If the battery size is the same, can I put any battery type in my laser or flashlight?
For example, if I have many types of 18350 batteries, Li-ion(ICR), IMR, INR. IFR(LFP), Li-Polymer Can I put any of them in the laser? If all sizes are 18350.
I'm looking for a laser with an infrared filter. But I want a product that's not too expensive. Pls Which of the lasers on this list has an ir filter?
Or you can recommend another product.
