If you’re involved in the world of RC, you probably know how important it is to have a good LiPo battery.
That being said, you might be unsure of what the best LiPo battery is, and whether it fits your needs.
We created a list of high quality LiPo batteries worth considering, and also go into detail about connectors, taking care of the LiPo battery, and more. Let’s get started!

1. What is a lipo battery?
Lithium Polymer batteries (LiPo for short) are a newer type of rechargeable battery used in RC vehicles such as trucks, planes, and crawlers.
If you’re in a hobby that involves radio control, you most likely have come across LiPo at some point or another.
But why are these batteries so popular?
LiPo batteries offer a variety of benefits that batteries such as Nickel-Metal Hydride (NiMH) does not. Below you will find some of the pros and cons of LiPo batteries.
Light in weight, and can be modified into a variety of shapes and sizes
Have large capacities, which means the batteries have the ability to hold much more power
Have high discharge rates.
Have a shorter lifespan than NiMH batteries
Can catch fire if improperly treated
Requires more of an investment in keeping it functioning properly
As you can see, LiPo batteries offer numerous advantages in powering RC vehicles. However, it’s important to make sure you understand all of the jargon used in describing the battery before you purchase it.
2. Understanding battery terminology
Voltage – When looking at the markings on a battery, you’ll see a number followed by the letter V. That number describes the voltage of the the battery. A LiPo cell has a nominal voltage of 3.7V. Nominal voltage indicates the resting voltage of the battery.
If you’re wondering why your battery has a number like 7.4V, that just means there are two cells in the battery.
To know the number of cells in the battery, find a number on the battery that is followed by an S. For example, “2S” means there are two cells in a S(eries), “3S” , means there are three cells, and so forth.
Capacity – The capacity of a LiPo battery, which is measured in milliamp hours (mAh), is the maximum amount of power the battery can hold. The bigger the capacity is, the longer it will be able to provide power.
Maximum Charge Rate – The maximum charge rate indicates the maximum current you can charge the battery safely.
Discharge Rate – The discharge rate of a battery is essentially how fast a battery can be discharged without damaging the battery.
3. Taking proper care of your LiPo battery
When charging a LiPo, make sure you always use a charger that is LiPo compatible. If you don’t, you risk the chance of damaging the battery and reducing its lifespan.
When storing your LiPo battery, make sure you leave it in a cool area. Also make sure the battery isn’t fully charged when you’re done using it. If you store it when it’s fully charged, the cell matrix will likely degrade.
You always want to be around a LiPo battery that’s charging. If something were to happen (such as a battery exploding into flames), you need to be in the area so that you can take action.
4. LiPo safe charging and storage bags
If you want to be extra careful when storing and charging your LiPo battery, I would recommend getting a battery safe guard pack.
Trust me when I say that it’s better to pay a few bucks to prevent a fire, than a lot to repair the damage from a fire.
My recommendation for a good battery pack is the HobbyTiger Fire Retardant RC LiPo Battery Charging Bag pictured below.
The bag weighs about 5 ounces, and the dimensions are 8.46 inches x 6.1 inches x 4.53 inches. It’s made with fire retardant fiberglass and woven fabric.
The main reason I recommend this bag is because there is proof that this bag functions the way it’s supposed to. Check out these reviews here and see for yourself.
5. LiPo battery disposal
When it’s time to get rid of your battery, there are certain steps you need to take to minimize any risk.
- Discharge the battery – You want to safely discharge the battery as far down as possible. Many LiPo chargers have a discharge feature you can use in order to discharge safely.
- Create a salt water solution to put the battery in – Saltwater is useful for disposing a battery since it further discharges the battery. Just mix some warm water and salt together and fully submerge he battery into the solution. Keep adding salt to the solution until the salt stops dissolving. The battery should be in the water for about a day.
- Check the battery voltage – The steps above should (hopefully) ensure the LiPo’s voltage is 0V. If it’s not at 0V, repeat step 2 until it does.
- Throw the battery in the trash – The nice thing about LiPo batteries is that they won’t harm the environment. Once you bring the battery voltage to 0, you can just throw it out.
6. Types of Connectors
Different batteries have different connectors, so it’s important to understand how the connectors relate to one another.
Deans Connectors – Deans connectors are one of the most common connectors out there. They have existed for quite some time, and have been popular in the RC community.
If you’re dealing with Deans connectors for the first time, you may notice that soldering the connectors is a bit of a challenge. Make sure you’re using a soldering iron instead of a soldering gun because the soldering gun doesn’t really have the thermal mass to solder the connectors correctly.
XT-60 Connectors- Unlike the Deans connectors, the XT-60 connectors is much easier to solder. They are compact and small, and I haven’t seen many issues with these connectors.
EC3 Connectors – EC3 connectors are also easy to work with in terms of soldering. They may be more expensive, but they are rated for high amps, and are pretty easy to connect and disconnect.
7. Best LiPo batteries reviewed
What I love about Gens Ace is their ability to provide good LiPo batteries without incorporating the expensive cost. These batteries are a good choice for when you’re strapped for cash, but still want to enjoy using your RC vehicle.
The Gens Ace LiPo battery pack has a hard shell and a protective shrink wrap, so you won’t have to worry about it being easily punctured.
Gens Ace designed these batteries specifically for RC vehicles that are 1/8 – 1/10 in scale. If you have something in that range, like the Traxxas Rustler, then you won’t have to worry about whether or not you’ll have compatibility issues.
Unlike the other LiPo batteries mentioned on this list, these Floureon batteries come in pairs. The best part about Floureon is the 1 year warranty they are currently offering. That just goes to show how much faith they have in the quality of their products.
These batteries have a Dean style T connector. They last very long, and if something goes wrong, Floureon has great customer service.
Another great option is the Turnigy 2200mAh LiPo pack. These batteries are also very affordable, and have pretty good performance.
The connector plug for these batteries is the XT60 connector.
These batteries also have a 20C constant discharge rate with a 30C burst discharge rate.
The last battery on our list is the Gens Ace 5000mAh LiPo battery. The company also claims this battery has a long cycle life with at least 150 uses.
Something to take note of is the amount of power this LiPo battery provides. Depending on the quality of your RC vehicle, the tires might wear down much faster, and the motors may heat up much faster.
Even with these risks, it’s definitely pretty fun seeing vehicles run on these batteries.
Hopefully this guide helped you figure out which LiPo battery is right for you.
Everyone has their own opinion when it comes to choosing a good LiPo battery, so I recommend trying a few different kinds to see what you like and don’t like.
