Rightly said

@Satyajit, This vdo is made by an amateur roadside unskilled professional. Your observation and suggestion is right. But I wish to add. Though adding a current limiting resistance will drop required voltage to high charging @ 0.5 amp or more, at less than 4 volt, but when the Lion cell is almost full charged, the charge current will drop down and so will be the voltage across the resistance. This will expose the Lion cell to high unsafe voltage exceeding 4.4 volt, causing failure of the Lion cell. Its better to use one or two diodes in series with the charger to allow only 4 volt to the cell and BMS can be avoided. The 4Volt LED strips are provided with limiting resistances, so need for additional current limiting resistance as suggested by you is unwarranted. Viewers who will risk constructing this illogical project will end up with a loss of double Lion cells and burnt LED strip because of the supply of higher voltage to it.

​@@madhusudangupta3661 I don't understand u mean charging without bms in unsafe or this battery cannot handle the load of leds?

​@@hamzayt210 Charging without BMS is unsafe. The suggested concept in the VDO will only damage the cell and risk the safety of the experimenter.

Bought from Kolkata market

Thanks

It is a 4 volt LED strip and 2pis lithium ion battery parallel connection and voltage output 3.7 and battery Full change voltage 4volt and LED strip negative and positive connection LED glow 🌟🌟 very simple project.

Thank you

Sir, you are connecting a small condenser with micro charging port. Please inform the name of small condenser. How many hours it will take to charge.

1 hours charging and full charge

Disturbing music. So switch off it

3.7volt battery

4 volt LED strip

Ok
