Smart CC/CV Charging:

• Uses a Constant Current (CC) and Constant Voltage (CV) charging method.

• During the constant-current stage, the charger supplies controlled charging current to the connected battery.

• As battery voltage approaches the programmed charging voltage, the charger transitions toward constant-voltage operation.

• Charging current gradually decreases as the battery approaches its full-charge condition.

• Automatic charging control helps prevent uncontrolled continuous charging after reaching the programmed charging condition.

• The specified LiFePO4 charging cutoff is 29.2V, suitable for an 8S 24V-class LiFePO4 battery configuration when supported by the battery manufacturer.

• CC/CV charging is commonly used for rechargeable battery systems requiring controlled current and voltage charging.

LiFePO4 Battery Charging:

• Designed for 24V-class LiFePO4 battery packs using an appropriate 8S configuration.

• The specified 29.2V charging cutoff corresponds to 3.65V per cell for an 8S LiFePO4 battery pack.

• 20A charging current can provide relatively fast charging for appropriately rated 24V LiFePO4 batteries.

• Battery capacity and BMS current rating should be suitable for a maximum 20A charging current.

• Check the battery manufacturer's recommended charging voltage and charging current before operation.

• Ensure the battery BMS supports the selected charging profile.

• Do not use a LiFePO4 charging profile with a battery chemistry that requires a different charging voltage.

Lead Acid, AGM, GEL and SLA Battery Charging:

• Supports compatible 24V Lead Acid battery systems.

• Suitable for supported AGM battery configurations.

• Compatible with GEL battery systems when the charger profile is appropriate.

• Supports SLA battery systems according to the charger's available charging characteristics.

• Always select or configure the appropriate battery type where battery-mode selection is provided.

• Use a charging profile appropriate for the specific battery chemistry.

• LiFePO4, Lead Acid, AGM and GEL batteries have different charging requirements and should not be treated as interchangeable.

Bluetooth App Monitoring:

• Connect the charger to a compatible smartphone through Bluetooth where supported by the charger and application.

• Monitor battery charging voltage from the mobile application.

• Monitor charging current in real time.

• View battery charging status through the smartphone application.

• Monitor charging progress without repeatedly checking the charger display.

• Available Bluetooth functions may depend on the compatible application and charger firmware.

• Bluetooth communication operates within the supported wireless range of the charger and smartphone.

Charging Indicators:

• Red LED: Indicates active charging according to the supplied specifications.

• Green LED: Indicates full-charge status.

• Audio Beep: Provides an audible notification when charging is complete.

• Bluetooth App: Provides additional charging information where supported.

• LED and audio indicators provide a convenient way to identify the current charging condition without relying exclusively on the mobile application.

Built-in Protection Functions:

• Overvoltage Protection: Helps protect the charger and connected battery system against excessive voltage conditions.

• Overcurrent Protection: Helps limit excessive output charging current.

• Overload Protection: Helps protect the charger during abnormal operating conditions.

• Short-Circuit Protection: Helps protect the output circuit if the battery connection or charging output is accidentally shorted.

• Protection functions are intended to reduce the risk of damage during abnormal electrical conditions, but correct battery connection and charging configuration remain essential.

How to Use:

• Confirm that the battery is a compatible 24V battery system.

• Identify the battery chemistry before connecting the charger.

• Verify the battery's recommended charging voltage and maximum charging current.

• For 24V LiFePO4 batteries, confirm that the battery uses a suitable 8S configuration and supports a 29.2V charging cutoff.

• Inspect the battery terminals, charger cables and crocodile clips for damage or loose connections.

• Connect the positive crocodile clip or battery lug to the battery positive terminal.

• Connect the negative crocodile clip or battery lug to the battery negative terminal.

• Confirm correct polarity before applying AC power.

• Connect the charger to the battery before connecting the AC input.

• Connect the charger to a suitable AC 110–220V, 50/60Hz power source.

• Select the appropriate supported battery charging mode if the charger provides battery-type selection.

• Start the charging process.

• Monitor charging voltage, current and charging status through the Bluetooth App where available.

• The red LED indicates charging operation.

• When the green LED and audio notification indicate full charge, charging is complete according to the charger's control system.

• Disconnect the AC power before removing the battery connections.

• Remove the battery clips only after the AC input has been disconnected.

• Avoid reversing battery polarity.

• Do not connect incompatible batteries or batteries with charging specifications outside the charger's supported range.
