  • Lithium iron phosphate: this type of battery has better durability and longer lifespan than other types but has lower energy density.
  • Lithium nickel cobalt aluminum oxide: this type of battery has high energy density and long life but comes at a higher cost.

When choosing a battery for your device, consider the energy density, capacity, and cost of the battery.

The Bottom Line

Lipo batteries offer an excellent power source for a variety of devices. Understanding how they work and the different types available can help you choose the best one for your needs. Remember to always use caution when handling these batteries since mishandling them can lead to severe consequences.

Common Reasons Why Lipo Batteries Won’t Charge

Over-Discharging: The Silent Killer

Over-discharging a lipo battery is one of the most common reasons why your battery won’t charge. It is like slowly poisoning your precious power source to death.

Do you want to know what’s worse? The damage caused by over-discharging is irreversible!

Once you have over-discharged a cell, it will never hold a charge again. Good luck trying to revive your “dead” cell.

So, what is over-discharging anyway? Over-discharging occurs when you continue to use your lipo battery even when it’s almost empty.

This can cause the voltage of the cell(s) in question to drop below a safe level, resulting in permanent damage. Not only will this cause your battery to die prematurely, but it’s also incredibly dangerous!

Over-discharged cells are prone to swelling and overheating which leads to the risk of explosions. The best way to avoid over-discharging is by monitoring your lipo battery’s voltage level and stopping usage before it reaches an unsafe point.

You can use a low-voltage alarm that beeps once the voltage reaches its minimum safe limit or go old school and simply check the voltage with a multimeter. Don’t forget that prevention is always better than cure!

Overcharging: A Recipe for Disaster

Another common reason why lipo batteries won’t charge is overcharging them. Just like over-discharging, this can lead to permanent damage and make them dangerous for future use.

Overcharging happens when the charger continues charging after the battery has reached its maximum capacity, causing excessive heat build-up and instability inside each cell leading in turn to swelling cells that may explode at any time. To avoid this potential hazard, use a charger that is specifically designed for lipo batteries and has an automatic shut-off system to prevent overcharging.

Don’t try to skimp on your charging equipment or use chargers intended for other battery types. You could easily burn down your home by being careless!

When in doubt, check the voltage level of your battery before and after charging. If the voltage increased past the maximum safe limit, then you are overcharging it!

Damaged Cells: The Hidden Culprit

Damaged cells are often overlooked as a possible reason why a lipo battery won’t charge. It’s easy to assume that if all the cells look good and balanced, then there must be no underlying issues. But here’s the thing: even a single damaged cell can cause problems with charging.

A damaged cell will have lower capacity than its still-working counterparts and will struggle to hold a charge compared to them. How do you know if your lipo battery has damaged cells?

You can look out for signs such as swelling or discoloration on individual cells or even check their voltage levels manually using a multimeter. The best way to prevent this problem is by handling your lipo battery gently and keeping it away from sharp objects or other items that could puncture it.

Faulty Charger or Charging Cable: The Scapegoat?

A faulty charger is also one of the main reasons why your lipo battery won’t charge. Sometimes we might blame our batteries when really we should be pointing fingers at our charger!

It’s not uncommon for chargers to malfunction especially with cheaper brands that don’t follow safety standards- so if you’re planning on buying one make sure you do some research first! Also poor-quality cables can be problematic since they carry electricity directly into your device; so again, always buy high-quality cables that have been tested and approved.

Before freaking out about your battery not charging, try swapping the charging cable or charger. If it still won’t charge, then you can start troubleshooting for other issues.


There are several reasons why your lipo battery might not charge. Over-discharging and overcharging are the most common culprits which can lead to permanent damage or explosions! Damaged cells and faulty chargers also contribute to this problem.

Remember that the best way to prevent charging issues with your lipo battery is by taking care of it properly and using high-quality equipment. Don’t put yourself at risk just to save a few dollars on cheap chargers because you could end up losing a lot more than you thought!

Over-Discharging: The Silent Killer

If you’re a frequent user of lipo batteries, you may have experienced the frustration of finding that your lipo battery won’t charge. Many factors can contribute to this issue, but one that is particularly insidious and often overlooked is over-discharging.

Over-discharging occurs when you drain your lipo battery below its recommended minimum voltage level. This can cause irreversible damage to the battery’s cells and render it unusable.

It’s like sucking all the life out of a person until they’re nothing more than a husk. The problem with over-discharging is that it can happen so easily, especially if you’re not paying attention to your battery’s voltage levels.

Maybe you were too distracted by the fantastic performance of your drone or RC vehicle to notice that your battery was running low, or perhaps you thought it would be okay to push the limits just a little bit further. But in doing so, you put your beloved lipo battery at risk.

How Over-Discharging Happens

There are many ways in which over-discharging can occur. One common scenario is when the user fails to monitor their lipo battery’s voltage levels while using their device and continues using it past its recommended minimum voltage level. Another scenario could be leaving the lipo battery connected for an extended period of time without use or maintenance.

