Input voltage over 20V will damage the PCB. Please use the compatible charger for your battery pack. Pay special attention to your input and output voltage current to avoid PCB damage. When mixing over-charged batteries and over-discharged batteries together, PCB will be in dual state of over-charging and over-discharging. In this situation, charging and dis-charging are both disabled. Internal static charge protection circuit built into the PCB. However, do not subject the PCB to high static charge to avoid damage. Without the written agreement from us, please don’t use this PCB for application in medical instruments, emergence devices, auto and airspac
