Battery-powered Pro Roller

The T800 Pro Battery Break-in Bench takes motor preparation to the next level: real autonomy, total control, and no dependence on a power outlet.

When you are serious about your slot cars, motor break-in is not just a formality; it is a critical part of the preparation. The T870040 from T800 is designed exactly for that: to provide the tuner or club driver with an autonomous, precise, and comprehensive tool, both on the workbench and on the track itself.

Technical Features

• 9900mAh Lithium-Ion Battery with included charger. Autonomy for long break-in sessions without interruptions.
• Adjustable 4mm Banana Outputs from 0 to 12V: fine voltage adjustment for progressively and controlled motor break-in.
• Fixed 4mm Banana Outputs at 12V: for direct applications without the need for regulation.
• USB and USB-C 5V Ports: charging of mobile devices or powering workshop accessories.
• Backlit Digital Display: real-time monitoring of supplied voltage, current consumption in amperes, and battery charge level.
• Polarity Reverser on adjustable outputs: reverses the motor's direction without touching the wires, greatly speeding up break-in in both directions.
• Built-in Protection Fuse and illuminated switch for immediate access.
• Compatibility: scales 1/32 and 1/24.

Control and Precision in Motor Break-in

The ability to adjust the voltage from 0 to 12V via the adjustable banana outputs allows for the application of the most demanding break-in protocols: smooth starts at low voltage, gradual increments, and direction reversal cycles without manipulating the wiring. The digital display provides a clear reading of the actual voltage delivered and the amperage consumed at all times, key data for detecting anomalies in the motor and verifying that the break-in is progressing correctly.

The polarity reverser is one of the most appreciated features in real use: with a simple turn, the motor reverses its direction. In a standard break-in, it is recommended to alternate the direction of rotation to balance the wear of the braids and the collector, and doing so without having to cross wires is a practical advantage that makes a difference in long sessions.

Versatility Beyond the Workbench

Beyond pure break-in, the T870040 functions as a complete portable power station for the pit. Its USB and USB-C 5V outputs allow you to keep your mobile phone, tablet, or any electronic workshop accessory charged, turning the Pro Break-in Bench into a high-capacity Power Bank that accompanies the toolbox during any competition day or club session.

Its robust construction and the great autonomy of the battery make it especially suitable for endurance races and preparation marathons where access to the electrical grid is not always convenient.

Ideal for…

• Tuners and drivers who break in motors for slot cars in 1/32 and 1/24 scales.
• Club competitors who need a ready-to-go autonomous tool.
• Slot workshops where an independent break-in setup from the main power source is desired.
• Endurance days or events where comfort in the pit makes a difference.

Frequently Asked Questions

Is the battery charger included?

Yes, the T870040 comes with its specific charger for the 9900mAh Lithium-Ion battery.

Can I use it with 1/24 scale cars as well as 1/32?

Yes, the T800 Pro Break-in Bench is compatible with motors of both scales, 1/32 and 1/24.

What is the purpose of the polarity reverser?

It allows you to reverse the motor's direction directly from the device, without the need to cross or change the connection wires. It is very useful for applying break-in cycles in both directions quickly and safely.

Is the digital display always visible?

The display features high-visibility backlighting, making it easy to read the voltage, amperage, and battery level even in low-light conditions.

Can I charge my mobile phone while breaking in a motor?

Yes. The USB and USB-C outputs operate independently of the banana outputs, so you can power an external device simultaneously while breaking in a motor.

Does it have any electrical protection system?

Yes, it includes a protection fuse and an illuminated switch to ensure safe use of the equipment.
