Description<br /><br />MINI USB input terminal with a female｣ｬ can be directly input to do with the phone charger rechargeable lithium battery｣ｬ and still retains the input voltage wiring pads｣ｬ can be very convenient DIY.<br /><br />Parameter<br /><br />Input Voltage: 4.5~5.5V<br />Full charging voltage: 4.2V<br />Max output current: 1A<br />Power Indicator: Red stands for charging｣ｬ Green stands for fullly charged.<br />Input interface: MINI interface<br />Item Size: 25mm*19mm.<br /> <br />It can be used for voltage 3.6 3.7V｣ｬ etc. 18650｣ｬ polymer and other lithium battery charge and discharge protection.<br /><br />Current Regulation<br /><br />RPROG (k): IBAT  (mA)<br />30:50<br />20:70<br />10:130<br />5:250<br />4:300<br />3:400<br />2:580<br />1.66:690<br />1.5:780<br />1.33:900<br />1.2:1000<br /><br />This module is used for single-cell lithium or lithium multi-section parallel｣ｬ charging ports can take power from USB.<br /><br />Instructions / Precautions<br /><br />Test current meter in series with the charge sheet only 5V input.<br />Charge current is best battery capacity 0.37C｣ｬ is 0.37 times the capacity｣ｬ such 1000mAH battery charging current 400 this is enough. The effect of excessive charging speed backward｣ｬ rushed over battery voltage out on much!<br />Not too small and too long charging connector wires. Such big connection resistance. Too thin｣ｬ then rushed over battery voltage out on much.<br />Connected to the battery the best
