Delivers a powerful 25A output for 12V batteries and 15A for 24V batteries, charging significantly faster than standard maintainers. Perfect for larger vehicles including Trucks, SUVs, Boats, and RVs. Universally compatible with Lead-Acid (AGM, GEL, SLA, Flooded, EFB) and LiFePO4 Lithium batteries. Note: Intelligent chip automatically detects 12V or 24V connection. 5-LEVEL adjustable current & customised charging: Stop using "one-size-fits-all" chargers. This device offers 5 manual current selections: 2A, 8A, 20A, 25A, and Auto Mode. Select 2A for small batteries (Motorcycles, Lawn Mowers) to prevent overheating, or switch to 25A for rapid charging on large vehicles (75-400AH). The "Auto" mode intelligently detects battery internal resistance to choose the optimal charge rate. Emergency Booster Mode (Jump Start Assist): Dead battery won't start? Switch to the dedicated "BOOSTER" mode. It delivers a maximum current surge for 200 seconds to rapidly revive a depleted battery, helping you jump-start your vehicle immediately after the countdown ends. A must-have emergency tool for your garage. Note: Booster function is for 12V batteries only. Pulse repair & all-weather protection: Features an advanced 8-Stage Charging Process including a dedicated Repair Mode (16 hours) to help recover old, idle, or sulfated batteries and extend their lifespan. Built-in temperature sensors automatically detect ambient heat: it activates Winter Mode (<10°C) to boost voltage for a full charge in cold weather, and Summer Mode (>28°C) to prevent overcharging in heat. Durable aluminium housing & Active cooling: Unlike plastic competitors, our charger is built with a rugged Aluminum Alloy Shell and a built-in cooling fan. This design ensures superior heat dissipation during high-amp charging (25A), preventing overheating and ensuring consistent performance. Safety is paramount with protection against reverse polarity, sparks, short circuits, and over-charging.
