Seeing as MSXIV bought these, and the technology has not changed, it would make sense to reuse/ repurpose them. Compared to the consumer available ones, these will be significantly smaller and therefore much more manipulatable in terms of the layout that we want. Note that the cells were said to be quite dirty after the race, although Gochermann provided instructions on cleaning, so they are expected to be relatively clean now and most likely not losing much efficiency.
Plenty of information can be found on the MSXIV confluence page regarding mounting procedure, how to clean, and other information from Gochermann.
