Curious if anyone has experience or opinions on 18650 batteries.
Have you had bad experiences from the cheap ali-express batteries? Is it worth paying the extra for Samsung?
Purpose is to rebuild Eufy S330 camera battery pack (unable to charge)

Thanks, very informative
I have only ever bought the cheapo ones from AE or maybe Temu - I can't recall. They are unbranded.
Been using them in a charging pack for about a year and they are working fine up to now, but I have no means of comparing.
Wouldn't go near them known history of being either fake capacity or dangerous.
Samsung/LG is what i used to rebuild my Xiaomi AirPump which still works fine today.
Would recommend looking at cell tests from Mooch to make a decision. Here's his Facebook page

Stay away from unknown brands. Stick to known brands like Samsung, LG or Molicel.
You probably don't need to worry about over discharging in a camera but those no named lithum-ion cells have very poor quality control.
Highly recommend watching https://www.youtube.com/watch?v=-Y23nfAOiXQ and educating yourself on lithium-ion safety.
