Lithium ion battery charge and discharge process to set up the charging voltage upper limit and lower limit discharge voltage, therefore, the lithium battery(here refers to the lithium ion battery voltage divided into) protection lithium battery charging protection voltage and discharge voltage.
For single lithium battery, charging protection general standard voltage is 4.2 V, also has a better performance of lithium battery can be designed for 4.35 V, because the product consistency problem, in fact the charging protection voltage would allow a tiny floating space, such as between + / – 0.05 V.
At the time of discharge voltage protection standard is 2.75 V.
