Yes, the 24kWh modules actually have the text 500Wh printed on them and yes, they are always stacked in even numbers,
that is why the 30kWh pack could combine two of them to increase usable volume and eliminate space that the enclosure uses.
The 24kWh pack has two front stacks of 12 modules each and one rear stack of 24 modules.
Both front stacks have the modules laying flat with terminals pointing to the center line of the pack (and car), from front to back its height is 4 modules, 4 modules, 2 modules and 2 modules. The 4-high is below the front seat, the 2-high is under the rear footwell.
The rear stack is a single row of 24 modules stacked all on top of each other laying sideways with the terminals pointing forward.
As far as I can judge, the 30kWh pack modules were designed to replace the old modules in pairs.
JKenny23 has shot a timelapse of the pack refurbishment last weekend, I will let him do the honors of posting his video.
This may clarify a lot of questions about the layout of the pack. Note that this refurbishment is putting newer 24kWh modules into a 2011.
But I see no reason why modules from a 30kWh pack should be a problem,
other than getting your hands on those modules.
