What pros or cons would I have using NiMh rechargeable batteries like these:

http://www.all-battery.com/8pcsofcsize5 ... 90419.aspx

versus just using Duracell batteries, other than saving money on buying batteries each week?

They are being used in a Sunpak 622 flash.

How good is the lithium battery packs for these flashes?

Cost savings over time for sure. I'd also imagine they won't drop off like standard batteries. Can't say I'm familiar with that brand. I use Powerex (http://www.mahaenergy.com/powerex-batteries/) and eneloop and have been very happy with them. They don't decay like regular batteries (although you don't have as much warning when they will die) and being rechargable you can sometimes salvage a battery that is under-performing.

If you can't fix it with a hammer you've got an electrical problem.

cons
extra weight to hold

better choice would be a used quantum turbo

Being a 622 user you would get more flashes out of the turbo , without changing batteries during the night

Would you expect the recharge time to be any better or worse with the NiMh rechargeables vs. standard batteries? I know that most rechargeables are only 1.2 volts, so I'd only have 4.8 volts instead of 6.

I'd love to go with something like a Quantum. Right now my budget says no.

I don't know what the batteries cost that you would like to use instead of Duracell

But the rechargeable batteries will work and recycle okay I used 8 of them and made it through the night .That was using film so I didn't shoot more than 72 photos on one night.

Might if you call around you could find a used quantum for 175 dollars - 200

not sure on which camera you have you might be able to shoot at a higher iso and not have issues with battery life

I also had two battery holders so I didn't have to fiddle with the batteries in the dark

Heard a couple of recommendations for Powerex by "experts" on line. I got a Turbo this season and so for its been great!

NiMh with a high mAh rating would be better over standard batteries. Don't worry about the voltage when comparing rechargables to non-rechargable. I've used the same set of 4 rechargable AA batteries for 2 weeks with little to no change in performance. That would not happen if I was using a non-rechargable battery.

I use PowerEx as well. Buy 16 of them for $60 or so, and use them all year. I use an sb910 on both bodies, and recharge after the weekend is over. I never have to worry about them going dead and I usually take over 2200 shots per weekend at roughly 1/8 power. Next year, I'll buy 16 more for the flashes, and put this year's 16 into remote controls, clocks, and other household items... although I'm sure you could get 2-3 years of flash use if you wanted to be frugal.

Used to have a quantum when I was running my flash real hard... now that I've turned the power down, and let the ISO do the work, there's no point in using a quantum, so it just depends on how hard you run your flash as to whether a quantum is helpful.
