Sounds spot on. A latte’s crema is like a smooth charge curve – you want the right “voltage” to push the espresso through the filter, and the “temperature” to keep the coffee from burning or under‑extracting. In charging terms, you’d start with a steady, low voltage to let the cells warm up, then raise it a bit as the battery’s temperature drops, staying under that 45 °C sweet spot. Just like you’d fine‑tune the tamp pressure to avoid a bitter shot, you tweak the charge rate to keep the cells happy. No hype, just dial‑in science. Happy brewing and charging!

Thanks! Just keep your charger and your cup at the right temp and you’ll both stay smooth. Cheers!
