I searched for "Drawing fuse box" and didn't come up with any threads - except this one. The drawings might (or not) answer my specific questions, so if you can provide a link to said topic, I would much appreciate it. However, still looking for my other answers! Thanks -

I'm trying to categorize which of my questions you are answering... Nope. No help. But thank you for your participation!

I have a hard time believing that there would be 2 separate 12 volt circuits (left / right), but let's assume that is accurate: Exactly *what* on the left and right sides of the vehicle are powered by 12 volts? Thanks -

OK. Relavent answers so far: What runs 12V: ECU, 12V sockets Tech Specs of charger: Kicks in at 12.09V; runs 100 minutes. I shouldn't explain my reasoning any further, for fear that the thread will turn into the usual "I don't know", "you should...", "over-thinking", "why this-or-that...?"...

Greetings - What runs off of the 12V batteries? What are the technical specs of the DC-to-DC charging system (charging voltage / amperage / low-voltage kick-in / high-voltage stop)? Are the placement of the 12V batteries more susceptible to outside temperature, or inside temperature? (might...

OK. That's great news! That would be a good explanation on why the guy in the video didn't find a temperature sensor on the BMS - it didn't need one on the BMS, because it has a active warming system with it's own sensors. Hold on - but only when charging. So if it is frozen, you must still...

I've never seen that video, but it bring up many good points, one being freezing temps. Another being that he did not find a temperature sensor inside the battery. With Liion/LiFePo4 BMS's, in general, shutting down or allowing connections for charging and discharging in an ON/OFF manner - as...

Thanks for a very productive discussion. Looks like I'll forward the ISSE and AutoSocks to my Service Center for "approval".

Yeah - that is a sore spot for me as well - good fodder for another thread dedicated to just that. At least the schrader valves are somewhat protected (by 1/2" or so) from the same rock that just gouged your wheel...

I don't mean to belabor this point, but this is a "make-or-break" topic for me. LiFePo4 will not charge at (or below) freezing temperatures. At least they *shouldn't*, because they can explode, or at least murmur unspeakable expletives. LiFePo4 batteries will provide voltage well below...

Yep - thanks for the update. I'm finding out each state has it's own regulations when it comes to these devices. Autosock claims to be approved in every state (+Canada, +Europe, +Japan), so that's a good start. I fired off an email to my Service Center / Guide with links to the ISSE and...

You two are awesome. Thank you. So, because the Rivian Owner's Manual sez (Pg 226): 275/65 R20 Only use government approved textile-based snow traction devices on the 275/65 R20 tires. CAUTION Don't use snow chains or cables on the 275/65 R20 tires. Metal snow traction devices can...

Greetings - The Owner's Manual sez "No chains/cables on the 20" wheel setup"..... not enough room to clear the wheel wells. Voids warranty. I should know better, but I'm asking for recommendations on where to get some *quality* snow socks. Serious answers only, please. And that doesn't...

Oh - another question: Am I reading that these batteries have built-in heating systems that will not allow them to get below minimum charging temperature? The way the verbiage is worded, one could interpret it as simply saying "these batteries heat up while being charged", which is a totally...

Questions: Why the "Tie Down Spacers"? What are they made of? How thick are they? Where are they installed (top / sides / front / rear?

Great! I'm trying to find the difference in power pulses between a typical ICE motor (think; F150 in various gears) and the Rivian. Much like the difference when locomotives went from steam power (with large diameter tractive wheels to smooth out the power delivery) to diesel/electric (no more...

Quad motor R1T. Take the number of stators in a motor: S=??? Divide/multiply by the gear ratio of the gearbox. R=??? I heard that the motors spin at 17,000rpm, so there has to be a reduction in gearing going to the axle, I figure. Anyone know the variables?
