Trev,
I was hoping the old cells were going for scrap and i might have got a good deal on them.
Nice work you done on the ally fabrication, im not sure if i understood correctly with one battery end terminated to the ally box (Gnd i guess) if so i would warn against it due to corrosion of different metals at the connection, ally is bad for this and you will get resistance over time.
The Relativities work well on maintaing cell balance once the pack is stabilized within a few 100mV difference, but can take some time to bring the cells into balance, and im guessing is why you have doubled them up.
Perhaps you might need to ask to trial some of the later cell balancer design thats still under testing
as they appear to have a much faster equlization time.
Pete.
Sometimes it just works
