Avetlink AK Controller: Reliable Power and Battery Efficiency
Controller failures can interrupt work and increase repair costs. Rainwater can cause short circuits, while voltage problems may stop the vehicle unexpectedly.
The Avetlink AK intelligent controller automatically adapts to 48V, 60V, and 72V battery systems. It provides up to 60A peak current and a stated 50A continuous output.
The supplied specification lists automotive-grade IGBT modules and a three-layer protection design to support reliable operation.
Reported Performance
The original description reports:
- 200 hours of continuous operation without faults in rainy conditions, using a compatible dual-drive vehicle setup.
- 70% fewer controller replacements at a courier station.
- 15% longer driving range at that station.
These are reference results from the supplied material, rather than independently verified Avetlink results.
Three Key Features
- Automatic voltage detection: Recognizes supported battery systems without complicated manual setup.
- Sealed construction: A protective potting process provides a stated IP67 protection rating.
- Temperature-controlled cooling: The cooling fan automatically starts at 65°C.
Usage Tips
1. Follow the wiring diagram and connect the power leads with the correct polarity.
2. Inspect electrical connectors every month.
3. The source recommends motors rated 1200W or above. Confirm that the selected motor remains within the controller’s supported operating limits.

Frequently Asked Questions
Q1: Does it help protect the motor?
Dual overcurrent protection automatically reduces power during overload, helping protect the motor and controller.

Q2: Can it be fitted to older vehicles?
 Its Hall-sensor interface supports compatible electric scooter and tricycle drive systems. Check the motor, battery, and wiring before installation.

Q3: Can it handle loaded hill climbing?
The source reports smooth climbing with a one-tonne load using 50A continuous output. The slope angle and complete vehicle specifications are not provided, so this should not be treated as a universal load guarantee.

Q4: What warranty and repair service are listed?
The original terms include a three-year motherboard replacement policy and a 24-hour response for on-site repairs. Confirm Avetlink’s applicable terms and service coverage before ordering.
Reference Fleet Feedback
The supplied case describes Mr. Chen’s fleet in Shenzhen. After replacing its controllers, the fleet reportedly achieved:
- 62% lower annual vehicle maintenance costs.
- 90% fewer complaints about rainy-day breakdowns.
The source also describes use in orchard transport vehicles operating in mountainous areas.
