I was thinking about buying a wurkkos fc11 as my first flashlight but it said they recommend untwisting it in a review to avoid making a connection so it doesn’t discharge while not in use. Do I need to worry about that with all flashlights? I was planning on keeping it in my backpack so I have it whenever.
To add to this, if you are going to store your Li-ion batteries for any period of time then you should charge them to 3.7v instead of a full charge. This will extend the life of the battery
Worth mentioning that some chargers offer a storage option, charging to exactly 3.7V.
On a charger that doesnt have this, it can be difficult to monitor it closely enough to get that exact voltage.
Good tip, but the OP should be aware that when at 3.7V they have only ~50% charge in them, so remember to also pack a spare or two (at the same voltage) to have the same total runtime.
Should be closer to 60% but still, it’s not in a long term ready state. Long stored batteries should be recharged before use.
