Note

  1. Please note that the input and output voltage , and load current conditions, so power protection board does not exceed the allowable power consumption specifications .
  2. Situation may occur when connecting the battery can not be discharged . In this case , connect the charger can be restored to normal working condition.
  3. Case overcharge and over-discharge batteries battery becomes mixed with overcharge and over- discharge state status , will not be charged and discharged
  4. The protection board , although the built-in ESD protection circuitry, but please do not apply an electrostatic discharge protection circuit performance over the protection board
