Specifications
It is a simple and a low cost Lithium Battery charging breakout board.
It uses a Micro USB for connecting the breakout board to any computer or ‘USB wall adapter’.It works with linear charging method. It offers 1000mA charge current by default but it is adjustable from 50mA to 1000mA by soldering a resistor. The default resistor soldered in on the board is 1.2K Ohm. A resistance and current table has been shown below on this page. It is recommended that when you charge a battery, the current (in mA) offered by the breakout board is 37-40% of the battery capacity(in mAh). For example, if you are charging a battery of 1000mAh capacity, you should adjust the resistance in a way that the current offered is approximately 370mA-400mA.
