I monitor the cell voltages and they are always the esame within reason below 4.20v after discjharge but the msg comes up often on 1C, 2C or even 50 ma settings.
Thanks for the help.

The pins and sockets on the balance connectors are subject to minor corrosion. (This is true of all brands of charger and connectors.) When a little corrosion occurs the charger cannot see the true value of the individual cells and posts a Cells Do Not Add Up error. Cleaning all the contacts on your charger and balance connectors with an electronic contact cleaner should cure the problem. I use DeoxIT D5.

Had this same problem also several years ago until I replaced the battery adapter after speaking with FMA. I mistakenly blamed the charger but since the new adapter have had no problems. Cleaning the pins and sockets on battery and adapter was not successful for me but you may experience different results.
