Buying Guide

Alright, we have seen five products that are the best batteries for Traxxas Slash trucks available out there on the market. But how will you know which one is the most suitable product for you?

Okay, the way is simple. Let’s go through the basics of LiPo batteries

You’ll see, that this segment will help you make the perfect decision.

Battery Capacity

When deciding on the battery for the Traxxas Slash, the most important feature that you might have to check before buying is the battery capacity. This is also a necessary differentiating feature if you’re choosing between lipo and graphene

Well, capacity is something you need to check no matter what battery you’re going for. This doesn’t only apply to RC Trucks. Now, what is capacity?

Well, think of it as something like the fuel of a tank. It is measured in milliamps (MA). The higher the capacity of the battery, the longer the device will run. Thus, you want a battery with a higher capacity.

For instance, if you have the option of choosing between a battery with 6,200 mAh and 1600 mAh, choose the 6200 mAh. 

Battery Voltage (V)

Another key feature of a battery is voltage. This is measured in volts or V. The voltage of the battery tells you how much raw power your RC truck is gonna produce. So, when it comes to voltage choose a higher one.

That’s because the higher the voltage, the faster your car will run. So, whenever you go out on a race with your RC car, it will go faster. 

But the voltage of the battery depends on the number of cells you have on your battery. A battery with a higher number of cells will have a higher voltage.

So, when a battery has two or more cells attached together their voltage gets added. Meaning if there are two cells in a battery their voltage will be added together.

Charging Time

Traxxas trucks use Lipo batteries, they need to be recharged on a daily basis. So, try to ensure that the charging time for the battery is as low as possible. That will ensure that the battery gets charged really quickly.

So, how long does it take to charge lipo battery?

A LiPo battery of 11.1V and 5000 mAh takes up to 2-3 hours to charge entirely. However, it depends on the charging mode and the charger as well. It’ll take more time to charge if the voltage and capacity are higher.

This way, you won’t have to spend a long time behind this. It will be over in a jiffy and you will be able to get on racing the RC car again. Besides, who likes to wait, right?

The Lifespan of The Battery

Now, let’s focus on the lifespan of the battery. It is natural you would want a battery to serve you a long time. So it is a must to check the lifespan of a battery. This way you can ensure the best battery. 

A lithium-ion Polymer battery lasts up to 150-200 charging cycles on average. However, some of the batteries might end up having 300+ cycles in them.


Durability is an important factor when choosing a LiPo battery for the Traxxas slash. As it is an off-road RC car it will often fall or get splashed in the water. So, are lipo batteries waterproof?

YES, LiPo batteries are 100 percent waterproof. It comes in an airtight outer body through which neither air nor water can penetrate. this makes them usable in different kinds of terrain and weather.

However, if you’re paranoid about the waterproofness then you can use automotive-grade silicone sealant to make the LiPo batteries waterproof. Make sure you apply the sealant thoroughly over the seam of the outer body. and the joints of the wirings.


How to Charge a LiPo Battery with a Traxxas Charger?

Plug in the balance plug of your Lipo battery on your Traxxas Ez-Peak Charger. Then hold the start button and the charge rate select button together for two seconds. Now select the charging rate and the charging mode. Finally, press the charge button and it’ll charge.

Why does LiPo Battery Swell?

When LiPo batteries decompose they tend to release Carbon dioxide (CO2) and Carbon monoxide (CO). The swelling of LiPo batteries is caused by this gas production.

How to Tell if LiPo Battery is Bad?

Check if your LiPo battery is swollen or has any physical damage on it. This will indicate that it’s deteriorating. You can also check the IR (Internal Resistance) this will indicate how efficient the battery is. A higher IR value will indicate a lower efficiency.

To Sum Up

Well, that’s all for the best Lipo battery for Traxxas Slash. Don’t forget to study the things discussed in the buying guide.

The more you will know the best battery you will be able to pick for your truck.

We think we have covered everything you’ll need to know before buying the best battery for your RC and gave enough info to help you make a decision.
