Product Details
✓FAST CHARGING : The Dumfume 14.6V 20A lithium battery charger is specifically designed for 12V (12.8V) LiFePO4 batteries, delivering fast and stable charging. Under ideal conditions, it can charge a 100Ah lithium battery in about 5 hours, making it a practical choice for RVs, campers, solar storage, backup power and off-grid systems.
✓0V ACTIVATION : The Dumfume LiFePO4 battery charger features 0V activation to help restart compatible LiFePO4 batteries that are deeply discharged or temporarily protected by the BMS. It can help resume charging when a battery cannot accept a normal charge after extended storage or deep discharge.
✓SAFE & RELIABLE : The smart LiFePO4 charger is equipped with over-voltage, over-current, short-circuit, overheating and reverse-polarity protection to help ensure safer and more reliable charging. A built-in cooling fan improves heat dissipation during extended charging, making it suitable for home, RV and solar battery systems.
✓EASY CONNECTION : The 12V lithium charger uses a secure Anderson connector for stable high-current charging and quick connection or disconnection. The plug-and-play design makes it convenient for RVs, campers, garages, solar setups and off-grid applications without complicated wiring.
✓CLEAR MONITORING : This 12V lithium ion battery charger is equipped with LED indicator lights in two colors, allowing for real-time monitoring of the battery charging status, making the charging status clear at a glance. Convenient for overnight RV charging, home energy storage and daytime solar battery charging.
