Avetlink AK Controller: Smart Voltage Detection for 48V / 60V / 72V E-Trikes
Designed for personal mobility vehicles in North America and Europe, the Avetlink AK controller makes battery management and controller replacement easier.
Most three-wheel scooter owners want a vehicle that works reliably without needing technical knowledge. If a controller lets the battery discharge too deeply, it can cause permanent damage. Replacing the battery can cost more than $500.
Repair shops face another challenge: stocking separate controllers for 48V, 60V, and 72V vehicles takes up shelf space and ties up money in inventory.
The Avetlink AK controller combines smart voltage sensing with support for all three voltage systems in one model. It simplifies replacement on compatible e-trikes, reduces the need to stock different voltage versions, and helps protect batteries from excessive discharge.

Why Choose the Avetlink AK 350W Controller for Mobility Scooters?
Automatic Battery Protection
The Avetlink AK 350W brushless controller automatically detects the battery system’s voltage and selects the corresponding undervoltage cutoff:

Battery System	Undervoltage Cutoff
48V	41V
60V	51V
72V	61V

When correctly matched to the battery, this protection helps prevent excessive discharge, which can damage lead-acid and lithium batteries and shorten their service life.
Smooth, Gentle Starts
The AK controller uses soft-start software to deliver power gradually when the throttle is applied. This helps reduce sudden jolts and provides more predictable acceleration for older riders and people with limited mobility.
Easier Installation
The controller uses a clearly arranged terminal-block wiring interface, making connections easier and reducing the need for specialized crimping tools. This simplifies replacement for repair shops and DIY users working with compatible 350W electric tricycles.
Simpler Inventory for Distributors
One AK model supports 48V, 60V, and 72V systems, reducing the number of controller versions you need to stock.
For example, instead of stocking 50 controllers for each of three voltages, you can stock 150 AK controllers that serve all three compatible voltage systems.
Technical Support for Installation
Avetlink provides technical documentation and wiring diagrams to help service teams complete installations efficiently and reduce vehicle downtime.
