2A 5V Charge Discharge Module 3.7V 4.2V 18650 Li Battery Charging

SELAMAT BERBELANJA DITOKO KAMI 2A 5V Charge amp; Discharge Module 3.7V4.2V 18650 Li Battery Charging Boost Power Protection Board Charge voltage: DC 4.5 V-5.5 V (DC 5 V recommended) Charging current: 0-2.1A Load idle current: 100uA Total voltage: 4.2 V + -1%. Discharge current: 0-3.5A; Discharge current of discharge: 50uA Discharge efficiency: up to 96% Output voltage: 5 V Output current: 0-2.1A; Ambient temperature: -20 ° to + 85 ° Size: 25x16x4mm Weight: 2.3g PCB plate process: Shen Jin The module comes with a lithium battery protection function (the lithium battery does not need a protection plate, it does not matter if it has a protection plate) Overcurrent protection (OCP) Overvoltage protection (OVP) Short circuit protection (SCP) Protection against overtemperature (OTP) 1. In unload mode (The charging mode key function is not valid), the key port is activated once and the output is turned on; The port of the key is activated twice in a row and the output turns off. 2. The first time you access the load, the output turns on automatically. If the load is less than 50 ma, the output will turn off after 30 seconds; If the load exceeds 50 ma, the output will turn on continuously. 3. allows download while charging (note: output voltage gt; 4.7 / lt;5 V at this time) #2A #5V #Charge #Discharge #Module #3.7V #4.2V #18650 #Li #Battery #Charging #Boost #Power #Protection #Board SKU : 3131/1347635401622765568/55
