About this item Balance setting 1 Manual equalization：Manually set the voltage, operate, and when the device is in normal condition, click “Manual Balance” to modify the “Voltage Value” (the set value must be within the effective range of the current type of battery) and click OK to realize the discharge > this set value Balanced to achieve the same voltage value of all serial bits with the set value. 2.Automatic Equalization：Automatic equalization is suitable for low-speed vehicles and small-capacity battery packs. The equalization power is 5%-30%. When the device is in normal condition, click “automatic equalization” to automatically identify the highest voltage and the lowest voltage. Put it down and keep consistent with the low voltage. 3.Charge equalization:Charge equalization, operation, charge equalization generally means that the voltage of the single cells in the battery pack is carried out when the battery is half-charged, and the setting parameters of charge equalization are as follows: 3-1. Balance parameters of lithium iron phosphate: Monomer overvoltage protection: 3.650V Monomer overvoltage recovery: 3.650V Forced equalization voltage: 3.650V The equalization start voltage is set to the lowest value of the string voltage = V, the voltage difference of the equalization monomer: 0.005V, and the proportion of the equalization current: 5%~100% 3-2, ternary lithium charging equalization parameters: Monomer overvoltage protection: 4.250V Monomer overvoltage recovery: 4.200V Forced equalization voltage: 4.250V Equalization start voltage: 4.000V Equalization monomer voltage difference: 0.005V Equalization current ratio: 5%~100% When charging equalization, the “battery negative pole” on the front panel of the machine must be connected to the battery pack’s general negative pole, the charger negative pole is connected to the machine’s front panel “charging negative pole”, and the charger’s positive pole is connected to the battery positive pole. Before entering the balanced state, the charging current must not exceed 25A, the charging current does not exceed 5A when it reaches a balanced start (lithium iron phosphate 3.450V/ternary lithium 4.00V), and the effect of small current balance will be better.
