【TRUE 20-AMP COMMERCIAL GRADE POWER】 Engineered for heavy-duty performance, Haisito delivers a massive 20A (12V) / 10A (24V) output, charging batteries 40% faster than older generation 20A chargers. Ideally designed for pickup trucks, SUVs, RVs, boats, and farm tractors. Why wait for outdated technology when you can power up instantly? 【UPGRADED HD SCREEN & VISUALIZED CHARGING】 Struggling to read dim screens on sunny days? We solved it. Our newly designed High-Definition LCD Display provides crystal-clear visibility day and night. Real-time monitoring of charging current, voltage, battery status, and internal temperature gives you total control at a glance. 【AI-SMART CHIP FOR LITHIUM (LiFePO4) SAFETY】 Stop using "dumb" chargers that damage your battery. Haisito features a Next-Gen Microprocessor that precisely detects battery chemistry. It offers optimized charging curves specifically for Lithium-Iron Phosphate (LiFePO4), AGM, Gel, SLA, and Wet batteries, ensuring 100% full charge without over-voltage risks. 【REVIVE DEAD BATTERIES WITH PULSE REPAIR】 Don't throw away your aging batteries. Our advanced High/Low-Frequency Pulse Repair technology removes sulfation and acid stratification, restoring lost performance for stronger engine starts. (Note: This is a professional CHARGER/MAINTAINER, not a jump starter. It cannot activate totally dead batteries with 0V). 【ALL-WEATHER PROTECTION & THICKER CABLES】 Built for the garage environment. Features a built-in temperature sensor that adjusts charging based on ambient heat or cold. Upgraded with Industrial-Grade Pure Copper Cables and heavy-duty clamps that stay cool and secure, solving the overheating issues common in generic chargers. The Haisito [2026 Upgraded] 20-Amp Smart Battery Charger and Maintainer is a professional-grade automotive tool designed to replace outdated 10A and slow 5A chargers. Engineered with a high-power commercial transformer, it delivers a true 20A output for 12V batteries and 10A for 24V systems, making it the ultimate solution for rapid charging and long-term maintenance. This device acts as a 3-in-1 battery solution: a high-speed battery charger, an intelligent trickle charger maintainer, and a battery desulfator reconditioner. Maximum Compatibility for Heavy-Duty Vehicles: Unlike standard car chargers, the Haisito 20A model is built to handle large capacity battery banks found in Pickup Trucks (Ford F-Series, RAM, Chevy Silverado), RVs, Travel Trailers, Motorhomes, and Box Trucks. It is also the perfect marine battery charger for Boats, Yachts, Trolling Motors, and Jet Skis. Additionally, it serves as a reliable tender for Motorcycles, ATVs, UTVs, Snowmobiles, Golf Carts, Lawn Tractors, and classic cars sitting in winter storage. Advanced Support for All Battery Chemistries: Our next-gen microprocessor provides optimized charging curves for Lithium-Iron Phosphate (LiFePO4), ensuring 100% charge without damaging sensitive BMS systems. It is fully compatible with all Lead-Acid batteries, including AGM (Absorbent Glass Mat), Gel, SLA (Sealed Lead Acid), Flooded (Wet), EFB, Calcium, and Deep Cycle batteries. Smart Repair & Safety Features: Featuring a distinct Pulse Repair Mode, this device uses high-frequency technology to remove sulfation and stratification from aging battery plates, effectively restoring lost performance to old batteries. The unit is equipped with a built-in temperature sensor for automatic voltage adjustment in hot or cold climates. Safety is paramount with our spark-proof technology, reverse polarity protection, and upgraded heavy-duty pure copper cables that prevent overheating—a common issue in generic 20A chargers.
