How to Reset an Electric-bike Battery – Complete Guide 2024

The battery is an essential and expensive part of an electric bike after the engine. Resetting it will be costly. Knowing a little about battery resetting and maintenance is essential. It can save effort and. This article will teach us how to reset an electric bike battery with BMS.

How to Reset an Electric-bike Battery

How to Reset an Electric-bike Battery: Step By Step

There are generally two methods for resetting an electric bike battery: externally or internally. You can try whichever one makes you feel the most at ease.

A. Reset An Electric Bike Battery Externally

Let’s start with the external method and some easy steps are following:

Step 1: Collect the Materials

Collect all necessary tools and equipment to reset an electric bike battery. These are the following:

  • A. a voltmeter or multimeter,
  • B. Wire cutters,
  • C. A soldering iron and
  • D. Safety gloves.

Step 2: Get Materials

Now, Collect the necessary materials. These include electrical tape, red and black wires, and a DC Barrel Jack Receptacle.

Step 3: Create the Adapter

To start with, put on your safety gloves. You’ll be working with a soldering kit. And, later, live electricity, so keep yourself safe at all times.

The DC barrel jack and two wires will make up your adapter. Attach a red cable to the positive terminal of the battery jack. And a black wire to the negative terminal using the soldering kit.

You can also use electrical tape. It helps to hold everything together and cover any exposed parts.

Step 4: Connect the Electric Bike Battery Charger to the Adapter.

It must ensure the adapter’s wires are not touching. Verify the correct connections using a voltmeter. The red wire connects to the red pin of the adapter. And the black wire to the black plug, yielding a positive voltmeter reading. The cables connector the incorrect terminals if the task is harmful.

Step 5: Connect the Adapter Wires to the Correct Terminals

After that, connect the adapter wires to the appropriate discharge port terminals. The positive terminal connects to the red wire of the jack. The negative terminal to the black wire for resetting an electric bike battery.

Step 6: BMS Reset an Electric Bike Battery

Connect the adapter to the discharge port of the battery next. If you look closely at the port, you’ll notice it has indicators indicating where each wire plugged in. The red wire connects with the positive terminal of the jack. Also, the black wire connects to the negative terminal of the jack.

If everything is working correctly, the charger’s light turns red. Holding the wires in place for 15 seconds should cause the BMS to reset itself.

After that, disconnect the battery charger and remove the adapter. You can now verify the BMS. It allows the battery to charge and discharge usually.

B. Reset An Electric Bike Battery Internally

As you can see, resetting the BMS of an electric bike battery externally necessitates. It uses live electricity, custom wiring, and a DC adapter. Suppose you are unsure or uncomfortable working in this manner. Many people prefer the second method for resetting an electric bike battery. Because it is much simpler. Here to reset an electric bike internally, are the following:

Step 1: Open the battery

To begin, use your screwdrivers to remove the battery’s top cap. A few screws in the top hat are typically held in place.

This will allow you access to the battery’s interior. It will find the BMS, battery cells, and the wires that connect everything.

Step 2: Pull The BMS Chip Out

Deep inside the battery case, the BMS keeps battery cells safe. So, to make it easier to work on, gently slide everything out by a small amount. You don’t need to remove everything from the battery case

Remember. Don’t pull too hard on any wires or cells you see. Require a gentle push.

Step 3: Resetting the BMS of Electric Bike Battery

Please pay close attention to the BMS, and it connects to several wires via a harness. Take the following steps:

  1. Unplug the wire harness from the BMS.
  2. Make sure to plug in your charger.
  3. Connect the wire harness to the BMS once more.
  4. Reseal all components within the battery case in the same manner as before.

Finally, test the battery’s functionality to ensure it has successfully reset. Connect it to the charger and return it to the e-bike to confirm. It can charge and discharge.

What is a Battery Management System (BMS) of an Electric Bike?

In lithium-ion batteries, a microcontroller regulates charging and overcharging. These devices are also known as Battery Management Systems (BMS).

Lithium-ion batteries will often recover independently after being fully depleted and recharged. If not, resetting is a suitable option. The main functions are the following:

  1. Protection
  2. State of Charge (SOC) Calculation
  3. Health and Safety Monitoring
  4. Cell Balancing
  5. Temperature Monitoring and Control
  6. Communication and Data Sharing
  7. Error Codes and Diagnostic Information

How to Maintaining E-bike Batteries?

Proper maintenance practices are essential for electric bike batteries. It helps to ensure the longevity and optimal performance of your bike battery.

A. Regular Charging

Charge your e-bike battery regularly, even if you do not use it for a long time. This preserves the battery’s capacity. Keep it from fully discharging, which can shorten its lifespan.

B. Battery Storage

Store your bike battery for an extended amount of time. Make sure it is fully charged. Keep it cool and dry. Please keep it safe, far from direct sunlight and extreme temperatures. Check the battery’s charge level regularly and recharge if necessary.

C. Battery Cleaning and Checking

Clean your electric bike battery regularly and remove any dirt or debris. Check out the battery for physical damage, such as cracks or bulges. If you notice any irregularities, seek the advice of a professional.

Final word

Resetting an electric bike battery can be a quick and easy way to improve battery performance. Ensure the electric bike battery provides a reliable power source. The two most common methods are used for reset an electric bike battery. The ability to skill reset an e-bike. It would save you a lot of time (and money). If you ever had a battery refuse to charge or discharge properly.



I am working in a restaurant. One of the responsibilities is to monitor the Kitchen Appliances’ performance and inform the maintenance department. Sometimes, I work closely with the maintenance team.  I have gained some knowledge of kitchen appliances from there and want to share it with you. I have a passion for explaining my understanding simply.
