Right now, they're the power source of choice for very small EDF's (Wemotec microfan sized) and in the near future, they may well become the hot ticket for all EDFs. They presently cannot deliver the high amp discharges like Ni-Cads and now NiMH's, so you have to build paralell batteries to handle the draw. This makes them a bit expensive for the larger fan sizes. However, the prices are coming down and the amps thay can supply are going up. They well may become the hot ticket, at least until a new technology emerges.

Not totally true. Yes you need to build combination parallel and series packs, but there are several people running them up to 65 amps without issue.
