Lipo Low Voltage Cutoff Circuit

Shut off a low current circuit beneath a certain voltage.

Lipo low voltage cutoff circuit.

The mcu will measure the voltage of the battery pack display the status leds good medium low and if the voltage is high enough it will latch the relay in the on position enabling the output. Get it as soon as thu sep 24. Different types of lipo batteries. Subtracting from lipo cell voltage.

Venom low voltage monitor for 2s to 8s lipo batteries. A separate mcu to cutoff lipo on low voltage. The monitoring circuit is made of a voltage regulator ams1117 50. That s a total of 6 7v which means the cut off would not engage.

So if you accidentally run your plane car too long you don t have your low voltage cutoff set properly in the esc electronic speed controller or you leave the power switch on forget to unplug the lipo get your plane stuck overnight in a tree the same tree three separate times for foolishly flying in areas too small because you are too. Switching between 2 power supplies upon dropping below cutoff voltage efficiently. That s why balancing is so important. The vehicle would continue to operate allowing you to further degrade the battery.

So when running your lipo make sure you have the low voltage cutoff enabled set up correctly and certainly don t continue to run it after the lvc has. Once armed the circuit is self fed by the relay so letting go the on button won t turn off the circuit. I used an external regulator because the lipo pack voltage when full is too high for the regulator on the arduino mini board. Also the coils of the relay take 150ma when energized.

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. Explanation of lipo cut off circuit.
