5. Instrucțiuni de utilizare

The VEVOR WF-8955-AD-MBA features dedicated charging modes for different battery types and a fixed voltage output mode. Proper selection of the mode is crucial for efficient charging and battery health.

Selecting Charging Modes:

The main board includes a 3-mode selector switch. This switch allows you to choose between Lead-Acid, Lithium (LiFePO4), or Fixed Output voltage moduri.

1. Lead-Acid Battery Mode: Select this mode for traditional lead-acid batteries. The converter will utilize an intelligent 4-stage încărcare profile (Bulk, Absorption, Float, Storage) to optimize charging and maintain the battery.
2. LiFePO4 Battery Mode: Select this mode for Lithium Iron Phosphate (LiFePO4) batteries. This mode employs an intelligent 3-stage încărcare profile (Bulk, Absorption, Storage) specifically tailored for lithium battery characteristics.
3. Vol. fixtage Mod: This mode provides a constant output voltage, adjustable from 13.0V to 16.5V using the onboard potentiometer. Use this mode only if your battery manufacturer specifies a fixed voltage charge or for specific DC power supply applications.

Important: Always ensure the correct battery mode is selected before applying power to prevent damage to your batteries.
