I decided to unwrap one of my 36v 5Ah Chinese batteries earlier which I bought off eBay. Mainly to see the size of the cells and assess if the size of the battery could be changed to suit a housing enclosure as I had trouble finding a housing tall enough. My reason for wanting to put the battery into an enclosure was to better protect it in case it should ever accidentally got dropped.
It seems, looking at the fragility of the cells, my concerns are justified.. the cells appear to be made from a kind of soft foil material that is very easily marked and damaged (you can see this from the marks left by the scissors I used to remove the tap on the last picture below).
I wonder is it safe to continue using batteries wrapped in just tape if they are this fragile? Perhaps it would be a lot safer to pad them with foam inside a plastic ABS box...
