Avetlink AK 350W Intelligent Six-Channel Controller
Short driving range and frequent breakdowns can make everyday transport expensive and inconvenient.
The Avetlink AK controller is designed for compatible low-power electric vehicles. It supports 48V / 60V / 72V battery systems, has a 350W power specification, and a maximum current of 25A.
The supplied test results report 20% longer driving range and more than 50% fewer failures. Applications include compatible dual-motor cargo tricycles and electric scooters used for daily commuting.
Three Key Features
- Six-channel, dual-loop control: Helps maintain stable current and reduce heat buildup.
- Automatic voltage detection: Recognizes supported battery voltages without manual voltage-setting changes.
- Temperature protection: Automatically reduces power when the monitored motor temperature becomes too high.
Usage Tips
1. Disconnect the battery before installation. Follow the supplied wiring diagram and terminal labels: the specified red power wire connects to positive, and the black power wire connects to negative.
2. Clean the cooling slots with a brush every month.
3. Take cooling breaks during long climbs, especially under heavy loads.
Frequently Asked Questions
Q1: Does it support dual-motor vehicles?
The AK controller supports compatible dual-drive systems and can control both motors. Confirm that the motor specifications match the selected controller configuration.

Q2: Can it withstand rain or water exposure?
The waterproof version is described as silicone-sealed, with a claimed immersion duration of 30 minutes. The source does not specify water depth or test conditions, so confirm the model’s protection rating before use.

Q3: Is installation straightforward?
Keyed connectors and a color-coded wiring diagram help simplify installation. The source estimates about 10 minutes for a compatible vehicle.

Q4: Can it upgrade an older vehicle?
It supports automatic motor matching on compatible electric scooters. The source includes vehicles up to 10 years old, although suitability depends on their motor, battery, and wiring.

Q5: Can it handle changing battery voltage?
The stated input range is 44V–75V. This describes the controller’s battery-side operating range; it does not establish protection against unstable mains electricity.

Q6: Can it be used with a higher-power motor?
Contact Avetlink before upgrading. Confirm the controller’s capacity and required settings rather than assuming a parameter change alone will support the larger motor.
