It has been a long time since the pandemic that e-bikes are the solution to avoiding traffic congestion, pollution, and optimizing your fitness level. There’s no doubt that e-bikes have the potential to transform the transportation sector. Unfortunately, the surge in demand for e-bikes has led to an increase in the manufacturing of low-cost e-bikes comprising poor-quality components.

Consequently, using such e-bike components can be hazardous to the rider. One such instance is that of fire hazard from e-bike batteries. But remember, not all e-bike batteries are dangerous.

So, what causes e-bike battery fire and how can it be prevented? We’ll discuss all of these in our blog.

Why Do E-Bike Battery Fires Occur?

The most common type of battery in e-bikes is a lithium-ion battery. Nevertheless, they’re more prone to exploding if the batteries are made through an inferior-quality manufacturing process.

In other words, e-bike battery manufacturers can use cheap materials or cut corners when making an e-bike battery; the risk of defects increases and can cause the cells to expand, bulge, and burst.

Another reason for e-bike battery fire hazard is using non-brand chargers. Many high-performance e-bikes are integrated with a battery management system (BMS). This feature regulates excessive discharging or overcharging of the battery.

Cheap, non-brand chargers do not have BMS and in the absence of it, the battery can overcharge and explode at times. Or it can discharge to such a high extent that recharging the battery completely can be difficult.

Most e-bikes use a lithium-ion battery and if it catches fire, putting it out is quite challenging due to chemical reactions. Hence, purchasing an e-bike battery and charger only from the company where you bought the e-bike is always recommended.

Important Tips to Prevent E-Bike Battery Fire

Lithium-ion batteries are efficient but unfortunately, if they catch fire, it spreads quickly and as I mentioned, dousing the fire is difficult. But don’t worry! I will walk you through the essential safety tips below to avoid e-bike battery fire risks.

  1. Buy Charger from a Reputable Brand

You may be tempted to save money by buying an off-brand charger as it costs much less than the branded one. The problem is that, often, manufacturers create cheap chargers that lack advanced features or don’t undergo any testing. This is done to cut corners.

Consequently, using such products increases the risk of a fire hazard. Thus, buying from a reputable and reliable store or website is a wise decision, especially of the same brand that your e-bike is. These chargers are designed with safety features to prevent overcharging and overheating.

  1. Be Careful When Charging E-bike batteries have a greater risk of catching fire when charged. To prevent this from happening, avoid charging the battery overnight, as doing so will overcharge it and cause the battery to explode. Besides, always follow the manufacturer’s instructions that came with the e-bike for charging. Use the charger given with your e-bike model and not just any charger for other devices.
  1. Proper Storage

Store your e-bike in a cool and dry place when it is not used. This will help keep the e-bike battery safe from any damage caused by exposure to moisture or heat. If the battery is detachable, avoid leaving it in your car, as high temperatures can increase the risk of battery fires. Storing your e-bike near an exit or in the hallway is a bad idea too. Instead, always look out for a parking shade or garage.

  1. Replace the E-Bike Battery If It Is Damaged

Notice any signs of damage on your e-bike battery? Is your e-bike battery degraded? Consider getting a replacement. Inspect your e-bike battery regularly for any signs of physical damage. If you notice cracks or dents, replace the battery immediately.

  1. Reach Out to the Manufacturer If You’re Having E-Bike Battery Issues

Rather than trying to troubleshoot any e-bike battery problem yourself, always contact the manufacturer. Take clear pictures and videos to illustrate the problem precisely and share them with the support team.

What to Do If Your E-Bike Battery Catches Fire?

If you notice sparks, smoke, or if the e-bike battery is swelling, avoid using the e-bike battery. As e-bike battery fires are tough to put out, it is advisable to inform the fire brigade or police. While waiting for the fire brigade or police to arrive, remember these points:

  • Evacuate the area immediately
  • Do not inhale the smoke as it is poisonous
  • Turn off the power supply of the building to prevent short circuit
  • Do not pour water over the battery as lithium reacts to water explosively


Can e-bike battery fires be deadly?

E-bike battery fires can be hazardous and while they are not typically deadly, they can cause injuries and significant property damage.

Are all e-bike batteries the same?

No, e-bike batteries can vary in terms of quality and safety features. It’s essential to select a reputable manufacturer and charger.

What should I do if my e-bike battery overheats?

If you notice your e-bike battery overheating, disconnect it from the charger and place it in a safe, fire-resistant area.

Can I repair a damaged e-bike battery?

It’s not recommended to repair a damaged e-bike battery. Instead, replace it with a new one to ensure safety.
