1)Do not apply the PCB which beyonds the specified criterias as above :
2)Sometime , the battery may not discharge when connected this PCB , please connect it to the charge and it can recover to the normal
3)The PCB may not work normarly When Mixing cells which were over-discharged or over-charged ,
4) Do not shock this PCB with big static even though the PCB has been designed with anti-stastic protection function.
