I posted some analysis of the MME pack and it's current capability, here: https://www.macheforum.com/site/threads/mach-e-battery-reverse-engineered.511/page-2#post-67601
I have not been able to find any detailed information of the pack, e.g. cell datasheet, to confirm if these calculations are correct, but they should be close based on my experience with supporting OEM pack development.
The MME pack is built with LG-Chem cells, while the F-150 Lightning is built using cells from SK Innovation. The capacity is also much bigger, so there are likely many more parallel cells, therefore able to accept a higher charge current. I would say the Lightning will have a completely different charge curve than the MME, likely with much more area above 100kW. The 150kW peak charge rate is likely due to sharing of onboard DCFC modules like the pack relays and other BMS components.
