2V - 4V Battery Charger With Full Charging L.E.D Indicator.

HELLO FRIENDS IN THIS VIDEO I WILL SHOW YOU HOW TO
MAKE A 2V TO 4V BATTERY CHARGER...WHICH WILL INDICATE THAT YOUR BATTERY IS FULLY CHARGED AND IT WILL AUTO CUT OFF THE CHARGER SO THAT YOUR BATTERY WILL NOT BE OVER CHARGED AND CAN NOT BE DAMAGED...

Use a diode 1n4007 and connect it with the solar the white part of the diode should be battery side.. And then connect the batteries with the solar cell 1 or 2 and now the batteries ... Can be charged.. And the power of the batteries can not to solar cell but solar cell power can enters in the battery.. Or make a solar cell battery charger.. Thanks for watching. .

You can make this circuit and connect it with mobile charger in input and connect your battery as output. First adjust the circuit as i shown in the video.. Connect your full charged battery to the input of circuit and adjust VR as green red led glows Then when your battery reaches full charged level then red led will dimm and green led glows.
