems Replacement Costs - Is this normal?

    For reference, replacing a rear air damper on my Model S back in 2022 was $1800. I've seen Model S brake prices quoted at twice what Rivian wants, but that's still too high for something so simple. $400/labor and $1152 for parts. You can find a set of ceramic pads and coated rotors for $370...
  20. Need advice on Coast to Coast relocation towing

    I don't think those numbers are realistic. In the winter, I get 1.87mi/kwh while averaging 70mph on flat terrain with no weather - and that's with a dual motor. DCFC stops can be pretty expensive, longer, and more annoying while towing a trailer. Are you also budgeting an additional hotel...
