Key Benefits
🛡️ Fully Potted Protective Design
Unlike standard plastic-shell chargers, the entire electronic circuit is embedded in potting material — protecting against moisture, condensation, dust, salt air, and vibration. Ideal for marine areas, roof boxes, garages, and outdoor solar systems.
⚡ 0V Battery Wake-Up
The charger detects deeply discharged LiFePO4 batteries from 0V and automatically starts a safe wake-up charging process — useful when a battery has entered protection or sleep mode after long storage or accidental deep discharge.
🔋 Fast 20A Charging
With a 20A charging current, it can fully charge a 100Ah LiFePO4 battery in around 5 hours — up to 4× faster than a standard 5A charger.
🌡️ Wide Temperature Range
Operates from -20°C to +50°C, covering typical conditions across Northern Europe, Southern Europe, and North America. Note: charging capability below 0°C depends on the battery's own low-temperature protection.
Typical Applications
- 🚐 RV / Motorhome: Fast charging for 12.8V LiFePO4 house batteries via 230V shore power
- 🏕️ Campervan: Compact Anderson output for direct battery connection in tight spaces
- ⚓ Boat / Marine: Fully potted housing resists moisture, salt air, and vibration
- ☀️ Off-Grid Solar: Grid backup charger when solar or wind power is insufficient
- 🏭 Industrial / Outdoor: Suitable for dusty, humid, or vibration-prone environments
⚠️ Important Notes
- Designed only for 12.8V LiFePO4 batteries
- Not compatible with lead-acid, AGM, gel, or NMC lithium batteries
- For 24V or 48V systems, please use a dedicated charger model
