10A Dual Output DC-DC Converter for Electric Scooters

The 10A Dual Output DC-DC Converter is a multi-functional power management module engineered to convert high-voltage main traction battery power (36V to 72V DC) down to a stable 12V output while simultaneously supplying a dedicated 5V USB charging port. Designed for modern electric scooters, e-bikes, and e-rickshaws, this unit powers traditional 12V vehicle lighting, horn, and instrument display systems while offering on-the-go charging for smartphones, GPS units, and electronic accessories.

Featuring full protective circuit safeguards and high thermal dissipation efficiency (~90%), it eliminates the need for separate step-down converters and auxiliary USB power banks.

Key Features

Wide Universal Input Voltage Range: Supports 36V, 48V, 60V, and 72V DC battery setups seamlessly, providing wide compatibility across diverse light EV platforms.

Dual Output Architecture: Delivers a primary 12V DC output (up to 10A) for vehicle electronics along with a secondary 5V DC USB output (1A) for mobile device charging.

Smart USB Charging System: Features an integrated USB port to power cellphones, navigation displays, and camera units directly from the scooter's main pack.

Integrated Electronic Safeguards: Built-in protection mechanisms guard against over-voltage, over-current, output short-circuiting, and thermal overload.

High Conversion Efficiency (~90%): Minimizes heat generation and idle battery draw, ensuring maximum range for your electric vehicle.

Compact & Rugged Casing: Compact, lightweight form factor fits easily inside front cowlings, under seat compartments, or within battery enclosures.

Secondary Output (5V USB): Provides 5V DC at 1A for mobile device charging, GPS navigation units, and action cameras directly from the main battery.

1.Power Isolation & Safety Prep:

Switch off the main ignition key and disconnect the primary battery pack power connector before touching any wiring to prevent accidental electrical arcing or short circuits.

2. Mount the Converter Body:

Secure the converter to a flat, rigid section of the scooter frame (such as under the seat compartment or inside the front cowl) using mounting bolts or high-strength zip ties. Ensure it is placed in an easily accessible location for plugging in USB devices.

3.Connect Main DC Battery Input (36V–72V):

Connect the main input wires from the converter harness directly to your vehicle's main power supply terminals (switched through the ignition key):

Red Wire (+): Switched positive line from the main battery harness.

Black Wire (-): Negative ground line from the main battery harness.

4.Connect 12V Auxiliary Output Wiring:

Connect the 12V step-down output lines to the scooter's auxiliary electrical bus (supplying headlights, taillights, horn, and instrument cluster):

Yellow/Red Wire (+): 12V Positive feed to accessories.

Black Wire (-): Common negative ground return line.

5.Test 12V Accessories & USB Port:2 min.

Reconnect the main battery, turn on the ignition key, and verify that all 12V lighting/horn controls work properly. Plug a standard USB cable into the 5V USB port to test mobile device charging.

Keep the converter enclosure clean by wiping away mud, dirt, and road grime with a soft, dry cloth to ensure proper heat dissipation. Regularly inspect the wiring harness for any loose terminal connections, frayed wire insulation, or signs of heat wear. Ensure the rubber seal on the integrated USB port remains tightly closed when not in use to prevent water ingress and rust. Avoid high-pressure water jets directly near the USB slot or wiring joints during vehicle washing.
