Product Description

Meet the ultimate battery charger: The LVYUAN BC-400 PRO. As the most powerful in the series, this 12V/24V, 40A beast delivers incredibly fast charging for large batteries, coupled with sophisticated smart technology to protect, maintain, and revive your investment.

🔧 All-in-One Battery Solution
Your ultimate tool for battery care. From quick charging to long-term maintenance and reviving depleted batteries, the BC-400 PRO does it all.

📊 Large Intelligent LCD Display
Monitor every detail in real-time! The clear LCD screen shows ambient temperature, voltage, charging current, and battery capacity percentage, putting you in complete control of the charging process.

🛡️ Multi-Layer Safety Protection
Charge with absolute confidence. Our charger is equipped with six key protection systems: Short-Circuit, Reverse-Polarity, Over-Voltage, Over-Charge, Low-Voltage, and Over-Temperature Protection to safeguard both the charger and your battery.

🌡️ Smart Temperature Control
An integrated cooling fan automatically activates when the internal temperature exceeds 45°C (113°F), ensuring optimal performance and longevity by preventing overheating during intensive charging sessions.

⚡ Revive & Restore with 0V Start
Bring "dead" batteries back to life! Unique repair and desulfation modes can safely start charging from 0V, breaking down sulfate crystals on lead plates to restore battery health and extend its lifespan.

🔋 Smart Maintenance Mode
Perfect for seasonal storage. Once the battery is fully charged, the charger automatically switches to a float/maintenance mode, monitoring voltage and providing a trickle charge only when needed—zero risk of overcharging.

🚀 Versatile & Cost-Effective
One charger for countless tasks! Ideal for cars, trucks, motorcycles, lawnmowers, boats, and more. Compatible with 12V/24V Lead-Acid (AGM, GEL, SLA, VRLA) and 12V LiFePO4 lithium batteries (4Ah-400Ah). Save money and space with this do-it-all powerhouse.

    Perfect for work vehicles

    I use this every day in my work truck. It charges a battery for a backpack sprayer and a locator and I have had zero issues. Charges fast and it doesn’t buzz while running.

    Auch für induktive Lasten wie Staubsauger und Kühlschrank, Eismaschine geeignet

    Die ersten beiden Wechselrichter hier gaben trotz 500 W Angabe auf, wenn der Kompressor meiner Minieismaschine starten wollte. Im Betrieb zieht er nur 90 W. Erst dieser hier mit reinem Sinus schaffte das.

    works great

    It looked extremely small and cheesy, I thought it was broke. I am use to hearing the fan on my old one, but there was zero noise on this and I was actually surprised the speed of charge on my cell phone. The other one I also used my fast charger, but this one seems to be faster
