Review: Turnigy Accucell 6 Hobby Charger

I bought this charger a few months ago, I know exactly what it is capable of. I charge my RC toys LiPO batteries with it.

I also charge my LiIO cells with it using the LiIO program but this program stops at 4.1V. I just want to know if anybody knows if there is any problem charging LiIO cells using the LiPO program.
