not sure what serum is trying to say as if they were all parallel then you would have like a 1s6p pack.

anyway what i have done with my 2s2p pack is make 2 2s lipo packs and then using 4mm gold connectors and cable join the center and a deans T paralleler what this means is should i want to change it to 4s1p all i have to do is remove the center bridge cable and use a series deans connector instead.

I do however think I went overkill with the 12awg cable for the bridge as I am sure that the current through it is probably very low considering how well the cells stay in balance.