In any case, over-discharging results in damage to the internal structure of a lipo cell. Once this happens, there’s no going back – it’s like giving someone an incurable disease and watching them slowly waste away.

Preventing Over-Discharge Damage

The best way to prevent over-discharge damage is always monitoring your lipo batteries during usage and maintaining their voltage levels. Depending on the device, there may be automatic cutoff features that can prevent over-discharge. However, some of those features aren’t always reliable and cause additional problems.

For the best protection against over-discharge damage, you should use a lipo battery monitor or alarm. These devices will alert you when your battery’s voltage level drops to a certain point, giving you ample time to shut down your device and recharge the battery.

Another way to prevent over-discharge damage is simply not to push your lipo battery past its limits. Always be mindful of how much power your device is using and how long it’s been running.

If you know that your lipo battery has a limited capacity, plan accordingly and don’t overtax it. In this way, you can ensure that your lipo batteries last as long as possible without suffering any undue harm.

Over-discharging may seem like a minor issue compared to other potential causes for why won’t my lipo battery charge; however, its effects are far-reaching and permanent once they happen. If left unchecked or untreated for too long, it can lead to irreversible damage to the cells of the lipo battery until it becomes useless.

Overcharging: A Recipe for Disaster

The Dangers of Overcharging

If you’re a lipo battery user, you’ve probably heard about the dangers of overcharging. But do you really understand just how dangerous it can be?

Let me tell you: overcharging is a recipe for disaster. When you overcharge your lipo battery, it can lead to swelling and, in some cases, even fire or explosion.

That’s right – an overcharged lipo battery can actually explode! And if that happens, it could cause serious injury or even death.

How Overcharging Occurs

So how does overcharging happen? It’s simple really – when you charge your lipo battery beyond its maximum capacity, it starts to heat up.

And as the temperature rises, the internal components of the battery start to break down. This can cause the electrolyte inside the battery to decompose and produce gas – which leads to swelling and potentially even an explosion.

The Importance of a Good Charger

One way to avoid overcharging your lipo battery is by using a good charger. A high-quality charger will have safety features built in that prevent overcharging by monitoring the voltage and current levels during charging.

But be warned: not all chargers are created equal! If you use a cheap or low-quality charger, it may not have these safety features – which means your lipo battery could be at risk.

Don’t Ignore the Warning Signs

Another way to avoid overcharging is by paying attention to warning signs. If your lipo battery starts getting hot during charging or if it swells up, stop charging immediately!

These are signs that your battery may be experiencing an issue with overcharging. Continuing to charge in this situation could lead to disastrous consequences.

The Bottom Line

Overcharging is a serious issue that can cause harm to you and those around you. If you use lipo batteries, it’s important to understand the risks of overcharging and take steps to prevent it from happening.

Use a high-quality charger with safety features, pay attention to warning signs, and don’t take any chances. Your safety and the safety of others depend on it!

Damaged Cells: The Hidden Culprit

When it comes to lipo batteries not charging, the first thing that comes to mind is often overcharging or over-discharging. However, damaged cells are a hidden culprit that is frequently overlooked.

Even if your lipo battery seems to be in good shape physically, one or more of its cells may have been damaged by repeated misuse or abuse. The most common cause of cell damage is over-discharging.

When you run your lipo battery down too low, one or more of its cells can drop below the minimum voltage needed for proper operation. If this happens repeatedly, those cells can become permanently damaged and unable to hold a charge.

Another way that cells can become damaged is from overcharging. When a lipo battery is charged too quickly or with too much current, the cells can heat up and become stressed.

Over time, this stress can damage the internal structure of the cell and reduce its ability to hold a charge. In some cases, physical damage to the battery can also cause cell damage.

If you drop your lipo battery or crush it in some way, this can cause internal damage to one or more of its cells. You may not see any external signs of damage on the battery casing, but internally there may be serious issues that prevent it from holding a charge.

What Causes Cell Damage?

There are many things that can cause cell damage in your lipo battery:

  • Over-discharging
  • Overcharging
  • Physical damage
  • Prolonged exposure to high temperatures
  • Poor quality charging equipment

If you suspect that one or more of your lipo battery’s cells have been damaged, there are several ways to test them. You can use a voltmeter to check the voltage of each cell individually and compare it to the voltage of the other cells.

If there is a significant difference in voltage between cells, this could indicate that one or more of them is damaged. Another test you can perform is called an internal resistance test.

This measures the resistance of each cell and can give you an idea of its overall health. A healthy lipo battery should have cells with similar internal resistances.


Damaged cells are a hidden culprit that can cause your lipo battery to stop holding a charge. If you’ve tried all the usual solutions like checking your charger and making sure your battery isn’t over-discharged, it’s time to take a closer look at your battery’s cells.

While it may be tempting to keep using a damaged lipo battery, doing so could lead to permanent damage or even an explosion in extreme cases. Always handle your lipo batteries with care and be on the lookout for signs of damage or wear.
