ANCEL BS400 Super Capacitor Starter for 12V Vehicles — Permanently Mounted, 1300A Peak, App Monitoring

The ANCEL BS400 is a permanently mounted super-capacitor starter that delivers instant high-current bursts to start 12V vehicles, protects your battery, and provides continuous health monitoring via an app.

Designed as a permanent, maintenance-free alternative to portable jump packs, the ANCEL BS400 uses super-capacitor technology to provide immediate, repeatable starting power without the drawbacks of chemical batteries. It mounts in the engine bay or connects with clamps, tolerates extreme temperatures, and communicates battery voltage, temperature, and start history to your phone so you can avoid unexpected no-starts.

How does the BS400 get a vehicle running when the battery is dead?

The BS400 stores and releases electrical energy through super-capacitors, enabling a very fast, high-current discharge that physically turns the starter motor even when the main battery is weak or at 0V. It delivers a peak burst of up to 1300A to cradle the starter circuit and revive ignition instantly.

• Super-capacitor physics: instant charge/discharge with no chemical lag.
• 1300A peak output to start engines up to 6.0L gas/diesel or 6.0T.
• Works from -40°F to 176°F, effective even with frozen or deeply discharged batteries.

What protection features keep my vehicle safe during use?

The BS400 features full circuit protection and built-in safeguards against reverse polarity, short circuits, over-current, over-temperature, and misconnections. IP65-rated housing protects the unit from water and dust when mounted under the hood.

• Comprehensive electrical protections to prevent damage from misuse.
• IP65 sealing for reliable operation in rain, snow, and dusty conditions.
• Permanent connection option reduces exposure to loose jumper leads and human error.

How does the app help me avoid being stranded?

The ANCEL app gives real-time battery voltage, temperature, and start history, plus push alerts when parameters indicate risk. Every start is logged so you can track long-term battery health and spot trends before a failure occurs.

• Live voltage and temperature readouts on your phone.
• Start-history archive to review past events and diagnose recurring issues.
• Remote Force Start control when you need an immediate assist without leaving the cabin.

What installation and daily-use options are available?

You can install the BS400 permanently using U-type terminals for continuous protection, or attach the included clamps for temporary use. It operates autonomously after installation and requires minimal maintenance; if the unit’s charge is low, a quick Type-C charge from a 5V/2A power bank restores starting capability in minutes.

• Permanent U-terminal mount for 24/7 readiness and battery protection.
• Included clamps for temporary or emergency connections.
• Type-C input for fast top-ups from standard power banks or chargers.

Who is this for? The ANCEL BS400 is aimed at vehicle owners who demand reliable starts without the hassle of portable battery packs—truck drivers, off-roaders, fleet managers, RV and van owners, and anyone who operates vehicles in extreme climates or who wants proactive battery monitoring. It’s ideal for users who prefer a set-and-forget, permanently mounted solution that reduces battery wear and significantly lowers the risk of being stranded.
