Images are for illustration purposes only. E&OE Overview Input port with micro USB female, can directly use mobile charger for input to the lithium battery, and still retain the input voltage wiring solder joints, can be very convenient.Connect the battery to B + B -, insert mobile phone charger to the USB Female then red light is charging and green is full of charged.This tiny module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as the 18650s that do not have their own protection circuit.Based around the TP4056 charger IC and DW01 Deep Drain Battery Protection IC this module offers a 1A charge current.The module cuts off the charging current when finished.Furthermore when the battery voltage drops below 2.4V the protection IC will switch the load off to protect the cell from running at too low of a voltage – and also protects against over-voltage and reverse polarity connection (it will usually destroy itself instead of the battery) however please check you have it connected Features Under Voltage Cut off / Deep Drain Protection Over Current Protection Adjustable Current Limit through R-Prog Over-voltage charging protection USB Micro Connector (with more commonly available USB cables) LED Status Indicator for Charging / Full charge status monitoring Specifications Module Name: Rechargeable lithium battery module Method: linear charge 1% Charging current: 1A Adjustable (Through 1.2k R3 RPROG Resistor) Charge Accuracy: 1.5% Input voltage: 4.5V-5.5V Full charge voltage: 4.2V Over-discharge / Deep Drain protection voltage: 2.5V Over-current protection: 3A Charging input interface: Micro USB Working temperature: -10 Degree to +85 Degree Polarity Reversal: Not Allowed Weight: 1.7g Dimensions: 28 * 17 * 1.1mm How to Use the Module: Connect micro/mini type C USB cable (depending on model), for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module Connect cell to charge to B+/B- pads on the right-hand side of the module A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side Important! Disconnect load when charging The Red LED indicates charging in progress, The Blue LED indicates charging has finished.
