Just be wary of them as they are likely unprotected cells.
Batteries made for flashlights will have a protection circuit board on it to protect against over & under voltage and sometimes overheating.
Unprotected batteries do not have a circuit board on them and are usually protected by the device that they are installed into.
You can use them BUT you have to be incredibly careful with them as if things go wrong you will be holding what has essentially become a small pipe bomb.
This is just not true. The circuitry is in the flashlight, not the battery.
There is usually basic over discharge protection in the flashlight circuitry and over charge protection for lights with on light charging.
This usually works in conjunction with the protection circuit on the batteries.
18650 batteries (and other sizes) have become more wide spread because of the increased safety of protected batteries.
The batteries OP wants to use are unprotected cells who's manufacturer is unknown, actual capacity is questionable and how they have been handled is unknown.
