+1 for that!Dave's in charge of organizing the 445nm subforum.
I wanted to state that, according to the maker, AW's rechargable LiMN RCR123 cells (not LiCo) are capable of ~4.4A draw. These are the IMR17340's.
Most of you are using LiCo cells, the best of which are really only recommended to discharge at around 1.5A. (safe guess for 16340's is approx 2C)
Let us know how they go.Well, I bought two of the LiMN CR123's and one 18650 as well, I hope these are up to the task, Im pumping alot of current nowadays, 18650 build kit is going to run at 1.1A and my pocket mini CR123 is at 700mA.....
I wouldn't be too sure that it was the battery that caused it to pulse.. I've noticed on my groove 2 driver that it heats up quickly and when it does, it starts to pulse as the drivers internal overheating protection kicks in to cool the driver down. it will come back on when it drops below max heat and off again when it heats back up. Try heatsinking that chip and you may find that you'll be able to easily handle 800mw.I was able to hit 800mW but that was only for a brief moment before the driver began to pulse the laser due to the battery.
Both are runnning very nicely! The 1.1A flex is doing better than I thought, using the LiMN 18650. It has a nice and steady output but I havent ran it for more than 40sec straight due to excessive heat. I havent tried this build with a standard batt but when I had the diode in my labby heatsink at 1.3A, a standard 18650 was running it fine with 2 minute duty cycles.Let us know how they go.
I've got my boostdrive set to feed my diode 650mA but if this battery can supply an amp of current at at least 3.5v I think I'll turn it up. I think my Ehgemus host should have good enough heatsinking to run the diode up to an amp or so.
