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 a fixed frequency 108Mhz FM Transmitter Circuit or Simplest Walkie Talkie Transmitter Circuit at home; by "AMKP40 technology" YouTube. Friends this is a very simple stable frequency 108Mhz FM transmitter circuit diagram. In this circuit you can use 3.7V battery to 12V battery still perform this circuit fixed 108Mhz. If you use a 2N2219 transistor instead BC547 transistor you can get maximum range (approximately 300 meters) with a long antenna. You can build this circuit any structure or shapes without a problem.
