About this item

• 20A High-power charging for 12V & 24V: Experience the speed of 20 Amps. Delivers a robust 20A output for 12V batteries and 10A for 24V batteries, fully charging a 100Ah battery in roughly 5-6 hours—twice as fast as standard 10A chargers. Ideal for large capacity batteries (up to 300AH) found in Trucks, RVs, Boats, and Agricultural Vehicles.

• Optimised for LiFePO4 & Lead-acid: One charger handles them all. Engineered with specific algorithms for LiFePO4 Lithium batteries and all 12V/24V Lead-Acid types including AGM, GEL, SLA, Wet, and Deep Cycle batteries. Whether maintaining a lithium battery in your camper or a standard battery in your pickup truck, it ensures a safe and full charge.

• 7-stage smart charging & Auto-memory: Features a microprocessor-controlled 7-stage charging process that automatically diagnoses, charges, and maintains your battery to maximize its lifespan. The built-in Auto-Memory function remembers your last selected mode, so it automatically resumes charging the same way if power is interrupted or when you plug it in next time.

• Pulse Repair & Desulfation: Revitalize your battery. The dedicated Repair Mode (16-hour cycle) uses advanced pulse technology to help break down sulfation crystals on battery plates. It is designed to recover old, idle, or stratified lead-acid batteries and restore their capacity, saving you the cost of premature battery replacement.

• Smart protection & Active cooling: Built for worry-free operation 24/7. The system includes comprehensive protection against reverse polarity, short circuits, over-charging, and over-temperature. Equipped with a built-in cooling fan to effectively dissipate heat during high-amp (20A) operation, ensuring the device stays cool and efficient.
