MMM Voltage-- Is this too much?

[BL_RV0]

I was wondering if I could run 8s Li-Ion at 3.2v/cell nominal fully charged. The total voltage would be 25.2v. Is that too much? Also, charging the Li-Ion, should I use the A123 charge or the LiPo charge on my 1210i? Maybe set charge fullness to about 95%? Any ideas? Also, is balancing these cells as important as balancing LiPos? Here are the cells.
