Has anyone ever had their Canon flash overheat during heavy shooting? I am using lithium batteries.

While shooting a wedding and reception, everything needed flash. I use lithium batteries in my flash, but they overheat and I must change them out with fresh ones. Is there another kind of battery that works better or is this just a fact of life that I must be prepared for?

I didn't even realize that they make lithium AA batteries. I'm pretty sure I've never seen one.

As I stated above, lithium batteries are good in places where you want them to last a long time under harsh conditions. For example, I put them in the outside temperature sensor for my home wireless thermostat system. Just don't ask them to put out a lot of current in short period of time, like say, a flash!

I don't think it's quite that simple. There are commonly used lithium battery packs that clip onto your belt that can be used to power a flash. They deliver power a lot faster than the four NiMH AA's in the flash unit itself, yet they don't get hot in normal use.

I am talking about these. As I also said above, don't confuse *re-chargeable* Lithium's with non-rechargeable Lithium-Alkilines. The OP has not told us what he is using.

Well, all of this talk about batteries is making me nervous.  What about the B&H "Watson" batteries, which they claim are NiMH?  Are they any good, you think?

I've used B&H's previous NiMH house brand, whose name escapes me at the moment. They were marginally better than Radio Shack, but not nearly as good as Eneloops.
