ANCEL 12V Supercapacitor Jump Starter BS400 — Permanently Mounted Unit, 1300A Peak, IP65

The ANCEL BS400 Super Starter is a permanently mounted 12V supercapacitor jump-starter that delivers instant high-burst power to start vehicles, protects your battery, and provides continuous battery health monitoring.

The BS400 replaces one-time jump packs with a compact, permanently connected unit that sits in your engine bay, ready to supply rapid, physical-charge bursts whenever your starter needs help. Designed to work across extreme temperatures and a wide range of 12V engines, it combines supercapacitor technology, rugged protection, and smartphone monitoring so you rarely, if ever, face a no-start situation again.

How does the BS400 actually start a car when the battery is dead?

The BS400 uses supercapacitors to store and release energy instantly through pure physical charge transfer, bypassing slow chemical battery recovery. Because it supplies a short, powerful burst of current, it reliably turns over engines even from fully discharged batteries or in very cold conditions.

• 1300A peak output suitable for most 12V gasoline and diesel engines up to 6.0L.
• Works from extreme temperatures (-40°F to 176°F) without degradation.
• Can start a battery at 0V with high-efficiency charge transfer.

What protection and durability features keep the BS400 safe in the engine bay?

The unit is engineered for harsh under-hood environments with IP65 water and dust resistance and multiple circuit protections to prevent damage from misconnections. Its rugged lifecycle and thermal tolerance mean it endures far longer than conventional batteries or portable jump boxes.

• IP65-rated enclosure guards against rain, dust, and splash exposure.
• Full short-circuit, reverse-polarity, and overcurrent safeguards.
• Rated for 500,000+ cycles and an expected multi-decade lifespan under normal use.

How does the BS400 help extend my vehicle battery’s life?

By absorbing the starter’s high current demands, the supercapacitor prevents large voltage drops and the repeated chemical strain that shortens battery life. That means the vehicle battery experiences fewer heavy discharge cycles and remains healthier over time.

• Handles up to 100% of starting load to reduce battery wear.
• Can increase battery service life substantially by avoiding deep stress starts.
• Automatic protection reduces parasitic damage during cold or repeated starts.

What remote or app features let me monitor and use the BS400?

The BS400 pairs with a smartphone app to show real-time voltage, temperature, charge state, and a log of starts so you can check battery health before a trip. If the battery ever approaches critical, the unit sends alerts and keeps a clear history of start events for diagnostics.

• Live readouts: voltage, battery level, temperature, and start history.
• Push alerts warn of low battery or abnormal conditions before failure.
• “Force Start” command from the seat allows one-touch engine starts when needed.

Who this is for: The ANCEL BS400 is ideal for owners of trucks, SUVs, off-road vehicles, RVs, and any 12V-powered vehicle who want dependable starts in extreme climates, reduced battery replacement costs, and a hands-off, permanently installed solution. It’s also a smart choice for fleet managers and anyone who tolerates no downtime — people who prefer preventive battery health monitoring and automatic assistance over manual jump-starts.
