I have unprotected ones because I own a multimeter and ripped them out of other devices. Works fine for me.>>1437830
Of course the 12,000mAh ChingChongXNite brand cells are fake. I have tons of 1500mAh Samsung cells laying around for various projects. And then those 3350mAh 20650 cells that fit great in those TacticoolLites. The 20650 cells were some other brand but looked em up online and they had tested well, but also 3350mAh isn’t absurd for those cells like the Yuingshu cells thay were $1.25ea from Amazon and say 9000mAh.
It’s amazing reading the reviews on Amazon for all those chink cells. Like 70% of people are idiots who write “These cells work great! Brighter than my old C-Cell flashlight!” and then there’s 20% of reviews saying “That 9000mAh isn’t true” and then the last 10% say “I tested the 6 cells they sent. 3 of them were 1200mAh-1400mAh, one was 800mAh, the 5th was 600mAh, and the last cell was completely dead”
And all of those chink cells have only been listed for a few weeks before they get shut down for their retarded claims, you can’t really find any of the 6000mAh 18650 cells that have been for sale for more than 6mos on Amazon.
