- Hello! Universal 18650 Battery Charger. LiitoKala Lii M4S. I took apart an old huge battery and tested all 18650 battery cells separately for new projects.
It's very strange, when disassembling the battery, the 18650 cells sometimes smoke when you separate them, although I do not short-circuit them. You have to be careful with them!
Write in the comments how to do them correctly, maybe I did it wrong!
Thanks for watching!

I noticed that when I fully load the 18650 batteries. When I use a 3 amp power supply, the liitokala gets very hot. But when I use a 2 amp power supply, the liitokala does not get very hot. Interesting!
Without measuring IR this is nothing
Yes i know i had to check everything for the video. But I didn't have much time to shoot a video, and I wanted to show only the main thing, how to quickly disassemble and test all 18650 banks. There were a lot of bad ones, they sat at 0 without recovery, so there was no point in shooting a lot. I use such old 18650 banks in my projects and homemade Power Banks.
@Robotics_Robot me too, i mainly buy used battery packs from local scrap company. Sometimes only 2 was bad in pack, but in majority of situations always is 50%50%.
Of 100 in pack 50 are bad ( bad IR or on 0V ) also using it im my DIY. Greets
@@soulbrothers7789 Yes, that's what I meant! It's cool when you make your own inventions. Thank you!
Mine leaves 18650 at 3.6V after testing instead of 4.2. I really don't like that.
It seems to me that it is broken, like it worked a lot. Measure the 18650 battery with a simple tester, after charging it on the LiitoKala. :)
@@Robotics_Robot i bought from other seller and it's working properly now
