  • 20A High-speed charging for 12V & 24V: Built for efficiency. Delivers a robust 20A maximum current for 12V batteries and 10A for 24V batteries, charging 2x faster than standard 10A chargers. Ideal for rapidly charging heavy-duty batteries (4-400AH) in Cars, Trucks, SUVs, Marine Boats, and RVs. Intelligent detection automatically identifies 12V or 24V systems upon connection.
  • Exclusive tri-chemistry support (Li-Ion / LiFePO4 / Lead-Acid): Unlike standard chargers that only work with Lead-Acid, this versatile device features dedicated modes for 12.6V Lithium-Ion (Ternary/NMC) and 14.6V LiFePO4 batteries, as well as AGM, GEL, SLA, and Wet batteries. One charger for all your battery types—whether it's a custom lithium pack or a standard car battery.
  • 200-second booster mode: Never get stranded with a dead battery. Select the "BOOSTER" mode to deliver a quick, targeted charge for 200 seconds. The screen displays a clear countdown timer. Once the count ends and the screen shows "ON", your battery has enough surface charge to help jump-start the vehicle. Note: Designed for 12V lead-acid batteries.
  • Advanced Pulse Repair & Maintenance: Don't replace your battery yet. The specialized Repair Mode uses high/low-frequency pulse technology to remove vulcanization and restore lost performance to old, idle, or stratified lead-acid batteries. The charger also features Winter/Summer Modes, automatically adjusting voltage based on ambient temperature to prevent under-charging in cold or over-charging in heat.
  • Smart cooling & Multi-protection: Equipped with a built-in cooling fan to effectively dissipate heat during high-amp charging, ensuring stable performance. The smart microprocessor provides 24/7 safety monitoring, including protection against reverse polarity, short circuits, over-current, and over-heating. The LCD screen cycles through Voltage, Current, and Temperature data for real-time monitoring.
