Hey there! We’ve received a few questions about why their DM Mid-Drive Motor’s display’s battery display doesn’t always match the actual battery charge. 

For example, you might see your battery is fully charged (100%), but the display only shows 75%, so we wanted to share a quick tip to help you get the best ride possible.

What Should You Do?

To get the most precise battery reading possible:

  1. Check Your Battery Specs: Look at your battery’s voltage and capacity information (often found on the battery label or in its manual).

  2. Manually Adjust Motor Settings: Use our reference table below to set the correct voltage parameters in your motor’s display settings. This helps the display better match your battery’s actual usage.

Even after adjustment, the display may not be 100% accurate, but it will be much closer to your real battery status.

 

Why Does This Happen?

No Common Communication Protocol: Our DM Mid-Drive Motors are designed to work with a wide range of batteries on the market. However, there isn’t a universal communication protocol between the motor and every battery brand.

This means the motor’s display can’t always “talk” directly to your battery to get a perfectly accurate reading.
