I have a domestic battery made up of 12 2v cells laid side to side -
so total length 2.15m x 3.18m wide. Cells each have 4 terminals - 2
pos and 2 neg. I intend taking off 2 x 70mm power feeds. On the end
cells only 1 pos and 1 neg terminal is used to connect it to its
neighbour. Should I:

a. take a pos and neg feed from each end.
b. take only the 2 pos feeds from one end and the 2 neg feeds from
the other end.
