nah, i don't know that i could detect that magnitude of difference either, but i do know that it's magnitude is along the same lines of the different stages of batteries being offered. and, for some reason, i have been convinced that good cells are a must. .010v/1.170v is approximately .09%!
see what i mean? i guess if i am going to buy high end cells, i'd be reluctant to use any type of "smaller" gauge wire, if only from a numbers standpoint.
