LiPo batteries and RC cars go hand in hand. In fact, most drones and RC vehicles use LiPo batteries to power themselves. However, as you might be aware, they tend to run the risk of catching fire and exploding. To mitigate the risk and eliminate the hazard, you can use fireproof battery bags.
But, what exactly are they? And how to choose one? Well, we have extensively researched and reviewed some of the best LiPo battery bags in the market. Out of these the following five really stood head and shoulders above others.
What are LIPO Charging Bags?
You might wonder why exactly do LiPo’s require charging bags. While you can use any Lithium-ion charger for Li-Po batteries, it can be dangerous. Li-Po batteries run the risk of fire and explosions while they are charging.
The main concern is due to faulty charging or poor craftsmanship. For example, if you do not charge the battery at the proper voltage, it has a higher chance of exploding.
A charging bag is basically a flameproof and explosion proof bag that keeps you safe while your LiPo battery charges. However, we highly recommend that you use it for storing and transporting LiPo batteries as well.
These bags usually include materials that are flame retardant or fireproof. This way even if your battery catches fire or explodes, you can rest assured that you will remain safe. This is because these materials block the fire and prevent it from escaping.
Why Are They Necessary?
As we already explained, LiPo batteries are quite volatile and they can explode in a number of occasions. These bags protect you in every way by isolating the incident as much as possible.
LiPo batteries need to be handled extremely carefully otherwise, you run the risk of a fire hazard. While charging, they tend to be the most dangerous. A high-quality Safety Bag ensures that your battery remains safe and any fires are successfully averted.
Carrying LiPo batteries by hand can be quite dangerous. In fact, traveling with them in a car can lead to fire due to the internal heat. The heat blocking materials of the LiPo bag prevent the battery from ever catching fire. Many airlines require you to travel with these batteries in a bag.
Storing these batteries outside might also result in accumulated heat. Thus, it is best to use a high-quality storage bag that blocks all heat out.

How to Find the Best LIPO Charging Bag
There’s a wide variety of charging bags present in the market. How do you choose the one that’s best suited for an RC car enthusiast like you? The following major factors are crucial to consider.
One of the most important factors to consider is the size. Ensure that the size of the bag is sufficient to store and charge the batteries you have. For example, if you have many RC cars and LiPo batteries, then going for a larger one might be more suitable.
On the other hand, if you have only a handful and you do not plan on expanding them, then a smaller one will suffice. Otherwise, you could end up with a large bag that is too hard for you to carry.
Another crucial factor is durability. You need to ensure that the materials are durable. Mostly, the material used to retard the flames is fiberglass nylon.
Other materials are used as an exterior lining on top of the fiberglass nylon so that it isn’t irritating. These can include silicon and aluminum.
Most bags include a double zipper that might be made out of plastic. The plastic construction can easily melt due to high temperatures. If the zippers melt, there’s a high chance that flames may escape. Also, when you charge the batteries, there might be an open space through which you draw out the wires. This may also lead to the flames escaping the bag.
To ensure proper security of the bag, look for separate ports for charging and Velcro straps over the zipper. Thus, even if the zipper fails, you still have another layer of protection.
Minimizing Risks From LIPO Batteries
While it’s true that LiPo batteries can be a huge hazard, you can easily mitigate these risks by following the proper procedures for charging.
Here are a few tips to help ensure safety:
- Read all the instruction leaflets included with the battery. If it doesn’t come with one, check the manufacturer’s websites or check what users are saying in their reviews.
- Don’t forget to test your charger out. Also, read all instructions related to it.
- Check the manual for the accurate charge rate and set it at that. In addition, set the correct polarity.
- Put the battery inside the safe bag for charging.
- Attach all the charging leads to the battery.
- Remember to place the bag on an insulated surface that is dry.
- If the bag contains a separate port, put the leads through there.
- Close the charging port with the Velcro. Also, close the zipper ensuring there is no space for any flame to escape.
- Start charging.
- Never buy used LiPo batteries as you don’t know how the previous owner might have used them.
