Are the lithium batteries sold with lights safe/UV light discussion

I do see a few has high internal resistance on my vapcell s4+ so obviously QC could be an issue. Other Chinese branded cells like LISHEN have the similar issue. I remember seeing a report saying that the QC failure rate of these Chinese cells is much higher comparing with major brands.

Resistance is never accurate on a charger though, you’d need something like this

I found the Sofirn 21700 5000mAh (Lishen LR2170SD) to be excellent, I reviewed it here I ended up purchasing 100pcs of these from 18650batterystore.

Can’t really expect China cells to match the same QC when they’re priced so much cheaper. They’re decent for what they are, I just wish Sofirn gave the option to bundle Samsung, Panasonic etc.
