• 【IMPORTANT – NO BATTERY INCLUDED】This is a lithium battery charger equipped with a battery charge controller IC MCP73831T-2ACI/OT, the input charging connector uses Micro USB.
• Automatic Power-Down:There is an LED indicator on the charging board. When charging, the led indicator will be lit, and when the battery is fully charged, the led indicator will go out.
• The default charging rate of the charger is 500mA. If the battery is charged with a current that exceeds the battery charging current specification, it will cause the life of the lithium battery to decrease. So you can add some resistors on R1 (this would require cutting a trace) or replacing the surface mount resistor with a higher resistance value.
• It is for charging 3.7/4.2v single Lithium Ion/Lithium Polymer batteries.
• Plug the Micro USB cable into the USB port of the charging board, and insert the lithium battery into the JST port on the other end
