I have been using the Eneloop lithium batteries in my 580EX for a year without a problem. I shoot events and go through a three hour shoot averaging 350 clicks usually with one load of 4 aa batteries and have never had a problem with overheating. I realize that this is just my personal experience with one particular brand but thought I should share.

There is a difference between Lithium and Lithium-Ion batteries. Some battery manufacturers sell Lithium batteries claiming they last longer than the old style battery. Lithium batteries are referred to as 'Primary' cells and should not be recharged, Lithium batteries hold a higher charge and so theoretically should last longer. Lithium-Ion are 'Secondary' cells they may be recharged. Batteries like Eneloops and PowerEX are Ni-MH batteries. Nickle-Metal Hydride store their charge in Hydrogen. One big advantage that Ni-MH have over Lithium-Ion is that Lithium-Ion batteries don't fair as well in extreme temperatures, however Lithium-Ion batteries are not as susceptible to the 'memory effect' which affects the battery when recharging it before it is completely discharged.(They tend not to recharge fully) At any rate I use Eneloops and PowerEX and they seem to be fine , my flashes have never gotten warm to the touch either.

Thanks fotowerks. Are yours the rechargeable type?

Every description I've seen in reference to the Eneloops batteries is that they are Ni-MH and not Lithium-Ion unless an older generation of them was.

I, too, will heed the warning.

Interesting. I've been using them in my Speedlites for several years and no problems. I'm not going to stop using them now.

My bad. They are NiMH.

Sorry for the bad information. Though I do use these batteries, they are NiMH as has been pointed out not Lithium. But they are great batteries just the same.

I had heard a similar warning about Nikon flashes. I ignored it until I noticed that my SB600 got very hot and was very slow to recycle. When I removed the batteries(Energizer Lithiums), they were very HOT and the outer plastic coating was split and distorted. When I tested them they would only read 1 volt on my VOM! Luckily my speedlites sustained no damage and I have discontinued using lithium batteries in all of my equipment.
