3.7V Lithium-ion battery charger with battery full indicator without IC
How to make 3.7 volt Lithiun-ion Battery chager with full charged indicator without IC. By AMKP40 technology. This circuit work perfectly with 5V DC adapters and 3.7v lithium-ion battery. If battery is fully charged with 4.267v than RED LED turns off that means battery is fully charged. If you want fast charge your battery, you just change the resistor behind this diode. Also you can adjust which voltage you want to show battery is fully charged, just rotating the 1K veriable resistor. This circuit Diagram is personal of AMKP40 technology [YouTube Channel].

Deletebattery over charge hoga..
ReplyDeleteBattery over charge nehin hoga agar aap ek braded 5v AC to DC adapter use kare tao.

Agar battery Samsung Ya koi Archhi brand ki hogi to uske andar hi over charge/discharge protection circuit aa jayega..
Deletedon't worry then.
Sir , is circut se battry bhi charge hoga kya
ReplyDeletehaa bhai.. Diode ki vajah se battery charger bhi hoga power on condition main aur power chali jayegi to leds on ho jayegi..
Deletei think 1200mh ki battery 24 hours ka backup degi..
Super idea tank you
