What brand are these 18650 Cells? Are they Samsung? Sony? LG? or some unknown re-wrap?

Hi Tony,

The datasheet says that the cell was manufactured by General Electronics Technology Co., Ltd, which is a Chinese company specializing in the research, development, manufacturing, and sales of polymer lithium-ion batteries and related products. GET is a legitimate manufacturer, so their unbranded batteries are likely just as good as some branded options, like Samsung or Sony cells. Hope this helps.



They aren’t protected though, right? i.e. overcharge, undercharge etc.

Hi Ian,

These batteries don’t have built in protection. Many chargers for them do though, for example
