This article is dedicated to showing how to test the voltage of the battery by using a voltmeter.

When you have encountered the following situation, we might need you to test the battery's voltage for us to identify the problem:
-Battery cannot be charged.
-Range is reducing.
-Battery life is reducing.

Prepare:

To test your e-bike battery, the only tool you’ll need is called a multimeter.
A multimeter is a simple electrical measuring instrument that’s cheap and easy to get. You can find them on Amazon.





Execute:

• Turn on your multimeter and set it to DC Mode (200VDC)
  
  
  
  
  
  
• Put the negative probe (the black one) on the battery charging port 1 and put the positive probe (the red one) on battery charging port 3 (see picture)
  
  
  
  
  
  
  
  
  
• See reading on the multimeter, if the battery's voltage is 48-54V, then it is normal, if not, the charging port might not be working.
  
  
• Check the voltage of the connector on the battery, if the battery's voltage is 40-54V, then the battery is normal, if not, the battery might not be working.
  
  
  
  
• If the voltage of the battery is normal, please test the voltage of the charger, as in this case the charger might have an issue:
