Buying Guide

How do you feel after going through 5 different products?

Pretty sure your mind is jammed because of all the truck-load of info. So, how about we help you sort things out with our very own buying guide.

This will map out a way for you to determine the important features needed for a battery. All of this will help you figure out which one you should go for.

So, if you’re up for it, let’s start-


One of the main things you’ll encounter with a battery is its voltage. Its symbol is V which stands for volts. Now, you might know this but what does the voltage indicate?

Well, when it comes down to battery voltage determines how fast your RC car will go. Thus if you have a higher voltage your car will go faster. On the other hand, a lower voltage indicates lower speed for your RC car.

Now, the best part about the battery is that they can be stacked together to increase the voltage. Hence, if you have two batteries of 3.5 V you’ll get a total voltage of 7 V.

However, there is a limitation when it comes to RC cars. So, you won’t be able to throw in a lot of batteries. But it’s good to know that increasing the number of batteries will make cars run faster.


Another thing that you might come across is the capacity of the batteries. Do you know what capacity indicates for your RC car?

Well, it tells you how long your RC cars will run. In other words, it’s the amount of time the battery will work to make your RC cars work.

However, you might come to the conclusion that batteries with higher capacity are better. That might be the case if you think about it. At the end of the day, your Rc car will run for a long period of time.

But for that to happen you’ll have to charge the batteries for a long time as well. So, if you’re willing to do that you can definitely go for a battery with high capacity.

Discharge Rate

The discharge rate is also called the C-rating. It’s basically how quickly the battery can be discharged without destroying the battery.

Typically, the batteries for Traxxas Slash have a discharge rate of 25C. And this is standard for this model of RC. However, some people tend to spend more money to buy batteries with higher discharge rates.

Now, they won’t make your RC car go faster. No, instead they will only be more pricey and will probably put a hole in your wallet.


Some of the batteries out there tend to get hot. This way, they spend a lot of energy. And these energies are wasted. Thus, the overall efficiency of the battery decreases and they don’t serve their full lifetime.

Hence, try to go for the more efficient ones. That means lookout for the batteries that do not get hot that easily. The Lipo batteries are quite better in this case than the NiMH.

Note: After getting the battery, you should do match the lipo battery with your RC motor. This is super important!


Question: Is it OK to leave a LiPo battery charge overnight?

Answer: Leaving a Lipo battery charger full overnight is ok. However, don’t leave it for more than 2 to 3 days. The batteries can become overcharged and dissipate the excess heat by harming themselves. So, discharge it if you’re not using the battery.

Question: Do LiPo batteries last longer than NiMH?

Answer: NiMH batteries can last for more than thousands of cycles. Plus they can store charges for quite a long period of time. However, the LiPo batteries can only last for 100 to 200 cycles. So, you’ll have to replace it frequently.

Question: Can you charge a non-Traxxas battery on a Traxxas charger?

Answer: Yes, you can use Traxxas chargers to charge the non Trannas batteries. However, before that, you have to change the program for the charge for the charger to work properly with the batteries.

Question: Do Traxxas batteries go bad?

Answer: Traxxas batteries are quite long-lasting. However, due to prolonged racing they can go bad from time to time. So, you should always keep a spare battery with you.
