Can be set to charge 2 or 3 series of lithium batteries <br>5. 2 series balanced charging <br>6. Adjustable charging current <br>7. Input overvoltage and undervoltage protection <br>8. Adjustable charging timeout protection <br>9. Output overcurrent, overvoltage and short circuit protection <br>Introduction: <br>This module is applicable to 2S or 3S 3.7V lithium battery. Through short circuit setting, the default is 2 strings. When using 2 strings, the module can use its own battery equalization function, which is very practical. Type C port and welding line can be used for input. When the Type C port is connected to the fast charging power supply, the charging voltage is automatically adjusted to improve efficiency. If the input voltage of the welding wire input is less than the battery voltage, the module can only work in the boost state.<br>1、APPLICABLE BATTERY: The battery charging boost module supports 2S and 3S battery, and has the balance function when connecting 2S batteries, which is stable and reliable. <br>2、CURRENT SETTING: The green arrow indicates that the default current of the two parallel settings is 100K (0.9A) and 180K (0.5A). The resistor can be removed or replaced as required. <br>3、CHARGING TIME: Set the charging timeout time. There is no timeout time by default. Set the ROT resistance value, 68K is 4 hours, 120K is 12 hours, and non stick is 24 hours. <br>4、HIGH EFFICIENCY: The module supports Type C port access and QC fast charging, which can automatically adjust the charging voltage and improve the charging efficiency. <br>5、LED INDICATOR: The red light is on when normal, the blue light is on during charging, the blue light is off when full, and the blue light flashes when abnormal is detected.5 x Battery Charge Boost Module
