It need a 4056module to charge batteries.. A mobile charger wouldn't work..

@shahzadshabbir7827 Год назад

yes bro not work charger . mobile charger not charging battery So dont Try it.i suggest 4v battery

@carolcheny 6 лет назад

without BMS this is fire hazard.

@6006HDAD 6 лет назад

my led panel is heating too much on directly connecting to 4 volt battery solution plz

@ScienceTechnologyExperiments 5 лет назад

Ek 100 ohms ka resistor series men lagane se voltage kam kr k heating kam ki ja sakti hy mgr jb battery low ho jaegi to brightness bhi kam ho jaegi. islye heatup hone den aur kuch hi time bad battery jab 3.5 volt pr ajaegi to heating kam ho jaegi. Resistor na lagaen to acha hy.

There is a video how to get free charge protection board on my channel. Pls get & use if you are making it. Thanks.

@jumaakter9100 5 лет назад

Don’t make this rechargeable light because here is no protection feature for the lithium battery.after some days the battery will be blast.you can use 4056 charging module for making this rechargeable light

@NguyenDoan2529 6 лет назад

@prads34 7 лет назад

Will it work on 1w 6v solar panel with the tp4056 module for charging the cell?

@jaadugaming488 5 лет назад

@ScienceTechnologyExperiments 5 лет назад

Diode se one side current flow hota hy aur reverse nahi jata. Charger remove karogy to battery ki power charger use karne lagega aur battery discharge ho jaegi. Islye diode use karte hen. Thanks for comments & watching. Plz subscribe.

@funkatende 7 лет назад

I am seeing you using 100 0hms resistance as well as the diode, why are you using them,and if the battery was a 12 volts what would be the value of the resistance as well as the value of the diode.please help ☺

@ScienceTechnologyExperiments 7 лет назад

100 ohms resistance was used to reduce current for charging led which needs 3 volts approx while the diode was used to protect return voltage to flow one way.

@funkatende 7 лет назад

thank you again 😊

@funkatende 7 лет назад

great thank you

@KPBHAIG 6 лет назад

If you choose 12v battery the resistor value should 680ohms... And diode is for prohibit reversing voltage... You can choose 1N4007

@newcreative9543 4 года назад

Bro what is the benifit of diaod in this circuit as nokia charger already have it to regulate voltage?

@ScienceTechnologyExperiments 4 года назад

Diode doesn't allow return voltage and voltage flow one side. So battery voltage do not pass to charger but charger voltage pass to battery.

@artpie456 4 года назад

Do you think its okay not to put resistor in the LED plate? Please answer. Thank you in advance.

@ScienceTechnologyExperiments 4 года назад

I don't think its necessary because the battery will reduce voltage after few minutes if it is fully charged. Resister will lower its brightness. If you're thinking as a load resister, you can have it.

@artpie456 4 года назад

@@ScienceTechnologyExperiments I see. Can you please help me? I bought a small 30led solar motion sensor light (you can search it on google) and I replaced the pcb with TP4056. I'm worrying if I might damage the 18650 battery or the LEDs if I don't put any resistor in it. Do you have any thoughts in this? Please reply.

You can use 3 volts 1 watt leds 3 nos in parallel with star type heat sink either so total will be 3 volts 3 watts the same as I used.

@Mr.Unacceptable 7 лет назад

What stops it from overcharging? Do those batteries have the overcharge protection built in?

@ScienceTechnologyExperiments 7 лет назад

No protection circuit is added this time. 2 hours are enough for full charging. More time doesn't do any problem as I tried whole night. But don't charge more than 2 hours & check if its not heating up. You can use your own protection separately. Thanks

@Mr.Unacceptable 7 лет назад

They probably have the protection circuit on the positive end cap if that's the case. Overcharging is not a maybe thing.

@ScienceTechnologyExperiments 7 лет назад

You are right, in very rare cells there are invisible protection circuit on the negative end which can be compared with an ordinary cell in length which exceeds few millimeters & that is removable..

@ScienceTechnologyExperiments 6 лет назад
