Hi. I have the 24kw pack from the X5 but essentially the same cells but just 2 times as much. Have charged yesterday for half an hour with 60 amps so just under 1c and the cells got at max 3 degrees c warmer, no cooling.
If you want to go higher you need to head up the pack before you can push it, but when you are pushing the higher power in you need to start cooling again. See this post with some cell data from a compatible cell:

This is why modern cars want to know when you are going to fast charge so the car can pre-hrat the battery. But I'm also still figuring this out how much I can push the battery without damaging it. And even with the new cars you can tell if a battery is always fast charged or not after a couple of years. So maybe you are fine it you push 2 or 3c into the battery sometimes, but I want to do more homework before I kill the most expensive part of my build.
If anyone else have some ideas about this I'm curious what they are.
Btw, charging with ccs lim and Zombi vcu
