Matters and Notes for Lithium Ion Pack ,li polymer battery and military li ion battery packs.
Firstly, lithium ion battery can be seen everywhere in people's life. Various portable electronic products, on-board GPS, etc., lithium ion battery becomes an important part to maintain the operation of these tools. Proper charge and discharge of lithium ion battery can prolong battery life. The lithium ion battery power is maintained at 10%~90%, which is conducive to protecting the battery. This means that batteries for digital devices such as mobile phones and laptops do not need to be maximized
