260W IR Laser pump handheld?

Yes, I will be very careful. I decided on step-up drivers, as the accumulator that I will make again will be 24V from 18 pcs 18650 batteries. I also ordered the one from 1200W, but I am leaning towards the one from 28V /20 A. I don't know if these 2A in addition will not damage the laser. I see that the specifications give it a maximum of 19.8V and 18A. That is, at 28V per driver, it cannot take these 20A current.

I just found this on AliExpress:
BGN19.34 | 1200W 20A DC Converter Boost Step-up Power Supply Module IN 8-60V OUT 12-83V With Heat Sink 1200 W 12V to 24V 48V 1200W 20A DC

Also an option is to use two drivers connected in parallel. Because I have one of those 600W each that I use for NUBM37 and NUBM38.

I am currently experimenting with a PS like the one you show on the left. I need 15 v @ 15 A for my MAX 130. I've read that running
two of these in parallel is not recommended. Mike

I got the lenses. Everything is perfect. I still haven't adapted them to my lasers because I don't have time. For the large one, an adapter will need to be made. I plan to put it on my 500W pump.

Where did you find the lenses? Which one works ? Mike
