    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

    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.
