I may be working on a similar battery pack, for a working bike. I have one 4P cell that is practically useless and two that are at about half capacity - the rest are OK. Would you consider selling yours for use as replacement parts? I'm in Toronto.

What make and model are the cells?

You could do a 14s3p pack for 52V 6.4Ah, but if the cells are only rated to 5A then it won't be a very powerful pack. Could be a bit flamey :? .

Another option would be a 10s4p and have a 36V 8.5Ah pack. Would make a good backup pack for a 36V rig.
