Which Thrunite flashlight has it?
Lou, any of the multi cell lights i have had from thrunite have been issue free from parasitic drain(everything else issue free wise for that matter!). Hopefully with this type of propitiatory pack, a simple turn of the tail cap will lock it out anyway.
I will not purchase a Proprietary battery pack flashlight; in a few years of use, a bad internal charging unit and or bad proprietary battery and the light is an expensive paper weight.Great features but.
Proprietary battery pack, NO THANKS!!!!
Why didn't they go with a single XHP70 and one reflector?
