Protecting Battery Health — Built to Outlast: Every start, your battery takes a hit. Once connected, the BS400 super starter takes the punch—handling up to 100% of brutal starting load while keeping voltage stable, eliminating voltage drops and preventing premature wear. Your battery lasts 300%+ longer. With 500,000+ cycles and a 70-year lifespan, one ANCEL BS400 engine starter outlasts multiple batteries — delivering decades of reliable jump-starts that pay for themselves.
Full Battery Monitoring — Always in Control: Open the ANCEL super starter's app anytime, anywhere to see real-time voltage, battery level, temp & start history. Get alerts before your battery dies. Every start is auto-logged in your vehicle's health archive for easy tracking. Think of this battery booster as a 24/7 security camera for your electrical system. End the blind guessing of a traditional jumper box. Early warnings prevent being stranded. You‘re always in control.
Once Installed, Works Automatically — Never Pop the Hood Again: Traditional car jump starters wait for failure. The BS400 doesn't. Once installed, this capacitor car starter automatically detects start-stop and handles deep discharges with no need for pre-charging, periodic checks or maintenance. For most starts, it works automatically. If the battery is critically low, tap "Force Start" app from your seat, and it delivers instant peak power to fire up your engine — without ever stepping outside.
Easy to Use — Never Fear a Dead Battery: You can permanently install it with U-type terminals for daily protection, or use the included clamps for temporary jumps—setup in minutes. Built with boost circuit technology, the BS400 supercapacitor pulls energy from a dying battery, stores it, and delivers an instant burst of power. Even at 0V, it starts your engine with 80%+ charge. If charge is low, just plug any 5V/2A power bank into the Type-C port, charge BS400 jump pack for minutes, and start.
