The best option is to use multiple flashes and have each have to put out less power. A second flash would help a lot but it becomes bulky to lug around. If you are going to be in the same area set one on a tripod in bounce mode and have the other on camera ...
In theory the PTTL will handle exposure from two flashes...
I don't want to get into moving multiple flashes. Thanks!

Originally posted by mcgregni Have you also considered trying better batteries? I think the latest rechargeable types can offer better speeds and may well give you good enough recycling, without the extra bulk to carry and overheating risks of a power pack.
It's been at least 5 years since I've looked into theses. The last time I checked eneloops were recommended, do you have any recommendations?

Originally posted by Rondec My wife bought this:
Flash Battery Pack replaces Pentax TR Power Pack III. - JJC external battery pack and it probably shortened recharge time by 50 percent. It takes AA batteries, while the Pentax external battery pack takes D batteries (I think). I'm not sure where you can buy it though now. It was a lot cheaper than the Pentax battery pack (which we own one of too).
It looks like the link you provided is the same kit as my second option
FB-4
That's only $40. Can you tell me how it compares to the Pentax and whether it actually reduces recycle time by 50%?
My understanding is these might just prolong battery life, only specific models which I think had higher voltage or some other parameter are the only ones that reduces recycle time. I remember many saying 5 years ago the Pentax one just increased battery life.[COLOR="Silver"]
