Avetlink AK 350W E-Rickshaw Controller with 48V / 60V / 72V Auto-Detection
Importers in Delhi, Dhaka, and Bangkok often face the same problem: stocking different controllers for different battery voltages takes up warehouse space, increases costs, and makes installation mistakes more likely.
Keeping separate 48V, 60V, and 72V controllers also makes inventory harder to manage. A low-quality 48V 350W replacement controller without proper undervoltage protection can allow excessive battery discharge. This can damage expensive batteries within months and reduce customer trust.

The Avetlink AK controller simplifies replacement by automatically detecting the vehicle’s battery voltage and adjusting its operating settings for 48V, 60V, or 72V systems.
One model serves several compatible vehicle configurations, helping distributors reduce controller variants and making voltage selection easier for dealers and repair shops. Built-in undervoltage protection also helps protect customers’ batteries from excessive discharge.
Why the Avetlink AK 350W Controller Makes Inventory Easier
Automatic Voltage Setup
The Avetlink AK controller automatically detects 48V, 60V, or 72V battery systems and selects the corresponding undervoltage cutoff:
- 48V system: 41V cutoff
- 60V system: 51V cutoff
- 72V system: 61V cutoff
Technicians do not need to change voltage switches or connect jumper wires, reducing manual setup errors.
Battery Protection
The controller cuts motor power when the battery reaches its low-voltage limit. With correctly matched battery settings, this helps prevent excessive discharge, extend battery service life, and reduce replacement costs.
Reliable Power Control
A 25A maximum current limit helps control current demand during loaded operation. The controller is designed to deliver smooth, consistent power while reducing the risk of excessive current and MOSFET overheating.
Bulk Supply for Distributors
The Avetlink AK 350W BLDC controller offers a practical option for distributors serving South Asian and Southeast Asian markets. Its durable design and low maintenance needs help reduce after-sales service costs.
