Battery Equalizer for Lead Acid Batteries 48V 60V 72V

The Main Function of lead acid Battery Equalizer

HWB Series Battery Equalizer is Specially Designed for Lead Acid Batteries, 48V, 60V, 72V models available. It Efficiently Balances Battery Cell Voltage, enhances the system consistency, thereby prolong the battery service life.

It Helps:

1. To balance the charge, when the battery bank is charging, all battery cell voltages are equalizing to the same, to avoid laggard battery cell over-voltage or water loss.

2. Discharging equalization, when the battery is discharge, all battery voltage goes the same, to avoid lagging battery cell vulcanization.

3. Thermal runaway warning when the thermal runaway occurs, indicating that water should be filled.

Note:

Read this User Manual carefully before you hook up the balancer to your system.

Features of Lead Acid Battery Equalizer

1. Old batteries and new batteries can be mixed, no need to replace the whole battery group.

2. Battery capacity expansion

3. Obtain 12V voltage directly from the 48V/60V/72V battery bank (24V, 36V, etc. can also be obtained, must be in discharged state).

4. Charge the 48V battery bank directly with a 12V, 24V, 36V, 48V charger. (the wiring of the charging socket must be modified)

48V 20A balanced charge and discharge test summary (regular use)

1. The equalization charge ensures that the original unbalanced battery voltage is getting repaired. This prevents further damage from overcharging, water loss and heat generation.

2. Equalizing discharge ensures that the original unbalanced battery voltage is getting equalized, preventing further damage such as vulcanization and reverse polarity caused by over-discharge.

Although the battery bank is a strictly matched configuration, there are still differences. Balancing allows all the batteries to operate under normal conditions, the capacity of the unbalanced battery bank becomes the sum of all the batteries, the service life of the unbalanced battery is the same as that of the single battery.

Battery Equalizer Highlights

1. Backward Compatible: that means,48V Equalizer is compatible with 36V and 24V Batts. 60V Equalizer also can equalize 48V, 36V, 24V battery, 72V equalizer able to balancing 60V 48V 36V 24V batteries. When wiring the equalizer, connect the wire in steps from 48V,36V,24V,12V to 0V (Positive Pole to Negative Pole), once connection complete, the device start self-checks. The indicator light flashes in seconds, flash times same as the unit quantity.

2. Multiple Protection: over-voltage, over-current, over-temperature, Under voltage, overtime, and other abnormal state detection and protection, to ensure product safety.

3. Professional aluminum profile shell: special aluminum profile shell, surface oxidation process to enhance the product appearance, and also enhanced the protection and heat dissipation

Indicator Lit and Flash Meanings

1. Two Stage of Equalizer’s Starting Detection.

Stage 1, Battery Unit Quantity Detection, the indicator light flashes every two seconds, the number of flash time indicates the number of batteries.

Stage 2, The indicator light on 5S, equalizer mode in self-test.

2. Standby Status: indicator light stop 4S, flash 1S

3. Working status: light is Keep ON

Lead Acid Battery Equalizer Working Status:

1. Into Battery Discharging or Car driving status, and if the battery voltage difference reaches 200mV, it starts Battery Equalization.

2. any one battery cell voltage reaches or exceeds 13.6V, it starts equilibrium, All battery voltage drops to 13.4V, stop the balance

3. Anti-bubble status, dedicated charger terminal access to the qualified charger, start balance.

4. Normal charge start mode also supported by anti-bubble status.

5. Anti-charge type only for the 48V (4 battery banks) or higher, when the batteries are less than 4, then it will not support the anti-charge access start, switch to the normal status.

Main functions and Technical Parameters:

1. Balance battery: Equalization Current 10A

2. Temperature Protection: 158 °F (70 °C)

3. Over-current protection:12A

4. Over-voltage protection, any battery cell voltage exceeds 15.8V

5. Under voltage protection, all battery cell voltage is lower than 9V

6. Thermal Runaway Protection

Note: Protection here generally means that the equalizer is stopped. When the equaliser enters the protection state, the indicator flashes once every second for a total of 10 times.
As soon as it exits the protection state, it will return to the normal state. However, if thermal runaway is detected, it must wait for all battery voltages to fall below 13.4V, then stop flashing every second and exit thermal runaway protection.

Battery Equalizer Installation Instruction

Before installation, ensure that the Balancer is protected against short circuits (as shown in the pictures above). The wires can be wrapped in electrical tape or transparent plastic to prevent accidental contact between two wires and to prevent the fuse from blowing when the cable is connected.

The illustration above shows how the equalizer is connected. Note that the wiring must start from the yellow wire (48V Positive End) and the black wire must be connected last. When removing the equalizer, the black wire must be removed first.
