5. Bedienungsanleitung
The VEVOR RV Power Converter offers dedicated charging modes and a fixed voltage Ausgabemodus.
Betriebsart auswählen:
Use the 3-Mode Adjustable Selector Switch on the side of the unit to choose your desired operating mode:
- Blei-Säure-Modus: For charging lead-acid batteries (12V-14.6V output).
- Lithium-Modus: For charging LiFePO4 batteries (12V-14.6V output).
- Feste Voltage Output Mode: Sorgt für ein konstantes Volumentage output. Selectable options are 13.0V, 14.6V, and 16.5V. This mode is suitable for powering 12V DC devices directly without a battery, or for specific charging requirements.

Multi-Stage Intelligentes Laden:
When in Lead-Acid or Lithium charging modes, the converter employs a multi-stagE-Ladevorgang zur Optimierung von Batteriezustand und -lebensdauer:
- Bulk-Modus: Lädt den Akku schnell auf ca. 80% seiner Kapazität auf.
- Absorptionsmodus: Lädt den Akku mit abnehmender Geschwindigkeit auf 100 % auf.asing current to prevent overcharging.
- Float-Modus: Maintains the battery at optimal charge, compensating for self-discharge.
- Speichermodus: Minimizes self-discharge and extends battery lifespan during periods of inactivity.
