The individual cells can be found here:
and a complete pack assembly is offered by jonescg viewtopic.php?f=31&t=38252
Of course you can simply get any LiPo packs and connect them in series/parallel.
My pack is 14s2p so a common 16s LiFePO4 (58.4Vmax) charger can be used. It's in 2 halves, aka 'riding saddle' arrangement. Each halve is 140 x 120 x 50mm and weights 1.7kg, for a total of 3.4kg. Not sure of run time yet, should be able stretch to 50km/2hr ride. I can always make the pack bigger (14s3p or 14s4p) or just carry another one in the backpack.

But if you did notice that you had a weak cell in a paralleled group of 2, you could remove them both and test them to see which is the weak one.
I think i'm confusing myself now

Here are a couple of photos of the pack, note polycarb corners. 750ml bottle for scale. White plastic was hot-formed.
