220V AC to 3.7V DC Lithium-ion 18650 battery Charger Circuit

220V AC to 3.7V DC Lithium-ion 18650 battery Charger Circuit.
Hello friends, today in this video i have shown how to make a 220v to 3.7 v Transformerless Battery Charging Circuit. Please note the circuit is not isolated from maims so don't touch any naked wire in this circuit when the circuit is plugged in.
Parts list:-
105j / 450v pf capacitor
1M resistor
1N 4007 diode
470uf / (16-25v) capacitor
5mm green LED
330Ohm resistor

This circuit not safe for battery and you because this circuit Fully covered with 220v ac. higher risk to electric shock. This circuit good for lead acid batterys not for lithium ion battery. Don't touch the battery because fully covered with 220v ac one side. to be careful Please don't remove my comments. This comment only for viewers because viewers trying this circuit on there home soo not safe for viewers.
