Parameter? Single Cell overcharge protect voltage:  4.23 - 4.28V   Single Cell overcharge rotect recover voltage:  4.08 - 4.18V  overcharge protect delay:  0.5 - 1.5S   Single Cell over-discharge protect voltage:   2.72 - 2.88V   Single Cell over-discharge rotect recover voltage:   2.9 - 3.1V  overcharge protect current:  60A   over-discharge protect current: 60A  over-discharge protectdelay: 0.5 - 1.5S temperature protect: YES disconnect protect: YES shortage protect: YES shortage delay: 100 - 600?S shortage protect recover: YES Charging current:  25A discharging current: 25A charging voltage :  12.6V for 3S BMS board 16.8V for 4S BMS board 21V for 5S BMS board Package includes: 1 x 3S BMS board Note: A single battery needs to be connected in parallel to the required number of battery packs, and then the battery packs are used in series. When connecting 2 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are different, please fill each set of batteries separately and use them in series. In the discharge test, the battery with the fastest voltage drop is the poor battery. This protective plate cannot be used for lithium iron phosphate batteries. Lithium battery protection board is strictly prohibited to be used in series.
