Download SuperpowerBMS app below to monitor and update your battery. Follow along with the instructional Youtube video to correctly update your RCR 80V to the latest and greatest battery updates.

Download both the App and latest firmware to update your RCR 80V. Follow along with the instructional Youtube video to correctly update your RCR 80V to the latest and greatest controller firmware. We will periodically update the bike to further improve the experience and even offer firmware updates that are optional settings adjustments for specific riding styles. So keep a look out for updates and only install ONYX approved firmware.

Hello Riders,

We want to address the performance of the thermal management system on your 80V bike, particularly during aggressive riding. If you push the bike hard, you will experience the system engaging to regulate temperature. Please be assured that this is a normal and intentional safety feature designed to protect the motor and battery; there is nothing wrong with your bike.

Our team is actively developing a firmware update to refine this experience. We have heard your feedback and agree that the current power reduction can feel abrupt. The goal of the update is to create a smoother, less intrusive system by implementing a more gradual power taper and potentially raising the activation threshold.
We are aiming to release this firmware update after we return from the Electrify Expo in NYC. It will be available for download on our website.

In the meantime, here are some helpful tips for managing heat and optimizing your ride with the current firmware:

Understand the Triggers: Continuous use of Hyper or Sport mode, especially while accelerating quickly or climbing hills, will raise system temperatures and engage the thermal protection. The duration of high-power riding will vary depending on the terrain and your riding style.

 Managing Power Reduction: When the system engages, you may notice a warning and a reduction in power. If you temporarily push through this, you can maintain higher speeds, but the system will fully re-engage once you release the throttle.

Recommended Technique: When the thermal management engages, we recommend switching to Normal mode for a few minutes. This allows the system to cool efficiently, after which you can typically return to Sport or Hyper mode for another high-performance run.

Use Hyper Mode Strategically: The 80V platform is significantly more powerful than our 72V line, and as a result, it generates heat more quickly under intense use. Hyper Mode is designed for short bursts of maximum performance and will heat the system rapidly. Using it moderately will extend your available time in all modes before you see the warning messages. 

This behavior is consistent with high-performance electric vehicles, including our 72V models when tuned for maximum output (e.g., "Sikko Mode"), which also experiences "heat lag" after demanding use.

We are committed to continuously improving your experience, and this upcoming firmware update is a top priority. We appreciate the fantastic feedback many of you have shared and look forward to making your ride even better.

Thank you for your support.

The new 45Ah ONYX batteries use QS8 discharge connectors.
If your bike still uses the older red Anderson SB50-style connector, you’ll need to swap out your main battery cable to be QS8-compatible.

👉 Buy the ONYX QS8 Main Battery Cable

⚠️ Note: Anderson-style battery leads are not compatible with the new 45Ah ONYX batteries.

Step-by-Step Installation

1. Remove the Righthand Side Panel

• To access one of the five panel screws, you'll need to remove the seat.
  
• If you do not have a rear rack installed, you can instead loosen the four seat nuts and slide the seat backward and out of the way.

2. Unplug & Remove the Battery

• Disconnect your battery and remove it from the tray.

3. Remove the Existing Battery Cable

• Use a 14mm wrench to remove the two terminal nuts securing the existing Anderson battery lead.

Remove the old Anderson cable completely — it will no longer be used.

4. Install the QS8 Battery Cable

• Route the new QS8 connector through the designated hole (see diagram/photo).

❌ Do not route it through the hole inside the battery tray — this will interfere with battery placement.

5. Connect to Terminal Posts

• Attach the new positive (red) and negative (black) ring terminals to the matching posts.
  
• These terminals should sit:
  
• On top of the battery/controller lugs
  
• Underneath the terminal post nuts
  

✅ Color Match Reminder:

• Red → Yellow/Positive
• Black → Black/Negative

6. Secure the Installation

• Tighten the nuts using a 14mm wrench.
• Reattach the righthand side panel.
• Reinstall or slide the seat back into position and tighten seat nuts if loosened.

Step 1: Identify Your Battery

• 41Ah Battery
  → Requires the “Xiaoxiang BMS” app. 
  → Available on iOS and Android phone or tablet
         iOS |  Android
  
• 45Ah Battery
  → Requires the “Superpower BMS” app. iOS | Android
  → Available on iOS and Android phone or tablet
         iOS |  Android
  

Step 2: Connect to the BMS

1. Download the correct app based on your battery (see above).
   
2. Enable Bluetooth on your device.
   
3. Open the app and begin scanning for available BMS devices.
   

Device ID Prefixes:

• 41Ah (Xiaoxiang BMS):
  Look for a device ID that starts with HD or EK
  
• 45Ah (Superpower BMS):
  Look for a device ID that starts with CLY
  

Step 3: Review Battery Health

Once connected, you will see detailed battery metrics, including:

• State of Charge
  
• Cell Group Voltage
  
• Cell Balance Information
  

👉 Important:
The voltage difference between cell groups should ideally be no more than 0.1–0.15V.
If the battery is significantly out of balance, it may:

• Fail to reach full charge
  
• Cut out during rides
  
• Indicate a deeper issue with the battery or BMS
