Hey guys, I have a question. Does anyone know what the max mW output would be if I put a RCKSTR V3 flexdrive on a 9V battery?

rkcstr doesn't make the flexdrive, and the mW out depends on your diode and how properly heatsinked it is. If you're using a v3 flexdrive, I'm pretty sure 9v will kill it.

What Prototype said is true. In addition, the standard 9V battery creates insufficient current to run a diode very well or for very long even with the Rkcstr. Opt for another power source if you can (or be willing to stay with a very low output.

Sorry I ment a flexdrive, and it is for a 6x blue-ray and I bench made the heatsink so that's no problem it is big enough!!

best to go with an 18650 li-ion battery when using the flexdrive IMO.

I just realized that part of the problem is that this is a V3. The 5.5V input voltage limit is the same. However, I do not have an old manual available for the V3. Send drlava a PM to find the output limits on the V3.
Unless someone else still has it around.

I'm confused. I'm new to building, and have all the materials now, they've arrived at my house. I have:
a phr in an aixiz housing
a rkcstr microdrive, v3. I used a test load, and set it to 115mA
a 9volt battery
and I'm hosting it in a project box, until I find a real host.(or can afford a kit)
So, are you saying the 9v will fry my driver?

There seems to be some confusion. There are two main pre-fab drivers that we use. One is rkcstr's microdrive,
and one is Dr. Lava's FlexDrive
Which one do you have?
Since you already set the current with a test load, I'm guessing rkcstr, correct? The Flexdrive dies @ > 5.5v.
If you have a rckster, then a 9 volt battery is safe, but less than ideal.
(I know the images are hotlinked from a couple of members here. If that's a problem, PM me and I will correct it.)

In post #4 he corrects that he is using a flexdrive NOT a Rkcstr. He should edit his OP

The V3 Flexdrive has an input voltage of 2.5 to 5.5 V Dc and up to 6.2 V with a diode in series.
Attached is the data sheet.

Sorry for all the questions, but I really want this laser to last. So, if I power it with a 9v battery, will I lose potential power out of the diode? I'm keeping it on a very short duty cycle, as well.

If you are actually reading this, you will see the the OP is using a flexdrive, NOT a Rkcstr. The Rkcstr will take up to 12V. The only problem with your build is that the standard 9V battery sucks as a power source.

Sorryif I'm asking too many questions, but why? Not arguing with you or anything, I'll definately switch power sources. I'm simply curious as to why the 9v is bad?

the flex drive is a boost driver. it boosts the voltage up. a 9 volt battery is too many volts as stated in the above posts. if you want a reason as to why, then you will have to contact the manufacurer.
