Setting Voltage and Parameters on a Golden Motor Vector Controller

Okay, let’s set the voltage on a Golden Motor Vector controller.

1. First, click Start, then right-click on Computer and select Properties.

2. Next, open Device Manager. (Note: Windows versions vary, so this may be different for you.)

3. Once in Device Manager, look for Ports (COM & LPT) — you’ll see all available COM ports listed.

4. Now, plug in the Golden Motor USB cable. You’ll see it light up, and your computer will detect a COM port — for example, COM5.

5. If COM5 is not convenient, try plugging into a different USB port until a new COM port appears — for instance, COM8 with the CH340 driver.

6. Open the Vector controller software and select the correct COM port (e.g., COM8).

7. Click to connect. If you get an error, that’s normal. Just leave the program open.

8. Then, turn the bike’s battery key on. Once powered, the software will show data and numbers on the right side. You’re now connected to the controller. You can close any extra pop-ups.

Now, let’s go over the settings one by one:

Electric Braking: Do you want to use electric brakes for regenerative braking? Usually, this is set to Yes.

Reverse: Want reverse functionality? This is handy for trikes but can be left on with two-wheel bikes if you want. Enabling the reverse button takes some extra setup.

Pedal Ratio: This setting is for pedal assist — explained in another video.

Battery Voltage: This is the important one most people ask about.

Double-click the battery voltage field.

Select your battery voltage, like 36 volts.

Then, go up to Save Parameters and click it to apply.

Now your controller matches your battery.

To change back, select 48 volts and save again.

The controller uses this setting to protect your battery — it won’t work if voltage is out of range.

For example, max voltage might be 62 volts and minimum 42 volts for a 48V battery.

If you set it to 36 volts, you’ll see these max and min voltage numbers change (e.g., max 52, min 31).

These settings are for lithium-ion (LiPo 4) batteries. Different battery types, like sealed lead acid, need different settings.

Battery Current: Usually set around 25 amps — based on what your battery can handle safely.

This limits how much current the controller draws continuously.

The peak current is higher but only for brief acceleration bursts.

Wheel RPM: Default is around 380, but you’ll want to adjust this for your specific wheel size. There’s usually a chart to help with that.

Maximum Reverse Speed: Useful for trikes if you want to use reverse but generally not recommended for two-wheeled bikes.

Electric Brake Peak Phase: This controls regenerative braking strength.

Default is 50, good for rear wheels.

For front wheels, lower it to avoid slipping on slippery roads.

Acceleration (Upramp Speed):

Usually set at 100%, meaning full power immediately.

You can lower this to have smoother, slower acceleration.

This helps conserve power and prevent front wheel spin on takeoff.

When you’ve made all your changes, don’t forget to save the parameters before exiting the software.
