I like Eneloops as much as the next guy because I don't use my flash very often. I can leave them in my bag and they will stay charged for many months, or even a year probably.
However, if you are a serious flash user who charges their batteries often there are better batteries. Something like a Powerex 2700 will work better at cycling the flash over an extended photography session.
Look at these flash cycle times:

Powerex – 2700mAh
1st 5 Pops Average Recycle Time: (3:86sec)
After 100 pops: (4:61sec)
After 200 pops: (4:88sec)
After 300 pops: (5:10sec)
After 400 pops: (5:48sec)
After 500 pops: (7:16sec)
eneloop – 2000mAh
1st 5 Pops Average Recycle Time: (3.37sec)
After 100 pops: (4:63sec)
After 200 pops: (5:37sec)
After 300 pops: (5:41sec)
After 400 pops: (7:63sec)
After 450 pops: (18:01sec)
After 460 pops: (35:41sec)
The eneloops start out slightly better than the Powerex ones, but look how long the cycle times get after 450 flashes. 18 seconds? I would have swapped them out after 350 or so. Meanwhile the Powerex ones just keep going strong. In the test, even after three weeks of sitting unused the Powerex batteries were still at 100%. So, as long as you top off your batteries at least once a month or so they are better than the eneloops. Except for the initial cycle time which is .5 seconds slower. But after 100 flashes they are cycling faster.
eneloops are better designed for TV remotes, clocks, Xbox controllers, flashlights, etc., things that sit around for a long time unused or only sip tiny amounts of power from the batteries.
There were a lot of batteries tested, and there is a lot of data to sift through. Feel free to make your own conclusions. I was biased in favor of eneloops before I read this test. It seems like a lot of other people are, too. Now I have a lot more respect for the Powerex ones. Especially because of the good performance regarding self discharge. I own a bunch of both brands.
Like a lot of other people, I use a MAHA 8 battery charger.
