- simple Battery Charger 2x4.2V = 8.4V,
kali ini kita akan membuat lagi charger baterai 2s, baterai 18650 yang disusun secara seri sehingga menghasikan tegangan 8.4 volt. Rangkaian ini akan bekerja mengisi baterai hingga dan secara otomatis berhenti saat baterai telah penuh yaitu pada tegangan 8.4 volt yang dilengkapi dengan indikator nyala led saat penuh dan led redup saat baterai low.
sebelum melakukan pengisian, pastikan kedua baterai 18650 ini memiliki tegangan yang sama. rangkaian ini diberi resistor penahan arus sehingga tidak overload, pada video ini juga kita juga mengukur kuat arus pengisian, suhu pada baterai dan rangkaian
terimakasih telah menonton.

keren kak tutorialnya ,,maksaih nih nambah ilmu
if you use 2 resistors with lm317, one of 120R and the other of 680R with that you will have a value of 8.37v and you can replace the potentiometer
Very good method of yours, very good.
May God enlighten you, engineer
Gracias, estuvo muy fácil de entender , voy hacerlo ☺️
Nice
Thank you !
Thanks so much bro 🙏
good
Baterias de litio podem ser carregadas em série sem uma placa BMS ?
Please Sir,what changes could be done to increase the charging current?
Keren bang caranya
Terimakasih
👍👍👍🍻
pero las dos baterias de litium lo puedo conectar en serie no habra algun problema queria saber eso saludos
Please Sir can the voltage be adjusted to charge four 3.7 volts lithium ion batteries In parallel?
Parabéns muito bom
Good evening I saw your post about the 3.7 volt battery I have a 21 volt battery(5 battery 3.7=4.2vx5=21v) Can you tell me what resistors I need to change to make it work Thank you very much
Saya mau bertanya, apakah ini autocut ketika baterai sudah full sehingga tidak overcharge? Terima kasih
Ngecasnya pakai apa? Saya niatnya mau rakit juga, cuma bingung ngecasnya berapa volt? Ada adaptor bekas ps2 slim kan 9v takutnya kebesaran di volt & amperenya
Bang kalo power suply nya 19v bisa ? Atau ada yg di ganti ?
Mantap bang rankaiannya...bisa dibuatkan sirkuut baterai 18650 x 3...thanks....
Terimaksih atas idenya
2led?
Maaf bang, apanya yang salah ya? Kok pas posisi ngecas lampu indikatornya tetep nyala walaupun charger blm di colok
skema nya gan
Bang request charger yg 12,6v bang 🙏🙏
Terimakasih gan atas idenya..
kalo resistor kapurnya dihilangkan apakah rangkaianny masi bisa bekerja?
Masih bisa bekerja hanya saja Resistor ini berguna untuk membatasi arus dan juga mengurangi panas pada IC LMnya,,
Where tha scema?/ Pcb?
apakah ada pengganti selain bc547
S9013
Ada no WA ya bang
Bateray bekas laptop bisa
Bisa..
buen día amigo es necesario conectarlo con un cargador de 3amperios porque solo tengo de 1 amperio
