A couple questions about batteries:
I do not vape or make my own powerwall etc so much of the information on 18650 cells seems conflicting or not relevant.

I have 4 unprotected button-top Samsung 30Q used just for the BLF Q8.
I just purchased these KeepPower IMR button tops to use when the 30Q are charging.
Are they protected? Are they a good/OK choice for the Q8?

I have a few protected cells that came with lights such as Sofirn, Thorfire, Folomov, etc. 2600-2800 mAh. I lend and gift these sort of lights to co-workers and family (adult children) when they show a genuine interest and a willingness to charge a light.
I am running out of those but I have some Panasonic flat tops NCR 18650B 3400mAh that are unprotected. Would you trust a muggle with an unprotected cell and the cheap usb chargers that usually come with a bundle?

I opened two laptop batteries from ones with broken screens and found:
Sanyo UR18650A rated at 2100mAh- I have been using in a Convoy S2+ (6x7135) and they work fine.
Panasonic CGR18650C rated at 2150mAh- I have been using in a Thorfire VG-10S and they do not last as long, or get as bright, but seem OK.
I would like to get a way to discharge/analyze them so I know the resistance and capacity, but for the price i could buy the Convoy L2 I have been eyeing with two 26650 batteries.
I am just using them and assuming they have half the rated capacity which is good enough for my everyday needs with these lower drain lights. I will never use them in series or in a high drain light such as Emisar D4. Any issues?
Stick with the 30Qs for the Q8, as they work very well.
If the light itself has LVP, why not? Nb: some lights just warn of low-voltage, but donāt turn off, so make sure of that first.
Cheap chargers might at worst shorten the life of the cell if it overcharges, but donāt expect it to burst into flames or anything.
Not really. Iām not paranoid about Li-cell safety, just practical, but I still use laptop pulls that are half their rated cap, or less, and never had an issue.
2. Slicing the Xpl2 5000K with a razorblade gives the exact beam pattern of the XPL hi, but it reduces output dramatically (30% or so) the 5000 K shifted to approx 3700 K
Recent update from Windows 10 (Friday June 8th) bricked my laptop keyboard and touch pad driversā¦ now Iām stuck using the touch screen keyboardā¦
Hereās how it went:
10;30 pm while watching shows on Netflix with the kids, the windows update popped and ask for install and restart now or laterā¦ i chose restart laterā¦ finished Netflix, got too tired, went to sleep (closed the folded the screen down)ā¦ woke up to check email at 8am Saturdayā¦ no Windows log-in screenā¦ no cursor on screenā¦ keyboard keys and touchpad all unresponsiveā¦ had to log in with touchscreen keyboard (sucks crazy) and connect an external usb mouseā¦ i checked the hardware drivers and it has issuesā¦ keyboard driver (ps/2 keyboard driver) has a code 10 issue and touch pad pointing device has a code 39 issueā¦
i have a Lenovo Flex 2-15ā¦
tried uninstalling both drivers and rebooting several times to no availā¦ yes i tried rolling back the drivers, tooā¦ holding off on widows restore as a last resortā¦
Anybody have these issues, if so how did you fix?
Naw, the damned thing kept ruining a work laptop, killing wifi completely. Know what a laptop is without wifi? A brick.
Kept rolling back, uninstalling drivers, etc., and that eventually got wifi working again, but slooooooowly. To finally stop its insistent attempts, I found the dir where it starts dumping new files in preparation for mangling the OS beyond recognition, āwindows10upgradeā or some crap like that, created a file with that name, and turned off all attributes, especially admin, to make it untouchable.
For a while Iād get popup boxes citing an āerrorā, as in not being able to create or write-to the dir, and it made me feel good. It eventually stopped trying.
āLightUpTheDarkā If you can get to the ā system Restore ā do that first. If that works, disconnect the internet immediately, find the Windows update and turn it off, reconnect the internet. You need to have a restore point saved when you are done and you need to be prepared in advance for those PITA updates.
I did the restore to a previous point via Lenovoās (or maybe windows 10 safe mode via delete/F2 during startup) and restored to Thursday June 7 restore point and it fixed everythingā¦
After windows reloaded with working hardware keyboard again, created a new restore pointā¦
Or do, as I do, and only use Windows for gaming, and use Lubuntu for everything else, except for Excel too.
Lubuntu, compared to even Windows on an SSD, is crazy fast. It boots in like 2 seconds, and there isnāt any lag in the system, unlike Windows sometimes.
