CYSFETENA 36V 25A Brushed Motor Controller Kit — 36V 1000W Replacement with Twist Throttle & Voltage Readout

CYSFETENA's 36V 25A brushed motor controller kit is a direct replacement package that delivers smooth throttle response and a built-in battery readout for 36V, 1000W brushed ebike, scooter, or dirt-bike systems.

This kit is intended as a like-for-like replacement for vehicles that already use a 36V brushed motor and matching battery. It includes the controller, a pair of twist throttle handlebar grips, and two keys; it does not include a battery, charger, or universal wiring harness. Expect an aluminum-alloy housings, grooved heat-dissipation design, and a readout that shows battery voltage—note that the controller does not charge the battery, it only passes and displays the battery voltage to the motor.

How do I know this controller fits my vehicle?

Confirm compatibility by checking that your vehicle uses a 36V brushed (not brushless) motor and that your original controller plug and wiring layout match the photos or connector descriptions. This product is a replacement part, not an upgrade to convert brushless systems.

• Designed for 36V brushed motors up to 1000W (rated 25A)
• Compare physical connector shapes and pin counts before ordering
• Not compatible with brushless (3-phase) motors or controllers
• Suitable for many minibikes, scooters, and electric tricycles that specify 36V brushed systems

What are the main features and electrical limits of this controller?

The controller is rated at 36V nominal and 25A output with a maximum motor power roughly equivalent to 1000W. It has an integrated voltage display that shows the battery’s current voltage while the controller is in use, and the aluminum alloy case helps dissipate heat during operation.

• Nominal output ~36V; does not increase charging voltage
• Rated current: 25A; rated power: 1000W (brushed motor systems)
• Aluminum alloy housing with grooved design for cooling
• Includes twist throttle grips and two physical keys for security

How is installation handled and what tools or skills are needed?

Installation assumes your vehicle already has the appropriate 36V battery and compatible brushed motor. Wiring colors or connectors can vary by model; basic soldering or crimping skills are often required to attach the controller to the existing harness. If you’re not comfortable with electrical wiring, professional installation is recommended.

• Basic wiring skills (soldering/crimping) may be required
• Wiring colors/connectors can differ from originals—verify before cutting
• Does not include a full wiring harness, battery, or charger
• Comes with two keys and a left/right twist throttle grip pair for straightforward handlebar mounting

What safety and usage notes should I be aware of?

This controller passes the battery’s nominal voltage to the motor and displays the battery level but it is not a charger and will not modify charge voltage. Confirm your battery type and charger specifications before use. Using the controller beyond its rating (overvoltage or excess current draw) risks damage and voids expected performance.

• Controller displays battery voltage only—not a charging device
• Use your vehicle’s original charger appropriate to your battery chemistry
• Do not connect to higher-voltage packs or to brushless motors
• Professional installation reduces wiring errors and safety risks

Who is this for: This CYSFETENA 36V 25A controller kit is targeted at owners of 36V brushed electric bikes, scooters, minibikes, and tricycles who need a replacement controller and throttle assembly. It's ideal for DIY mechanics who can match connectors or do basic soldering, and for repair shops replacing worn controllers on compatible 1000W-class brushed systems. If your vehicle uses a brushless motor or a different voltage, search for a specifically matched controller instead.
