Li-Ion Battery Packs

[NanoRex]

Could someone with more expertise help me out here: Are IMR (LiMn) cells appropriate for use in saber battery packs (For example AW's IMR cells)? They seem to have the same kind of specifications, and are said to be interchangeable with li-ions, but I'd like if someone could verify this for me.

EDIT: Read some posts on FX and it looks like they are. Good to know. For those who don't know, IMR cells are slightly different from the typical Li-ions, usually having lower capacities but much higher discharge rates.
