See the thing is 18650 batteries needed to power a powerbank is different then a 18650 battery used to power a EV or power tool.
A normal flashlight with a single XML emitter can be used with any cheap 18650 battery, but not the high power multiple emitter ones which can pull around 8amps.
The flashlights I give my parents all have protected batteries custom made by me.
The flashlights that I personally use all have unprotected batteries.
The batteries you get in India are 90% chinese no name fakes, rebadged to a well known names.
I got my batteries from reputed sellers years back when faking batteries was low.
All my batteries are of Sony/murata VTC6 or the sanyo/Panasonic GA series.
21700 are samsung 40t which I got from a power tool battery.
A fake battery on other hand can explode when discharged at the same amp draw. There are fake VTC6 and what not.
When you see fires in EV like scooters, mostly are due to fake batteries. Even ather during the initial days of their launch had encountered fake batteries in the supply chain luckily it was caught before being put on a production vehicle. Since at that time there low import numbers meant they could not place a order directly from the manufacturer. Now that the scale of production is higher they can order from the manufacture itself. Typically order value costing below 1lakh dollars is not entertained.
