HIGH CURRENT 3A LITHIUM BATTERY CHARGING TP HIGH IN INDIA

3A high-current lithium battery charging board four TP   Basic parameters:   5V input, 4.2V output; charging red, then turn green.   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. Use and Test Considerations:   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
