2 Questions about batteries in laser

Be carefull with the duty cycle.
I believe JLaser is over rating it. You have a SS host and a small 12 module, even if it a copper module he's rating it at 30 seconds on but a good 5 minutes off.
I wouldn't do more than 20 seconds on.

He has a IR laser in the same host at 500mw and mentions a 100% cycle. No way on that cycle.
Same host with a 1.6W blue aand he's got it at 1 minute on

I have another laser from him using the same host. It's the 700mw 520nm. 1 minute on, 5 minutes off, and that's 1/5th the wattage of the one I was considering. I try not to do more than 30 seconds on, just to be safe, but sometimes I lose track of how long it's been. I try to stop if the laser head feels warm.

Green direct diode lasers get very hot. I would guess a 700mW 520nm compares to a 2.5 to 3W blue.
Can you see what the 12mm module is made from? That makes a big difference.

Like you mentioned keep the run time at 30 seconds max. JLasers is good at keeping the down time at 5 minutes

No, and I wouldn't know how to find out. If I start taking things apart, I'd probably wreck it since I'm not familiar with laser building.
But here is the diode (I'm assuming that's what you're referring to) that he sells on his site that is probably the same as he built my laser with: https://jlasers.org/products/diode-gh05c01a9g-700mw-520nm
I don't know if you can find the answer by looking at this.
