Protection Circuit Module ( PCB ) for 14.8V Li-Ion Battery Pack (4 cells with 6.5A limit )
Features and Benefits Protection Circuit Board for 14.4V Li-ion and Li-polymer battery pack Designed for 14.4V Li-ion or Li-Polymer battery Prevent 14.4V Li-ion or Li-polymer battery from over-charging, over-discharging and from discharging current more than 5A. Connection Instruction Port # Connection B+ To battery (+) B- To battery (-) P- Output (+) r Charger (+) P+ Output (+) r Charger (+) B1- To battery 3 (+) and battery 4 (-) B2- To battery 2 (+) and battery 3 (-) B3- To battery 1 (+) and battery 2 (-) Technical Specifications Overcharge Protection voltage 4.35V +/- 0.025V per single cell Overdischarge Protection voltage 2.4V +/-0.08V per single cell Overcurrent detection Protection 6.5 A (max) at 16.8V Continuous working current 3.0A (max) at 14.4V Over-charge protection response time 1 second (typical) Over-discharge protection response time 0.1 second (typical) Current consumption 30uA (max) Idle current 0.1uA (max) Internal resistance 130 m-ohms 0V charging capability Yes Working temperature -40 ~ 85 C Dimensions Length 50+/-0.3mm Width 16+/-0.2mm Thickness 3.5mm (max) Application Notes 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 the written agreement from us, please don't use this PCB for application in medical instruments, emergence 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.
