Building a PHR-803T Laser Need Advice!

I currently have on order a
PHR-803T laser diode
Aixiz housing w/ glass lens
Rckstr Driver
My question is what host flashlight should I use in order to obtain the 9v of input into the driver to power the 5.5v required by the diode?
Thanks
Andrew

A search in the, "B/S/T", or ," Pro Shop", thread will quickly answer your question.

You could always introduce yourself in the, "Welcome", section first...

I looked there man didnt answer my question what so ever.....
What is everyone using for batteries/or voltage into the driver to power there phr-803t diodes?

How does the rckstr driver handle a 9v input?

you could use a MXDL flashlight host (DX item # 3405) and go with 3 of the 10440 batteries to get like 10-12V. search for JayRob's kit better yet and just buy everything together, he makes great heat sinks.

thanks,

Great batteries to use are lithium ion, as already mentioned by Kendall here,
10440 Li-ions are exact size of AAA, but instead of 1.5 V each, they carry 3.7V each, 4.2V when fully charged.

14500 is size of AA.

So you can get ordinary hosts and use lithium ion batteries to get needed voltage when running linear regulators like RCKSTR driver or homemade LM317/350/1117, or whatever you use.

You can get batteries cheap at DX:
10440 :
DealExtreme: $4.23 Ultra Fire 10440 3.6V 500mAh 2Pack

14500 unprotected:
DealExtreme: $3.99 TrustFire 14500 3.7V 900mAh Rechargeable Lithium Batteries (2-Pack)

14500 protected:
DealExtreme: $4.73 TrustFire Protected 14500 3.7V 900mAh Lithium Batteries (2-Pack Blue)

There are also protected 10440 but I have not tried them out myself, but AFAIK they will not fit in some 3xAAA holders.

Also, difference in protected and unprotected:
Protected batteries have a small regulation circuit on round thin PCB on their negative end, the circuit monitors the batteries voltage and when voltage reaches critical discharge limit, which is 2.75 for li-ion chemistry batteries , it will shut off the battery to prevent damage.

Also can protect against short circuit and overcharge but that is not as neccesary.

EDIT - Oh I'm sorry I forgot the chargers:
http://www.dealextreme.com/details.dx/sku.4151 this one has sliding contacts and will charge almsot all batteries between 10440 and 18650, however it's sold out so I think this:

Is exactly the same but black color.

THANKS!!!! Yeah I will Just order these. I was going to hand file out a host that fit 2 AA in order to make it fit cr123 batts. Thanks again for the great advice

No problem, for two AA host , pick unprotected batteries, protected ones are ~2mm longer and when two are put, you have 4 mm of extra and you most usually won't be able to thread the tailcap, so get unprotected to fit it right.

2 standard cr123 will not work. they are only 3v each. you need at least 7.2 volts just to lase. not taking into acount voltage drop at power up. so you will need a minimum of 2 3.7v batts fully charged. 3 is ideal for maximum runtime.

all stated info of for the rkcstr driver.
