Why Batteries Still Go Low
Short trips and everyday electrical loads can use more power than your drive puts back.

You Need a Jump.

BS200—
Battery scenario 1 of 3
Battery Trouble Builds Long
Before Your Car Fails to Start.
Battery problems don’t happen all at once. They build over time through
everyday driving habits and real-world conditions.
Extreme Weather
Heat and cold can weaken starting performance.
Aging Battery
Older batteries lose reserve power over time.
Long-Term Parking
Vehicles parked for weeks can slowly lose battery readiness.
Frequent Short Trips
Short drives may not give your battery enough time to fully recharge.

Your Questions, Our Expertise.
Q1: How is BS200 different from a portable jump starter?
A portable jump starter is stored until a failure. BS200 stays connected to the vehicle and supports the battery during every start, while also providing battery monitoring through the app.
Q2: Do I need to charge it before installation?
For first use, charge BS200 to at least 80% before installation. Once connected, BS200 replenishes its own charge from the vehicle electrical system while you drive.
Q3: Which vehicles are compatible?
BS200 supports 12V lithium and lead-acid starting batteries (AGM, EFB, and GEL) in gasoline or diesel vehicles with naturally aspirated engines up to 3.0L or turbocharged engines up to 2.5L. Some hybrids are supported when the 12V battery cranks the engine. It is not compatible with 24V electrical systems or pure EV propulsion batteries.
Q4: Does it replace a damaged battery?
No. BS200 supports starting and reduces cranking stress, but it cannot repair a physically damaged battery or one that can no longer hold voltage.
Q5: Does the app require a subscription?
No registration fee or subscription is required. Connect through the ANCEL Super Starter app rather than the phone Bluetooth settings.
Q6: Does BS200 charge my car battery?
No. BS200 stores energy in its supercapacitors and supports engine starts. Use a separate battery charger or maintainer to charge your car battery.
Q7: How big is BS200? Will it fit under the hood?
BS200 measures about 9.20 × 3.69 × 1.97 in. Check that there is enough room near the battery to secure the unit and route its cables safely.
Q8: Can BS200 stay installed for a long time?
BS200 is designed for long-term under-hood installation and has a 3mA standby draw. For very long periods without driving, follow the user manual or contact ANCEL support for setup advice.
Q9: How do I connect BS200 to the app?
Download the ANCEL Super Starter app and connect through the app directly. Open the app, add the device and follow its setup instructions.
Q10: Can I extend the cables if they are not long enough?
Do not extend the cables yourself. Cable length, wire gauge, connections and placement affect performance. Contact ANCEL support if the original cables do not fit your vehicle.
