Battery Low Voltage Cutoff Circuit

By proper choice of r1 and r2 this circuit will work well for shut off voltages in the range of about 4 5 to 10 v.

Battery low voltage cutoff circuit.

Where v low is the low voltage shutoff threshold. Free shipping by amazon. Preventing lead acid batteries from being deeply discharged is absolutely key in terms of ensuring battery longevity. A low voltage battery disconnect lvd is a circuit which will automatically turn off the load connected to a battery if the battery voltage falls to low.

An ideal low battery cut off circuit should have zero on resistance zero power consumption when the switch is off and zero power. We sell a selection of user programmable low voltage disconnect circuits for 12v battery systems. When the battery voltage goes below this setpoint the output voltage on pin 3 will go high. Here is a very useful project of low battery cutoff or disconnect circuit.

Another pot is connected across the battery with its. It will automatically monitor the voltage of the battery and disconnect the battery from the load on the preset low voltage level of the battery. Aoicrie lipo battery checker 2pack rc lipo battery voltage detector with low voltage buzzer alarm and led indicator for 1s 8s iithium battery 1655. A pot is connected across the battery to be monitored with the wiper to pin 2 and adjusted so that the voltage on pin 2 equals 1 3 vcc when the battery is at the desired low voltage disconnect point.

I need a circuit that ll monitor voltage of a battery 3s lipo normal voltage of 11 1v minimum voltage of 9v but instead of a digital readout i only need 3 led s red yellow green for full 11 1v medium 11 0v 10v and low less than 10v and since it s for an airsoft gun i need it as compact as possible and preferably. 4 5 out of 5 stars 25.
