Dealing with Puffed Lipo Batteries: Causes and Solutions

Dealing with Puffed Lipo Batteries: Causes and Solutions

Are you tired of your Lipo batteries puffing up and losing their power prematurely? Don’t worry, you’re not alone! Puffed Lipo batteries are a common issue among RC hobbyists, drone pilots, and other electronic enthusiasts. But what causes this problem and how can you fix it? In this article, we’ll explore the reasons behind puffed Lipo batteries and provide practical solutions to help prolong the lifespan of your battery packs. So let’s dive in!

What are Puffed Lipo Batteries?

Lipo batteries are rechargeable and lightweight power sources used in various electronic devices such as drones, RC cars, planes, and boats. When a Lipo battery starts to puff up or swell, it becomes unable to provide the required amount of voltage and current consistently.

The swelling occurs because of gas buildup inside the electrolyte solution or polymer pouch. This can happen due to several reasons like overcharging, overheating during use or charging, physical damage to the battery pack, and prolonged storage at high temperatures.

If you spot any bulging bumps on your Lipo batteries while using them or storing them for future use; it’s time to take immediate action before they become unusable. The longer you leave them untreated, the more dangerous they become – risking explosion or fire hazards.

Puffed Lipo batteries are unsafe and unreliable energy sources that can cause severe harm if left unattended. It is essential to understand their causes so that we can prevent these issues from occurring in our devices.

Causes of Puffed Lipo Batteries

When it comes to understanding the causes of puffed LiPo batteries, it’s essential to start with the basics. A LiPo battery is made up of cells that contain lithium ions and an electrolyte solution. When charged and discharged properly, these batteries operate safely and efficiently. However, if something goes wrong during this process, such as overcharging or discharging too quickly, it can cause a buildup of gas inside the cell which leads to puffing.

One common cause of puffed LiPo batteries is overcharging. This occurs when a battery is left on charge for too long or at too high a voltage level. Overcharging causes an excess amount of energy to be stored in the battery cells which can lead to overheating and swelling.

Another cause of puffed batteries is discharging them below their recommended levels repeatedly. If you discharge your LiPo battery down below 3V per cell several times in a row without recharging it fully each time, then there’s a chance that you’ll end up with some puffiness.

Using improper charging equipment or not following manufacturer recommendations for storage and handling can also result in puffed LiPo batteries.

Knowing what causes your LiPo batteries to puff will help you take appropriate measures to avoid them from happening again in future use cases!

Solutions to Puffed Lipo Batteries

Fortunately, there are some solutions to dealing with puffed Lipo batteries. First and foremost, it is essential to dispose of the battery safely. You can do this by contacting your local waste disposal authority or recycling center for advice on how best to get rid of it.

If you have a puffed Lipo battery that hasn’t exploded, you may be able to salvage it by following these steps. Start by discharging the battery completely using a low voltage cut-off device or discharge tray. Once fully discharged, remove the heat-shrink wrap and inspect the cells for any visible damage.

If there isn’t any physical damage present, try charging each cell individually using a dedicated LiPo charger with an accurate balance function. Charge each cell slowly at no more than 1C (one times its capacity) until they reach their nominal voltage.

Once all cells are charged correctly, reassemble them into your pack and monitor their performance during use closely. It’s also worth noting that once a lipo has puffed up; it has lost much of its original capacity and will not provide adequate power as before.

While fixing puffed Lipo batteries is possible in some cases; prevention is always better than cure when dealing with lithium polymer chemistry remember always handle your LiPo batteries carefully and avoid overcharging or puncturing them at all costs!

How to Prevent Puffed Lipo Batteries

Preventing puffed lipo batteries is crucial to ensure the safety and longevity of your battery. Here are some tips to help prevent puffed lipo batteries:

1. Proper Charging: Always charge your battery with a charger that is designed for that specific type of battery, and make sure to follow the manufacturer’s instructions for charging voltage and current.

2. Storage: When storing your battery, keep it in a cool, dry place away from direct sunlight or any heat sources. Avoid leaving it fully charged or completely discharged for long periods as this can cause damage.

3. Handling: Be careful when handling your battery; always use protective gear such as gloves, goggles, and aprons when handling a damaged or swollen lithium polymer cell.

4. Balance Charging: Use balance charging where possible rather than fast charging so that all the cells get balanced properly after every cycle.

5. Quality Batteries: Invest in high-quality batteries from reputable manufacturers who carry out proper testing before selling their products.

By following these simple steps you can successfully prevent puffed lipo batteries which will protect both yourself and others around you who may be affected by an exploding lithium cell due to improper care!


Puffed lipo batteries are a common problem that can be caused by various factors such as overcharging, overheating, or physical damage. However, with the right solutions and preventive measures in place, you can minimize the risk of experiencing this issue.

When dealing with puffed lipo batteries, it is important to handle them with caution and follow all safety guidelines. Never attempt to use or charge a damaged battery as it could cause serious harm or even start a fire.

If you do encounter a puffed battery, dispose of it properly and invest in high-quality replacements from reputable manufacturers. By taking these steps, you will ensure the longevity and reliability of your devices while keeping yourself safe from potential hazards associated with faulty lipo batteries.
