Oksy so I have ordered a bunch of rechargable 16340 and 18650 batteries but I understand that they are not protected cells. I want to make sure that I am using them safely and not running them too far down. Can anyone tell me how to judge when they need to be recharged?
My flashlight will automatically switch to strobe when the cells get low so that works there but how do I tell with a laser?
Thanks
