In our previous tutorials we learned how to customize a constant voltage while building a battery charger, while in the next section we understood how to add a customized constant current to the design for assuring a safe charging for the connected battery. In this section we'll discover how an auto cut-off may be added to a battery charger which is one of the most crucial aspects in such circuits.

In our previous tutorial we learned how to design and optimize a constant voltage feature for charging a particular type of battery, in this post we try to understand how to design and include a constant current feature for the same, which is another critical factor to be considered while making a customized battery charger circuit.
I have designed and published a variety of battery charger circuits in this website, however the readers often get confused while selecting the right battery charger circuit for their individual applications. And I have to explicitly explain each of the readers regarding how to customize the given battery charger circuit for their specific needs.

The post investigates a simple 2 pin oscillator circuit which may be inserted between the pickup coil and the CDI unit of a vehicle for achieving an induced multi trigger input in response to each signal from the pickup coil coil, this in turn is expected to enhance the sparking ability of the CDI coil. The idea was requested by Mr. Vimal.
