  1. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    I set the truck in shipping mode and locked it and I will report back what it uses per week at the same temp in this condition. I don't have a tender on yet. If I do the tender, I think I'll do a 40-50W solar module with 13.5V max output max power tracker that way its all in the truck...
  2. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    In essence, the overall design architecture is poor and not thought out very well and I do hope there’s a software fix that Rivian engineering will come up to help reduce the automatic sleep mode as much as possible so anyone who cares about efficiency and wasted 1 kWh/day won’t have to do these...
  3. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    Mudito, Thanks. Makes good sense. I’ll try these things, starting with shipping mode, then maybe the tender as well.
  4. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    Yeah, I wasn't thinking to get as extreme as disconnecting the HV battery pack, that seems like alot plus the issues you mentioned. I was just thinking if loads were disconnected from the 12V battery, it wouldn't drain it constantly. 0.7 - 1kW/day is wicked extreme for an idle loss. The tender...
  5. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    Guys, I know its annoying and another hack, but can I just disconnect the 12V battery from its loads and the truck will go truly dormant? I sometimes don't use it for 3-6 or more weeks at a time, especially in winter. Of course, naturally, I understand that I won't have Bluetooth...
  6. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    I am fine with some small amount of energy being consumed to do firmware updates, connect to WIFI, etc., but its got to have a low energy sleep mode where it shuts most of these computers down and only keeps the minimum 2-3W of Bluetooth and/or WIFI or other alive to be alert for a communication...
  7. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    That sounds similar, I guess mine is averaging 0.7% per day. Its a huge drain at 1 kW of battery capacity every single day! That's 1 kWh of electricity every day to not drive anywhere, 30 kWh a month!!! I really hope Rivian works on this and has a solution soon, otherwise I could never...
  8. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    My 2024 R1T is loosing a whopping 21% capacity in 30 days at a constant 40°F when I turned as many things off possible like Gear Guard, locked the truck, closed the app on phone, made sure Bluetooth for Rivian is disabled on phone. I don’t have cellular service activated on truck but it’s on...
  9. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    Why would Rivian’s 2024 on board computers use more than Tesla’s 2015-2021 onboard computers? I would think a decade newer design would be smarter, better faster, better for low energy sleeping. Is the design that much worse? I’d like to recommend this great truck to many other people I know but...
  10. Phantom / Vampire Drain Solution Works! Using 12v Battery Tender

    It’s an innovative way to keep feeding energy into the vampire load but guys (and gals), we are talking about an $80,000-$100,000 state of the art high tech electric vehicle (I had thought I bought), can Rivian please do an update for sleeping that is at least similar to Tesla (that came out...
