EBL has some Li-Ion AA rechargeable batteries but they don't list the maximum discharge rate. As far as I know it's a 3.7-4.2V Li-Ion cell with built in BMS (battery management system) which regulates the charging as well as the output voltage. The output voltage is a regulated 1.5V and thus it's 1.5V regardless of the current draw but of course up to a certain current which they don't specify. Also they rate their battery as 3300mWh which comes out to an equivalent of 2200mAh. Which is not incorrect but people may mistaken for a high capacity if they don't read carefully.
I think it would be good for some low drain devices but I think it's not good for flash.

I wouldn't purchase them. The bad outweighs the good. They can be dangerous and virtually impossible to dispose of them safely.

Is it any more dangerous than camera batteries and power tool batteries?

NOPE!

The maximum discharge rate EBL told me is 2A so it won't recycle a flash as fast as NiMH battery. However, there is regulator inside the battery so the voltage is pretty much constant 1.5V regardless of the current draw (must be less than 2A). I think they are good for things where alkalines would leak. It has slower self discharge rate than even Eneloop so for low drain devices it would be good.

I bought a pack of "Deleepow" batteries similar to these. I tried them in a Dremel tool, and right off the batt (pun intended) one failed, internally shorted the protection circuit, and self-discharged with plenty of heat released. It would never charge again. Too fragile for me.
