Wellp, let’s put it this way… even a car’s big honkin’ battery can go dead if you let the car sit unattended a month or two, yet no one complains about that as a defect.
Anyone who’d expect a light to still have juice left after being abandoned in a drawer or closet for months should just get a cheepcheepcheep plastic D-cell light from CVS. Don’t even waste a Maglite, ’cause it’s cheaper to toss the cheap light once the alkaleaks do their thing.
I seem to remember that LVP only works when the light is in use, not when sitting in the off state. TK is the person to ask. You could use a protected cell to be sure.
Sorry, I can’t remember if I tested that. And I let my SC31 Pro go home with a friend, so I can’t test it now. Hopefully someone else can chime in. I know some of the newer Sofirn/Wurkkos lights can indeed be charged with USB-C to USB-C.
The SC31 Pro flashlights that I have will not charge using a normal USB-C to USB-C cable from any of the USB-C ports on my chargers.
For my chargers with USB-C ports that would not charge the SC31 Pro with a USB-C to USB-C cable, I use the following USB-C to USB-A adapter with the adapter plugged into the USB-C port of the charger and a cable with USB-A to USB-C connectors plugged into the adapter and the SC31 Pro. The adapter is uni-direction and the adapter's USB-C connector must be plugged into the USB-C port supplying the charge to work correctly.
Yes, you could absolutely use a high-drain cell. Sorry, I don’t have any tests right now with those. I doubt you’ll see a ton of difference because Anduril’s thermal throttling will likely kick in before you have to worry much about voltage sag. Just a thought, reality could be different.
According to the review, the Sofirn-branded cell is a button top battery. Does anyone know, if flat top 18650s will work as well in the SC31 Pro without any problems?
Thanks a lot in advance!
I was looking at them too. Thanks for the help. Do you know whether the USB charging of the SC31 pro is too high a current for 18350 cells? I saw 1.87 amp while charging a 18650. I was wondering if the top current self adjusts to a lower current when an 18350 battery is being charged?
I just remembered I have a fully charged 16340 to test in the shorty tube. It did charge at a lower rate of .90 amp. Max charge current is about .5 amp for a 16340 so not good . It did drop steadily though.
Good tip. The second time I read that from you and I completely forgot. What rate do you see charging an 18350 from a 2 amp charger or haven’t you looked? It would be nice to be able to charge from the car or out and about if I could. I’m on the fence about buying 18350s. Another thing, my shorty tube that came with my SP 40 headlamp screws into the head either end but the tail cap only screws on half way on one end though it will screw on either end of the 18650 tube. Weird .
