Application Notes We do NOT provide engineering support for this item. It is up to the purchaser to determine suitability and manage the use of this product. If this product is modified (soldered onto) it cannot be returned.

Do not subject the PCB to input voltage over 20V. INput voltage over 20V will damage the PCB Please use the compatible charger for your battery pack. 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. But not subject the PCB to high static charge to avoid damage. Without a written agreement from us, please don't use this PCB for application in medical instruments, emergency devices, auto and airspace vehicles or other device that might have impact on human body. Because of the very high energy density, Li-Ion Battery pack must be connected to a protection circuit module to prevent accidental battery explosion caused by over-charging or over-discharging.
