Parameters: 3.2V: Continuous working current: 18A Overcharge voltage: 3.65V ± 0.025V Instantaneous current: 30A Overcharge release voltage: 3.55 ± 0.05V Charging voltage: 14.4-15V Overdischarge voltage: 2.35 ± 0.08V Charging current: 1-10A Overdischarge release voltage: 2.55 ± 0.1V Balanced starting voltage: 3.405 ± 0.05V 3.7V: Continuous working current: 18A Overcharge voltage: 4.235V0.025V Instantaneous current: 30A Overcharge release voltage: 4.19 ± 0.05V Charging voltage: 16.8-17V Overdischarge voltage: 2.8 ± 0.08V Charging current: 1-10A Overdischarge release voltage: 3.0 ± 0.1V Balanced starting voltage: 4.19 ± 0.05V

Note: To achieve better consistency and balance, try to use a 15V switching source for charging (self stopping current below 30mA). Because the balanced current of the balanced IC is around 65mA, and most 14.8V iron lithium chargers on the market will automatically stop when the charging current is detected to be below 100mA, and there will be no charging before the balance is reached, resulting in an imbalance in the voltage of each group of batteries. Regarding the issue of voltage drop between the battery voltage and the output terminal voltage, the working principle of this type of protection board is negative electrode protection. Some newly assembled boards may experience a voltage drop of 0.1 to 0.3V, and cycling charging and discharging several times will reduce the voltage drop, which is a normal phenomenon. Try not to use a 14V power supply for the charger. A 4-string iron phosphate battery is 14.4V when fully charged. Charging with a 14V power supply may result in insufficient charging, and the protective board will not protect it. It has been charging for a long time, which can affect the battery life. Thank you for your understanding.
