About this item
- 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. Suitable 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: 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
- 5-LEVEL adjustable current & customized charging: This device offers 5 manual current selections: 2A, 6A, 10A, 15A, and 20A Mode. Select 2A for small batteries (Motorcycles, Lawn Mowers) to prevent overheating, or switch to 20A for rapid charging on large vehicles (75-400AH)
- Advanced Pulse Technology & Maintenance: The specialized mode uses high/low-frequency pulse technology to address vulcanization and support performance of 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
- Multi-vehicle compatibility: Compatible with a wide range of vehicles and equipment including cars, trucks, SUVs, motorcycles, marine boats, RVs, lawn mowers, and other vehicles with 12V or 24V battery systems ranging from 4AH to 400AH capacity
