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.
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.
