3·1 year agoThat photo doesn’t look like a Sofirn LT1S at all.
You mean Li-ion with integrated step-down converter? They usually require their own special “charger”, there’s no universal standard.
For example Sofirn SC32 or Manker U22 III.
Stubby lights are often hard to hold. This design feels surprisingly secure in your hand. The wait really helps a lot.
It will run higher right after turn on for a few minutes. That’s pretty good for a turbo mode. Many flashlights hold their maximum brightness for only a few seconds.
Usually I have my eyes closed during showering (without glasses I wouldn’t see much anyway). So not much light needed.
Thanks for talking me out of it!
I had the Slimblade for five minutes, until I quickly returned it because of the bad buttons and the high ball without a proper wrist rest. Eventually I found the Elecom Huge which was just perfect for my hands. The Deft Pro works also great. Tried various other trackballs including thumb trackballs, but none worked as good as the Huge for me.
Indeed, it’s an Elecom Huge. Also have some other Elecom like the Deft Pro and still thinking about getting a Bitra (although it might be too small, but not much more portable than the Deft Pro).
No, I’m in no trackball group. Just using them everywhere.
It was just released. They have many flashlights for all kinds of purpose. The SC13 is more a small EDC flashlight.
It seems to be available at their AliExpress store: https://www.aliexpress.com/item/1005006374608354.html
Nope, there isn’t.
Just in case someone thought they had a deja-vu: I reposted this because my original post went missing when Feddit had to restore an old backup after a crash.
Unfortunately Feddit crashed and lost this post. So I made a copy via my alt account here: https://lemmy.world/post/10136273
The protection circuit of a cylindrical Li-Ion battery doesn’t report anything. All it can do is to interrupt the circuit if the current gets too high or the voltage too low.
You might mix this up with tool batteries that usually have multiple cells in a series and in parallel, monitored by a battery management system (BMS).
Most quality flashlights have an integrated low voltage protection. The protection PCB will only protect the battery when it’s handled outside of the flashlight, but it will usually reduce the performance and efficiency due to the added resistance.
