When to recharge, at which percentage.

Hello, I am starting out and just have one flashlight. I bought three Liitokala Lii-35A for it /Convoy C8 with Cree XHP50.3 Hi R9050, 6V 4A 12-group boost driver.
Now, when the flashlight is hot, and when the battery starts charging off, the light at 100% ramps down in steps, and switches off for a brief moment, to repeat again the process.
Before I had a dirty cheap aliexpress charger that I got before starting out with a flashlight, and when the light wasn’t sensibly hot and it was ramping down, I was putting the battery on charge.
I now bought a Liitokala Lii-PD2 battery charger, and here I can see the percentage of charge as soon as I insert a cell.
I don’t use 100% much, but sometimes I do, and having the ramping down is a bit annoying. Also, it seems to me that after a while from five different light intensities, it goes down to four.
Tonight it happened, I put the battery on charge on the new charger and got 68%, a percentage at which I normally wouldn’t charge anything just yet.
Would repeated charges at a medium-high level shorten the life of the cells?
If so, should I just use more a light that is in cripple mode from time to time?

Thanks

Hypothetically the science suggests keeping the cell between 20% and 80%.

Realistically, you’ll have reduced runtime at the benefit of some more (theoretical) years longevity …

Some guys like this concept, most of us don’t worry too much and just charge when we get the chance, use the light as needed, top up when required…

On full output, this is 24W, your cell is theoretically rated for 10A (36ish Watts). If that’s an overly generous rating, or the contacts of the flashlight are dirty, the light will quickly think the voltage is dropping and alert you.

Lastly, it’s not clear from your post (translator errors?) whether it’s a battery issue or the light is overheating.

Sorry, no, not translator errors, I simply forgot to mention it :grinning_face_with_smiling_eyes:
For example, tonight I was doing some job for 15 minutes or so in the lowest setting, 0.1%, then other 5-10 minutes at 50%, and when I used the 100% mode it started ramping down and blinking. But it wasn’t certainly hot!
Actually, at 100% it just gets warm, but not hot, it doesn’t go into overheat protection.

Coming back to the post question

Me too, but I am honestly using the light because it’s cool, not because I need it so desperately. I could use it a bit more, nothing really would change, just some feeling of annoyance :grinning_face_with_smiling_eyes: hence the question.
For now I solved it putting it at 50% standing, with my wife’s Citizen Ecodrive with the capacitor shot resting on the lens, at least the watch will move a bit, and I will then charge the battery at a lower percentage :grinning_face_with_smiling_eyes:

Thanks!
