Powering an Osram PLP520-B1 Question

[procrastimator]

Ok, so long time lurker first time poster. I've bought high powered green lasers online before, and I have safety goggles. Now, I'm planning my first build and I'm a little confused as to what type batteries to use, and how many of them. I'm planning on ordering an Osram PLP520-B1 in a copper module with a 550mah driver from DTR and put that in an S4 host with extended copper heatsink from Survival Lasers.

From what I've read over in DTR's thread about the PLP520-B1 I can't use a single 18560 battery to power it, using an extension and 2 18650's would fry the driver, but using 3 might work. So, can I just use 2 extenders and 3 18650's? I also saw reference to some new batteries I'm not really familiar with; AW IMR 14500's and 16340's. Will these fit in an S4 host? How many would I need?

I don't understand why I can't use 18650's? The output voltage for one is 3.7V, which is right in the 3-5V input requirement of the Diode/Driver assembly. I get that I couldn't run 2 in series, but couldn't I just mod an extension tube so that I'm running the batteries in parallel? Thanks in advance for any help you guys can provide

Let me know where it says you can not use a single Li-ion like an 18650, 18350, 16340, ect... and I will get the info corrected as that is not right. The unit will run on a single Li-ion. Two li-ions in series would be too much but a single is the ideal power source.:beer:

with a 550mah driver from DTR

you mean a 550mA driver where it is the current it is set to and 550mAh would be a measure of capacity like what is stated on a battery.

Thanks DTR! Upon re-reading your thread on the PLP520-B1 I realized that I simply misread your post about batteries. For some reason, I combined IsaacT's post about this diode not liking single liion cell with a boost driver with your earlier post about drivers and batteries in my head. So my bad, lol.

Also, yes, I meant with the 550mA driver; for some reason I always want to measure capacity as ma and current as mAh. It's like electrical dyslexia, lol.
