A123's have their pro's and con's when compared to li-po packs. The biggest pro is durability. They can be charged at up to 10 amps and you don't need a lvc to protect from over discharge. Their capacity is only 2300mah per cell though. Good li-po cells can put out more power with less weight. A123 cells can be more diffuclt to mount also although that varys from vehicle to vehicle. I went from gp 3300's to these A123 cells and I am very happy with them.
