I have a question. I have acquired the R1C1 and 4 SB-R200's, this comes with a problem. CR123A batteries are expensive. I did a web search and found a site that sells rechargable CR123A batteries. My question is are these rechargable batteries a worthwhile investment? I have spent too much money on gear to have it ruined by being cheap on batteries. The site is http://www.cr123batteries.com/?gclid=CKTcrL-7krMCFS-RPAodkFoAUw.
Yes, for some reason CR123's seem to pose a real problem for rechargeable battery manufacturers. Perhaps the volume just isn't there for them to bother.
I've tried a few, and have had decent luck with a set of 4 Tynergy RCR123A rechargeables in my R1C1 kit. I would not rank them as good as an Eneloop (who doesn't make a CR123) but they seem to hold a charge decently.
I have been using the Tenergy RCR123A Li-ion rechargable batteries in my SU-800, SB-R200's, and my Sekonic L-758DR for the last few years and they have worked quite well. I purchased them at Battery Junction . The current batteries and charger in the link appear to be slightly different from the ones I purchased a few years ago but it is more than likely just cosmetic. Good Luck and Enjoy your Nikons!
All reports here, have indicated that they can be used successfully. I have read where the rechargeables have a higher voltage and can damage some things like Surefire flash lights. I don't know how to determine what can and cannot be damaged. Evidently Sekonic meters and Nikon flashes do OK.

I use RCR123A from Delkin Devices and have had no mishaps. I use them in my (4) SB-R200, SU800, and My Sekonic L-358 light meter. Whichever brand of rechargeable batteries you use, it has to be cheaper over time than the throw aways. As pointed out by Mick, make sure you use the correct voltage battery or you may damage expensive equipment with no recourse for warranty or repair. Thanks Marty for your link to the site that has something that I could not find anywhere else and I had to improvise. That is the little plastic case to store the batteries. Neither Delkin nor other battery sites I perused had these cases. I have been using a hospital glove and placing the batteries in the finger tips of the gloves to keep the ends of the batteries from touching and creating a fire hazard.
You may want to stay with a known manufacturer who uses rechargeble batteries. Surefire makes flash lights for law enforcement which in most cases are rechargeable. If they did not work they would not be bought. I have used the CR123A batteries by them without trouble since I keep one of there high intensity lights in my car.
