Lithium battery's are used very much in all modern electronic device's and many electronic maker use Lithium battery in their projects specially 18650 model which have nice capacity and voltage range 3.7v to 4.2v so we need a voltage indicator for it .to see How much capacity left. but all voltage indicators are not so cheap .we all want simple working but cheap module so I will make a simple Lithium battery voltage indicator using 1n4007 and only led
What we need?
1.Red Led
2.Green Led
3.(1 k ohm)
4.(100 ohm)
5. 1n4007 diode 4pcs
Lithium ion battery are common used in electronic projects️ and they need to used correctly the voltage of Lithium batteries are from 3.7V to 4.2V and it needs to monitored because if Lithium battery's are over discharge to 3V they don't last very long so we need a Indicator or Voltage meter for them to see how much charge it has i maked a Super simple Voltage meter for Lithium batterys 18650 or it can be used for any 3.7V to 4.2 battery 🔚
