Regen Braking Setup Guide (ADC Input — Off-Throttle Regen)

Throttle Calibration Guide + Motor Setup Guide REQUIRED Before Doing This

⚠ READ THIS FIRST

Regen braking uses Battery Current Regen Max Amps.

If this value is NOT set correctly in Motor CFG, you can:

• Trigger BMS Shutdown
• Cut throttle mid-ride
• Damage your battery
  

If you are not sure, please see the Motor Setup Guide first.

Step 1 — Connect to Your VESC

1. Turn ON your kart / VESC.
   
2. Open the VESC Tool App.
   
3. Tap CONNECT and select your VESC.
   

Step 2 — Switch to ADC Control Mode

1. Scroll the top bar to App CFG.
   
2. Tap General.
   
3. Change App to Use → ADC.
   
4. Change Control Type → Current No Reverse Brake Center.
   

What this means:

• The throttle’s “center point” determines when regen activates.
  
• By default, regen begins at half throttle on the return stroke — we will fix that in the next step.
  

Step 3 — Adjust Regen Activation Point

To make regen activate immediately when you release throttle, adjust the center:

1. Under the ADC area, there is another General box.
   
2. Tap this box → select Mapping.
   

You will now see two important values:

• ADC1 Start Voltage
  
• ADC1 Center Voltage
  

Recommended Setting

Set ADC1 Center Voltage to 0.10V above ADC1 Start Voltage.

Example:

• Start Voltage: 0.90V
  
• Center Voltage: 1.00V
  

This ensures regen activates instantly off-throttle, not halfway.

1. Tap Write — settings will not apply unless you write them.
   

Step 4 — Set Regen Strength Using Profiles

Regen braking force is controlled by motor current scaling inside Profiles.

1. Scroll to the Profiles tab (top bar).
   
2. Tap Add Profile.
   
3. Adjust Motor Current Scale → start with 5–15%.
   
   This percentage determines regen braking intensity.
   
   You can increase or decrease based on preference.
   
4. Tap Save Profile.
   
5. Tap Use Permanently.
   
   (If you don’t, the profile will reset when reconnecting.)
   

Step 5 — Confirm Battery Regen Limits (IMPORTANT)

Regen is only as safe as your battery’s regen capability.

Go to: Motor CFG → General (Current mode)

Check Battery Current Regen Max.

Recommended Value

• -5A is safe for most lithium-ion packs.
