Experience with AIMS Power LiPo Batteries

Does anyone have experience with AIMS Power 24v 300Ah LiPo Batts? AIMS are quite a bit less expensive than the equivalent Batts from SimpliPhi and Renology. I wonder if there is a quality difference before I buy. Thanks in Advance.

Posting a link to the batteries would be helpful because my guess is that they won't be LiPo but rather LiFePo4, the latter being the safest chemistry in the lithium family.
