I have been fine with nitecore for years. But this issue has popped outta nowhere and just on basic principle that a light should never “break” on anyone in this way has left me incredibly annoyed as it’s absolutely a safety issue. I trust my lights i buy specifically for their ability to regulate and fully shut down once the battery is low. That flies out the window if i come home to a failed flashlight *that was only on brightness level 2* in order to fail aka not a hot mode. (We have a power outage right now. I like to tail stand my lithium and smart AA lights throughout the house and up till now this seemed like a great light for that.)
I am sad because the nitecores ability to blink out voltage readings and power down when voltage went below 2.8v and it’s thermal regulation meant (i thought) that i could set the light for my kids and leave home and come back to at most a few of my lights being off if the battery dies while im out. But this is unacceptable. I am sure nitecore haters would be vindicated to hear this and i for once will let you have it.
Nitecore.. WTF
hequfe
You are right it shouldn’t do that
UnfortunateWah
It has negative and positive contacts in the front of the cell like Olights do, ie it’s a proprietary cell.
Much like many Olights, it’s therefore possible to run the light with the tailcap removed.
In terms of it *always* staying on, yeah that’s a problem with the switch or driver.
