TP4056-1A Micro USB Li-ION Battery Charger Module with Protection

Description This tiny module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as 16550s that do not have their own protection circuit. Based around the TP4056 charger IC and DW01 Deep Drain Battery Protection IC this module offers 1A charge current. The module cuts off 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 correctly the first time. 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 Technical 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 Current Regulation Chart RPROG (k) IBAT (mA) 30 50 20 70 10 130 5 250 4 300 3 400 2 580 1.66 690 1.5 780 1.33 900 1.2 1000 How to Use the Module Connect micro USB cable for power, or 5V DC to pads marked IN and IN- on left-hand side of the module Connect cell to charge to B /B- pads on right-hand side of 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, Green LED indicates charging has finished. Never charge your battery at a rate greater than 1C.
