5pcs 5V 1A Micro USB TP4056 18650 Lithium Battery Charging Board Charger Module

Description: 5 Pieces Enhanced Dual Function Micro-USB Powered 5V 1A 1S LiPo Battery Charger TP4056 Module With Internal DW01A Battery Protection IC This is an enhanced USB-powered module for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method. There are other types of modules on the market that use the TP4056 but lack any protection circuits or ICs. This module uses both the TP4056 and the DW01A Li-Ion battery protection IC, which together provide constant-current/constant-voltage (CC/CV) charging, along with protection against over-voltage, over-discharge, over-current and short circuits to protect the battery and the device that it is powering. The device to be powered by the battery is connected to the module's OUT+ and OUT- connectors and the battery is connected to the B+ and B- connections. When connected to USB power, the module provides up to 1A charge current until the battery is charged, then switches to a constant voltage mode to keep it charged. During use (when USB power is disconnected), if the battery voltage drops below about 2.4V (over-discharge), the DW01A protection IC disconnects the battery from the OUT connectors, disabling discharge to protect the battery from running at too low of a voltage and to protect the device being powered from an under-voltage condition. When the module is then connected to USB power, it will trickle charge the battery to 2.9V (the over-discharge release voltage), at which point the charge current will be linearly increased to 1A maximum and the module will reconnect the battery to the OUT connections, allowing discharge of power from the battery to a connected load. Although the module cuts output power from the battery during an over-discharge situation, it still allows trickle charging of the battery to occur. The module also protects against overcurrent and short-circuit protection - it will cut the output from the battery if the discharge rate exceeds 3A or if a short-circuit condition occurs. This module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as 16550s and 18650s that don't have their own protection circuit. It can charge two cells in parallel, however since the two cells share the charging current, they take twice as long to charge as a single cell. Specifications: Input: Micro USB female or + and - solder terminals Input voltage: 4.5-6V (recommended voltage 5V) Charge cut-off voltage: 4.2V + / - 1% (charges a 1S Lithium Ion Polymer Battery) Maximum charging current output: 1000mA (can be adjusted by changing the value of Rprog resistor - resistor values for various current levels are specified in the documentation and usage instructions included with the module) Battery overcharge protection voltage: 4.3V Battery discharge protection voltage: 2.4V Battery over-current protection level: 3A Board size: 27mm x 17mm x 3.6mm LxWxH (29mm x 17mm including USB connector overhang) Indicator LEDs: Red: Charging in progress Blue: Power on, charge complete Working temperature: -10C - +85C Operation: Connect a micro USB cable for power, or 4.5V to 6V DC to the pads marked IN+ and IN- on left side of the module Connect a battery to B+/B- pads on right side of module Connect a load (something for the battery to power) to the OUT+/OUT- pads on the right side If the load draws more than a few hundred milliamps of power, it should be disconnected when charging the battery The red LED indicates charging in progress, blue LED indicates charging is complete If the battery voltage drops below 2.4V, the module will disconnect the battery from the load, and will reconnect it when the voltage recovers to ~2.9V If the load draws more than 3A current, the module will disconnect the battery from the load Package Includes: 5X 5V Enhanced TP4056/DW01A 1A Micro USB Lithium Battery Charging Module
