① Manual Equalization
Manually set the operating voltage. When the device is in a normal state, click "Manual Balance" to modify the "Voltage Value" (the set value must be within the valid range of the current battery type), and click OK to achieve discharge balance.
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 Charging Equalization
Charge equalization generally means that the voltage of the single cells in the battery pack is carried out when the battery is half-charged.
The setting parameters of charge equalization are as follows:
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%
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.

① Before balancing, please check whether the minimum voltage is lower than the battery over-discharge voltage. If it is lower than the battery over-discharge voltage, please charge the battery first. Balance the battery after it is fully charged, the effect will be better.
② During charging equalization, the "battery negative pole" on the front panel of the machine must be connected to the negative pole of the whole battery pack, the negative pole of the charger is connected to the "charge negative pole" on the front panel of the machine, and the positive pole of the charger is connected to the positive pole of the battery. The charging current shall not exceed 25A before entering the equilibrium state, and the charging current shall not exceed 5A when reaching equilibrium (lithium iron phosphate 3.45V/ternary lithium 4V). Small current balance effect will be better.
