Like I said, I don't plan on using it much. My alternative is that I use the AA or AAA battery holder inside the mini flashlight that it comes with instead. The battery carriage will most likely hold 3-4 batteries I'm expecting. Are there any other batteries I could use for my laser if I choose to go that route?

Using the Rkcstr, you will need the 3.7V lithiums to power it. You can fill the empty slots in the battery carriage with some sort of "dummy." If you change over to the microflex (flexdrive), you can use standard AA or AAA batteries.

Sorry to throw a wrench in the gears, but, since when do we recommend 2 X 3.7 batteries for a Rkcstr configuration? Igor, and a pile of you guys drilled in my head that a minimum of 9v is needed to run a Blu-Ray efficiently. Even fully charged 2 X 3.7v batteries are only 8.4v, and it will drop fast after less than a minute of use. I've seen people selling Blu-Rays left and right with this configuration. I know using 3 will be 12.6, but its less than a minute before they drop to under 12v. What changed? You'd be lucky to get 20 minutes out of 2 X 10440 batteries, and the laser will weaken almost immediately with these higher powered diodes. If the 12.6 voltage is an issue, a simple $0.80 silicon diode would resolve that. Am I missing something, or is this just a ploy to sell cheaper Blu-Ray lasers without a Flex? I dont get why else this configuration is being accepted over the traditional right way of doing it. [/Rant]
Sorry, been meaning to vent this, and this seemed the right time.

I think that somebody misunderstood somebody. Don't know who. Don't know why. Don't care how.
I don't recommend using 2 @ 10440's for a 6X, but it can be done if one is willing to accept the shorter time between charges.

It was not pointed at you Dave. Just a general comment on some of the builder here. You hardly ever hear the proper info anymore. People are building, and selling lasers like this, and when people are asking advice, they get that 2 is OK. 2 is not OK. Yeah it will work, but its not designed that way. I dont understand why people are selling these things, and no one says a word.

ill do a test with mine.. as long as it doesnt over heat i will tape my momentary down and time how long it lasts and post in a new thread. I'm gonna charge my batts right now.. my set up is a phr with 2 10440's in a wicked core host set at 90ma.

Facts is facts. But if want to do it you'll need a LPM. You'll also need 3 batteries to compare. This has all been done before.
It will work, but you wont get full power, and what power you do get wont last. You said it yourself it loses power quickly.

It is true. We get lots of people giving advice that should not be giving advice. I just dealt with a NooB telling a NooerB that 800mW was a good power to run his 12X at because he saw that a couple of others were running them at that output.

Start preaching that 2 batteries are not correct, like we used to. But I'm sure that would piss people off.

But they are correct for PHR and lower. Many 100's of lasers have probably been built with that configuration. And they are acceptable for 6X *IF* one accepts the limited run time.

Not all Li-Ion batteries will drop from 4.2V to 3.8V in under a minute. If you are using 2 18650's, you will have significantly longer regulated runtime than if you were using 2 10440's. With a boost driver, you get regulation for the whole time, but since you are boosting the voltage, you are pulling more current from the cell at 3.6V than you are sending to the LD at 5V. At some point, overdischarging the Li-Ion cell may become an issue.
"Check out my BR lazor, it burnz at 900mW!"
*Cue single 10440 cell venting with flame*
So, under certain circumstances, I could see using only 2 Li-Ions as feasible. But having control over the entire build, you shouldn't have to make that sort of concession.

That's for a boost drive, not a linear driver.

No one has ever said that to me. Igor wrote me a huge paragraph on why 2 were not enough for my PHR build. I've read countless threads on these builds by builders and they all said the working voltage for a PHR and Rkcstr build is always been 9-12v, and not 7.4-8.4v, let alone using it for a 6X. I dont like this misinformation, or lack of information, being posted for the sake of selling lasers. This forum was not suppose to be about that. I cant believe that you are sitting here and telling me its "correct", and "what can you do about it".
