R1C1 Kit

Stephen, you can always try an 82 - 72mm step down ring. One will set you back $11.06 here at Camerafilters.com. I have no relationship to them, except that I've been a customer in the past. You may have to check for vignetting.

Sorry, I don't know the answer to your battery question.

The biggest size is actually a 77mm, so you might look at a 82-77mm step down ring. I have no idea whether it will vignette.

Another option would be to bypass the ring adapter all together, and just rig up something that holds the SB-R200's in position.

As to the batteries - play it safe, and use the lithium batteries for now, since you don't really know how long they will last in the SB-R200's. If they do prove to be battery power hogs, then start looking at other options.

Hi,

I have the R1C1 kit. I find the battery (the CR 123a) powers each unit for quite a good number of exposures. I was pleasantly surprised. I would estimate that I get about 750-1000 flashes out of 1 CR 123a, and this battery will power the SU-800 commander a bit longer than the individual flash heads.

I looked at the rechargeables too...However, my mental calculations came up with this: but after buying a recharging unit (at least $30), and paying for the rechargeable batteries, you could buy many, many disposable CR123a's. And when I looked, the charger would only charge one battery at a time...so as much as it goes against my environmental-recycle leanings, I purchased a load of disposable CR123a's from this storefront that can be found at www.pricegrabber.com:

I think he charges $1.54 for each battery (generic; but they work fine) plus shipping. I purchased about 60 back in April. He charged me about $7 to ship that amount of batteries. Right now he has 18 in stock. I suggest purchasing all of them, and working out a set charge for shipping.

Hope this helps,

I use the UltraLast Rechargeable Li-Ion. Perhaps the "UltraLast" could be a register product name in China ?

3 Volts, ULCR123R battery made in China. They are rechargeable, and are rated 3 Volts, and not 3.6 like the batteries you have in mind.

I read the Nikon manual, and it does not say anything what battery not to use. It says use CR123A (3V) only, on page 125.

The battery I use is also CR123R (3V), when letter R stands for rechargeable. It works for me just fine.

I got 2 batteries with the Li-Ion Charger that charges 2 batteries and supplies 360 MilliAmps at 3.6 VDC. The higher charging voltage is always required to charge any battery.

The charger has RED color LED when charging, and it changes color to GREEN when the charger is completed. The charger was made in China.

Name of the maker of the charger or the battery is unknown. Since it was sold at Fry's Electronics, I did not hesitate any further.

Some CR123R batteries are 4 volts or even a little higher. If you use these, the SB-R200's will shut down to protect itself. Don;t know what the long term effect is.

At 3.6 volts, as the previous poster mentioned, it might be fine, but who knows what the long term effect is. The units require 3V and IMO your best bet is to use a battery that outpus 3V, nothing more, nothing less. There are many websites that sell CR123A at $1 each, when you buy in quantity.

IMO, the high voltage risk does not offset whatever cost savings there may be in getting CR123R's. You spent over $600 on your kit; are you really going to try to save a buck or two per month ???

I bought this kit for my R1 set from batteryjunction.com:

These perform well in the R200 flash heads--I've been using them for five months without any problems. The charger and four batteries cost $32 shipped and I received them in three days after placing the order.

Danny, But see the specs in your link: "Peak voltage of 3.0V Li-Ion will be 3.60V after fully charged" Are your SB-R200 units still going on well ?
