    Hello,

    Does anyone have any schematics for building a Li-Ion battery charger? The battery is an Energizer model ER-C557, 7.2V, 2350mAh. It is used in a digital camcorder.

    Thanx!

    If you intend to tackle a charging circuit for lithium ion batteries then you will need to read up on the various requirements that are unique to this task. The more familiar you are with the subject, the greater will be your chance of success.

    Check out this article on Lithium-ion battery charging from the Battery University.
