Battery date is 16 january 2007
cell group 1 is bad 0.25v
cell group 12 is bad
cell group 13 or 14 is bad (can't tell which from you pictures)
given the age of the cells, I would replace with new along with the worst other so called good pack, this way at least you will have two good batteries.
when removing batteries, always remove the positive wire first, starting with the big red one and go around in sequence.
DON'T LET ANY WIRE TOUCH ANYTHING ELSE
when you have made, pruchased your replacement cells attache the wires in reverse order, starting with the big black one.
If you're not really sure then let someone skilled do it, it'e easy to kill your bms board...or start a really big fire.
hope this helps.........
