Regen Brake Setup (Separate Pedal or Thumb Throttle)

Requires ChargedUp Regen Brake Cable — Separate Input for ADC2

⚠ Required Hardware

To use a separate brake pedal or thumb throttle for regen braking, you must use this cable:

👉 ChargedUp Regen Brake Cable:

https://chargedup3d.com/products/75100-v2-regen-brake-cable

This cable splits the throttle input into two ADC channels (ADC1 = throttle, ADC2 = regen brake).

Step 1 — Identify the Correct Connectors

The regen brake cable has two throttle connectors:

Connector 1 — Regular Throttle (ADC1)

• Wires: Black / White / Red
  
• This connects to your main throttle pedal on the kart.
  

Connector 2 — Regen Brake Throttle (ADC2)

• Wires: Contains BLUE wire
  
• The one with the blue wire is your regen throttle input (ADC2).
  
• This connects to your separate brake pedal or thumb throttle.
  

Make sure both connectors are plugged in properly before continuing.

Step 2 — Connect to Your VESC

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

Step 3 — Enter Input Setup

1. Go to the Start tab.
   
2. Tap Setup Input.
   
3. When prompted, choose ADC Input.
   

You should now see two bars on the screen:

• Top Bar → ADC1 (Throttle Pedal)
  
• Bottom Bar → ADC2 (Regen Brake Throttle)
  

Step 4 — Calibrate Both Throttles

1. Press your main throttle a few times → release it.
   
2. Press your regen brake throttle a few times → release it.
   
3. Tap Apply & Write.
   
4. Press both throttles again to confirm the bars fill their full range.
   
5. Tap Next.
   

Step 5 — Set Control Type for Two-Throttle Operation

1. Change Control Type to:
   
   Current No Reverse Brake ADC2
   
   ADC1 = main throttle
   
   ADC2 = regen brake pedal / thumb throttle
   
2. Disable Safe Start.
   
3. Tap Write Configuration.
   
4. Tap Next.
   

Step 6 — Set Regen Braking Strength (Profiles Tab)

Regen braking force is controlled through motor scaling:

1. Scroll to the Profiles tab.
   
2. Tap Add Profile.
   
3. Set Motor Current Scale to 5–15% to start.
   Higher % = stronger regen braking
   
   Start low to avoid overly aggressive braking
   
4. Save the profile.
   
5. Tap Use Permanently so the regen profile stays active.
   

Step 7 — Verify Battery Regen Safety Limits

Battery Current Regen Max MUST be set correctly or you can damage your battery.

Go to:

Motor CFG → General (Current Mode)

Check:

• 
  Battery Current Regen Max = ~ -5A (safe for most packs)
