Thanks for the positive feedback Andy. Not peaking the cells will help with overall life as anything which prevents overcharge is a good thing. A lot of HEVs (Hybrid electric vehicles) which use NiMH (Rav 4 etc) get great overall life by never fully charging or fully discharging. You can also promote the cycle life of LiIon polymer by charging at a a lower voltage (4.1V instead of 4.2V)...
One one though on a previous answer, it's not the voltage during charging that is important.. people get too hung up about it saying "oh my battery is peaking, it's at 10V"... A higher voltage cell during charge can be (1) at a lower termperature or (2) towards end of life, both signify an increase in internal resistance which is a bad thing. What counts is voltage during discharge.
