I have a 24v system comprising:

4x12v 135amp Domestic batteries.

They are connected as 2 pairs of batteries wired in parallel to give a 2 x
24v and then the 2 pairs are connected in series.

2x12v engine starter batteries connected in series

My question. when I connect these to the boat, should I take the positive
and negatives feeds from the same battery/ battery pair or one from each?
Does it matter?'





It may not matter much, Nigel, but the preferred way of doing it is to
run one feed to each series pair, rather than both to the same series pair.

That is intended to ensure both series pairs "see" the same load and
receive the same charging voltage.

Make sense?
