Low battery cut-off circuit for 12v battery. Over discharge protection circuit for 12v battery.

 Low battery cut-off circuit for 12v battery. Over discharge protection circuit for 12v battery.  Cut-Off Voltage 9.80v or less and Recovery Voltage is 10.00v or higher.




DISADVANTAGES:- 

        [1] In this circuit's Relay consume power while circuit is on mode, but not consume power while circuit is off mode.

         [2] Practically this circuit creates some problems when you use this circuit with a load and battery reached cut-off voltage level than the circuit cut-off the power, but after few seconds circuit automatically recovered and creates continuous ON/OFF fluctuations (small delay 2-4 second), because without load 12v batteries voltage (trickle voltage) jumps up from the cut-off voltage (9.80v) to recovery voltage (10.00v) and turns on the circuit which creates problems.

           In future definitely I will try to improve the circuit. Still you can use this circuit with small load 10 watt to 15 watt.

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].

How to make 12V smart automatic battery charger circuit with auto start charging function

Image
 Smart Automatic 12 Volt Battery Charger Circuit with automatically start charging system circuit diagram: by "AMKP40 technology" YouTube. Friends this circuit try to keep the battery full charged everytime means automatically start charging when battery is discharge little bit and do not over charge the battery. This circuit's output voltage is fixed 14 volt DC however input voltage can be any between 14V DC to 18V DC. This circuit design and diagram is personal of "AMKP40 technology" YouTube channels.
