Product Description
The charger features a digital display showing battery voltage, charging current, and State of Charge (SOC). Controls include a Mode Switch Button for battery types/modes and a Current Switch Button for adjusting amperage (5A, 10A, 15A, 20A).
Charging Modes
- LFP: For LiFePO4 battery charging.
- AGM: For AGM battery charging.
- STD: For standard lead-acid battery charging.
- DC: 12V/24V DC power supply mode.
- Recovery Modes (AGM/STD): Used to repair old, damaged, or sulfated 12V lead-acid batteries using pulse charging.
- Low-Temperature Charging: Uses a small current (2A) initially for lead-acid batteries.
- Lithium Battery Activation: Automatically activates lithium batteries.
How to Use
- Connect the charger's AC interface to mains power. The charger enters standby mode.
- Press the MODE button to select the battery type/mode and the AMP button to set the desired current.
