hi friends
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 🔚

It is not OK. At 4.2 V, all 4 LEDs should have been on. At 3.5 - 3.6 V, just 1 led. Below 3.5 V, it doesn't have to illuminate any LED light . The Li-ion battery is destroyed if the voltage drops below 3.2 V .
