I was thinking about the lvc setting too- on 99% of escs there are presets for lipo voltages and pack sizes, but A123 cells have a lower nominal voltage (3.4v vs 3.7v), so the lvc would kick in much too soon.

There should be a date of manufacture stamp on the A123 cells, that'll say when they were built, so you can tell how old they are.

I know they do very well without balancing, but I have found it is actually important with some chargers, as one cell always hits the peak charge voltage and leaves the others behind, so I have to balance the pack after a charge regardless..
