    My car has 1 battery, BT connected via ODB2. Brand is Battery Tender by deltran.
  2. 12v second battery overcharged after using ODB port battery tender?

    I think the naysayers misunderstand the reasoning: Scale. I have a G1 R1S, and lets say I take a 2 week vacation. Parked over 14 days (70deg in garage) I lose 28% of the main battery (=70mi of range). When I get home the last thing I want to do is charge it. You may rebut with: just keep it...
  3. Installed the new Pirelli Scorpion XTM today!

    I am at 14k on OEM 22s - G1 Quad, I don't want new tires from a cost avoidance measure, but these are def on my radar.
  4. Apple Watch Integration Coming Soon Says Software Chief Wassym

    This data looks wildly inaccurate. No doubt Apple is the market leader, but fitbit falls off in 2021, and there is no mention of WearOS, which covers many mfgs now. Where is Garmin in this? I wouldn't expect Pixel Watch to have more than 2% but it doesn't even show up, but something called...
  5. Installed the new Pirelli Scorpion XTM today!

    Can we get details on treadlife and price point? I was going to switch to 20"s for a better ride quality, from 22"s, but if this improves ride qual, is snow worthy, and doesn't reduce range drastically, count me in!
  6. Vampire Drain Fix: How to solve in under a minute (indoor or outdoor)

    We are in an urban setting and live on top of the R1 as it is. Ok will give this a shot. Mildly annoying, but I suppose we do carry our Card Keys in our wallet, and as long as I can use the app buttons and features, I could live with this. Does the Gen 1 Key Fob do this too? It was at home...

  8. Vampire Drain Fix: How to solve in under a minute (indoor or outdoor)

    Anyone see a risk to running the latest update while on BT? I can turn off BT remotely. Might just wait

  10. Vampire Drain Fix: How to solve in under a minute (indoor or outdoor)

    Update: Really good news, the past 24 hrs, it has been sleeping, with ZERO! VD. 255mi 85% no change. My outlet's energy monitor shows 600kWh utilized in 24 hrs. Seems a tad high, but MUCH lower than 2kWh+ I would see from VD. @$0.48/kWh this equates to a substantial savings in both energy and...
  11. Vampire Drain Fix: How to solve in under a minute (indoor or outdoor)

    It definitely was not sleeping in Rivian app last night per the app. (All doors shut, but windows down) ElectraFi noted "idle/sleeping" state. Here is the current state (from 12:00am on) GG is off at home. Typically I lose 1-2kw per night.
  12. Vampire Drain Fix: How to solve in under a minute (indoor or outdoor)

    Not sure it is entirely working, but I will monitor over a few days. Device is set to AGM 12V. Parked at 264mi 90% at 5pm, plugged in the BT. This morning I am at 261mi 88% Tracking since 12:00am (now 9am)
  13. Vampire Drain Fix: How to solve in under a minute (indoor or outdoor)

    Installed! Open to some thoughts, see below with light questions. Has anyone run this out the door and closed the door - or just pass through an open or vented window? The tag on BT, says only for Lead Acid batteries, but the device is in lithium mode, confusing. 12 V - Do I want AGM...
  14. Poll: Would you buy your Rivian again?

    I voted no because of quirks at price point, mainly VD. Do I want an R3 - yes.
  15. Vampire Drain Fix: How to solve in under a minute (indoor or outdoor)

    Closing the bear discussion out, my campsite (Pinnacles NP) only had raccoons, and yes I agree, bear bag is best.
  16. Vampire Drain Fix: How to solve in under a minute (indoor or outdoor)

    Before I jump in; I see some commentary on the 2amp version working, what's the reason for going 3a? Heck BT has 800mAh versions
