So i got this flashlight-it has built in lithium 18650. But i looked the PCB, i think it's way too simple. I only see resistors, and only has 1 super small IC.
Does this even work for guarding and protecting lithium 18650 like BMS? I compared it with TP4056, tp has lots of IC (DW IC protect, and the tp itself)
Does it :
-protect overdischarge?
-protect overcharge?
It seems like a dumb charger look a like though, no CC CV thing i guess? but what your opinion? im not from electronics background..
The IC :
The entire circuit
