MUY BUENO GENIO ,MI PREGUNTA ES SI SE PUEDE CARGAR DOS BATERIAS 18650 EN PARALELO CON ESTE CIRCUITO
@enriqueatala2567
Жыл бұрын
Hola, no contesta mucho este genio, el tema de dos a la vez depende que esten descargadas igual, como asi tambien igual marca, etc... es mas, este circuito debería ponerse un diodo a la salida positiva hacia la bateria ya que puede sobrepasar toda la carga hacia el circuito, hay muchos videos mostrando el peligro que puede ser cargar varias juntas, consejo carga de a una o hacete dos circuitos idem. saludos

La idea de cargar en paralelo es menos peligrosa que cargar en serie, pero como dice el otro comentario, es recomendable cargar una pila a la vez, solo por seguridad, saludos.
Could you redesign for Lifepo4 battery cell (3.65 Volt) Thnx.
sir you are make very well battery.charger.but sir plese lead acide battery charger make only for transistor and capacitor 4.2 volt cutoff voltage.

You can use any NPN power transistor, but take care of pin outs as different transistors have different pin configurations. 13005/13003 has pin (1 Base, 2 Collector, 3 Emitter)

@@CreativeTechos You have a great creativity in yourself . But it's just a waste of time and money tp4056 would cost around like 0.25 USD .And it will give 1A output and if you modify it just by changing resistor it can give 2A output the.

This circuit requires 5v dc and output voltage is dropped to 4.2 v using TL431 shunt regulator and 680R resistor, with limiting current with 47R. It requires 4.2v to charge a 3.7v lithium batteries.
