Is there a big difference specs wise? Would it be worth paying an extra dollar for possibly more range/speed (mostly range on 10s) or just stick with the 15a model?
I have the 2070c in a 12s 2p pack for my hummie haya, still setting it up so I haven’t really tested them but if you are going for a smaller pack (less groups in p) then do the 2070c and if you are doing a larger pack (more groups in p)go for the 20700
20700B’s are a great cell. if you’re running 5P+ you’ll be capable of 75A batt which is generally acceptable as enough unless you want insane amps for uphill racing or something.
