Two different capacity batteries connected in serial is a NO NO.
They should be the same capacity and some say ideally from the same production batch.

I found that cells can have a 0.1V or even more difference at the end of discharge without any problems.
If you are worried you can programme the LVC cut off values to be say 3.2V, 6.4V etc etc.

I used to do this but as my batteries are usually only 75% discharged, I just use the default values.
