TP4056 4.2V 3A High Current Lithium Battery Charging Board Charger Module

Description TP4056 4.2V 3A High Current Lithium Battery Charging Board Charger Module Input voltage: DC 5V Output voltage: DC 4.2V 4 chips, with a reasonable turn-off voltage, the charging circuit for each chip set 750mA, total 3A. Input connected two 5A Schottky diodes, 5V standard voltage input chip heat ideal (3.8V battery test). Comes with over-temperature protection, short circuit protection. Product description 1: The battery can not be reversed! (On-board has been marked B B-) 2: Test current regulated power supply current can be seen, if only by connecting an ammeter in series with the circuit board 5V input positive. (5V power supply – Ammeter positive – Ammeter negative – positive circuit board 5V V ) 3: charging the battery voltage is greater than 4V, connect the battery, and then turn on the 5V power adapter, reverse the order can not charge properly. 4: As the current is large, please use thicker wire materials and a good connection, reasonable selection of adequate power adapter (15W or more). Avoid the adapter power output caused by insufficient charging current decreases. Note: the input reverse connection will not be available, the output reverse connection will damage the IC.
