Note 1: the B -, c-wires should be connected with thick wires, and ensure that the padand the positive
and negative poles of the corresponding equipment are correctly welded.
Note 2: before installing the protection plate, the battery must be well matched (the voltage difference of each battery shall not be higher than 0.05v, the internal resistancedifference shall not be greater than 5m 2, and the capacity difference shall be lower than 30mah). The protection plate is used to protect each battery string, as long as thevoltage of one battery string is too high or too low, it will be protected. The better theconsistency of the battery, the longer the power of the whole battery, and the better theperformance of the protection board.
Note 3: a single battery needs to be connected in parallel to the required number ofbatteries, and then the batteries can be used in series.
Note 4: when connecting three groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If not, please fill each group of batteriesseparately and use them in series. During the discharge test, the battery with the fastestvoltage drop is the differential battery.
Note 5: do not mix good batteries with poor batteries. The closer the internal resistanceis, the better the capacity of battery pack is.
Note 6: this protection plate cannot be used for lithium iron phosphate battery.
Note 7: the lithium battery protection board is strictly prohibited to be used in series.
