Bluetooth App Monitoring:

• Connect the charger to a compatible smartphone through Bluetooth where supported by the charger and application.
• Monitor charging voltage from the mobile application.
• Monitor charging current in real time.
• Check battery charging status remotely within Bluetooth communication range.
• Use available app controls to monitor or configure supported charging functions.
• Bluetooth functionality and available app parameters can vary depending on the application and charger firmware.

Smart CC/CV Charging:

• The charger uses a Constant Current (CC) and Constant Voltage (CV) charging method.
• During the constant-current stage, the charger supplies controlled charging current to the battery.
• As battery voltage approaches the programmed charging voltage, the charger transitions toward constant-voltage operation.
• Charging current gradually decreases as the battery approaches full charge.
• Automatic charging control helps prevent continuous uncontrolled charging after reaching the programmed charging condition.
• For LiFePO4 batteries, the specified charging cutoff is 14.6V for a 12V 4S battery configuration.

LiFePO4 Battery Charging:

• Suitable for 12V-class LiFePO4 battery packs using an appropriate 4S configuration.
• 14.6V charging cutoff is suitable for a 4S LiFePO4 charging profile when specified by the battery manufacturer.
• A 30A charging current can significantly reduce charging time for appropriately rated high-capacity LiFePO4 batteries.
• The battery and BMS must be capable of accepting the charger's maximum charging current.
• Verify battery manufacturer's recommended charging current before using the full 30A output.

Lead Acid, AGM and GEL Battery Charging:

• Supports 12V Lead Acid battery systems.
• Compatible with AGM batteries.
• Compatible with GEL batteries.
• Suitable for SLA battery systems according to the supported charging profile.
• Select or configure the appropriate battery mode where the charger provides battery-type selection.
• Always use the correct charging profile for the specific battery chemistry.
• Do not assume LiFePO4 and Lead Acid charging profiles are interchangeable.

Recommended Battery Applications:

• 12V LiFePO4 battery packs
• 12V Lead Acid batteries
• 12V AGM batteries
• 12V GEL batteries
• 12V SLA batteries
• Solar energy storage batteries

• Inverter battery systems
• Electric vehicle battery systems
• Portable power systems
• Emergency backup power
• Home energy storage
• Workshop battery charging
• Industrial battery charging
• DIY battery projects
• High-capacity rechargeable battery banks

Charging Time Considerations:

• Charging time depends on battery capacity, initial state of charge, battery condition and actual charging current.
• A 30A maximum charging current is suitable for appropriately rated high-capacity batteries.
• For example, a 100Ah battery may theoretically require around 3.3 hours at a continuous 30A current, but actual charging time will be longer because charging current does not remain at 30A throughout the complete CC/CV cycle.
• LiFePO4 batteries may approach full charge relatively quickly during the constant-current stage, followed by a lower-current constant-voltage stage.
• Always follow the battery manufacturer's recommended charging current and charging procedure.

Usage and Safety Instructions:

• Connect the battery before connecting AC power.
• Disconnect AC power before removing battery connections.
• Do not use this charger with incompatible battery voltages or chemistries.
• Do not charge a deeply discharged or damaged battery unless the battery manufacturer specifically permits the charging procedure.
• Use the charger in a dry, clean and well-ventilated environment.
• Keep ventilation openings unobstructed.
• Do not cover the charger during operation.
• Keep the charger away from water and excessive humidity.
• Verify battery polarity before connecting the crocodile clips.
• Do not allow positive and negative battery terminals to short together.
• Disconnect the charger from AC power when not in use.
• Ensure the battery has an appropriate BMS when required, especially for LiFePO4 battery packs.

Important Compatibility Note:

• A 12V battery label does not always indicate an identical charging voltage across different battery chemistries.
• LiFePO4, Lead Acid, AGM and GEL batteries require different charging characteristics.
• Confirm the correct charging mode and voltage for the specific battery before charging.
• For a 12V LiFePO4 battery, the stated 14.6V cutoff corresponds to a typical 4S LiFePO4 configuration.
• The battery's BMS, maximum charging current and manufacturer's charging specifications should be compatible with a 30A charger.

Ideal for Applications:

• LiFePO4 solar batteries
• Home inverter batteries
• Solar backup systems
• IPS and UPS battery systems
• Electric vehicle batteries
• Battery energy storage systems
• Workshop battery charging
