Itās a mechanical switch. Reverse clicky. I am not sure about amperage but itās very large, much larger than most other switches. Here it is on the right, next to a Convoy 18650 switch and a Convoy 21700 switch.
Here is is next to an L7 switch.
The spring shouldnāt be a problem either. Check out this bypass design. Very clever.
I see. Thank you for the info. I will contact Neal and ask about this. Perhaps he will be willing to send me a replacement driver if mine is indeed faulty.
Where you have see low voltage protection?
Always only write a third function, Low voltage warn.
Not only on this light, in all Nightwatch light, Only low voltage warn.
1 reverse polarity
2 control temp
3 Low voltage warn
All UI and function or copy and paste light after light
You need to charge those at very low current, like 100 mA to safely being them back. I have done this with success even on super-dead 18650 from laptop pulls at like 0.8 volts. They do take a capacity hit and discharge current will not be as good so those p42s might be relegated to under 10 amps. Youāll know if it is successful if you let the fully charged cells sit for a couple days. If the voltage drops rapidly like 1 volt per day, then theyāre junk. You can try another cycle of very low current, but it might fail again. You can also do a discharge test at 1 A. If the voltage drops rapidly, theyāre permanently damaged.
Ok, Iāve donāt reply to @robocop at page 4
But for me I donāt trust Neal info from Nightwatch, the pair is explosive for unvolontary mistake
Iāve change alu bezel for steel bezel without hesitation, for me no alu bezel for this light.
Problem with Li-ion discharged below roughly 2.5 V is that you donāt know if dendrites started to form. You might ārecoverā the battery just fine, but in a few days or weeks it might just catch fire by itself. Internal resistance, self discharge, voltage curve ā nothing will indicate that the battery is damaged internally. Iād say it is just too risky to try to save a few bucks. Take your loss and dispose them.
Since the batteries I bought for this light are potentially toast, Iām using another set of P42Aās now and with these Iām getting up to 22,000lm @turn-on. A 10% increase. Neat.
Ho my god, Iāve try it at my windows
Il like the beam, massive and powerfull hotspot and wide spill , think similar to astrolux MF01S, around same size but less bright, more spill bright, I like.
The building a 200 meter full illuminated.
Wow if the cooling fine do job , damn, medium mode seem be good too.
Iād really like to test it tonight :weary:

Great word, just ask for 2 new cell and no new driver. In memory of the two P42A low volted
