MUY BUENO GENIO ,MI PREGUNTA ES SI SE PUEDE CARGAR DOS BATERIAS 18650 EN PARALELO CON ESTE CIRCUITO
@enriqueatala2567
@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
@einnarrodriguez4027

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.

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)
