1>.Before installing the protection board,the batteries must be matched (the battery voltage difference should be less than or equal to 0.05V,the internal resistance difference should be less than or equal to 5mohm,and the capacity difference should be less than 30mAh).The smaller the battery voltage difference is,the longer the distance traveled.The working performance of the protection board will be better.
2>.The batteries should be connected in parallel and then in series,and ensure that the welding is correct(spot welding for 18650 batteries, soldering for other batteries),do not use screws,it is easy to burn out the IC of the protection board.
3>.If it is an old battery replacement board,please note that please confirm whether the battery is normal before buying.
4>.When installing,use a multimeter to check whether the voltage of each string of batteries is the same.
5>.Connecting the positive and negative poles of the charger may burn your charger or electrical equipment.It is required that your charger also supports anti-reverse protection.
6>.Please pay attention to the input and output voltage and load current conditions.The power consumption in the protection board does not exceed the allowable power consumption.
7>.If the wiring order is incorrect when connecting the battery for the first time,it may not be discharged.In this case,the connected charger can be activated to resume normal operation.
8>.When an overcharged battery and an overdischarged battery are mixed together,the battery becomes overcharged or overdischarged,and charging and discharging are impossible.
9>.Although this protection board has a built-in antistatic protection circuit,do not apply excessive static electricity to the protection board that exceeds the performance of the protection circuit.
