How to Tell If Traxxas Battery Is Bad – Complete Guide

Introduction

You are a passionate RC racer and you enjoy RC racing often. But recently you see a dip in the performance of your RC.

You’re thinking that it must be the batteries at fault. But you want to be sure about the idea.

So how to tell if traxxas battery is bad?

Look for any kind of physical damage. If there is any kind of puffing then it’s time to change them. Also battery not being able to charge or perform fully can be sign of a problem too. Check if the battery is delivering adequate voltage and has proper internal resistance. These are the key signs.

Well, that’s the gist of a very long topic. But to know better you must read the details. And that’s why we prepared this article for you.

So let’s get started!

How Do Traxxas Batteries Usually Perform?

Traxxas is quite a famous name in the RC racing circuit. They manufacture great RC cars which can be a fine choice.

Their cars are all electrical. That’ll save you from the hassle of carrying fuel all around.

But being electric has its own sets of problems. The first and foremost is the battery. You need to keep it charged and also take care of it.

Traxxas batteries are LiPo batteries. Which are pretty standard for RC cars. So how long do traxxas batteries last?

They must be charged for about 45-60 minutes at a time. According to lipo battery discharge rate, it gives you nearly half an hour runtime.

Which isn’t bad at all. Considering RC cars consume a lot of power while driving.

This is how your normal Traxxas battery should perform. But any abnormalities in the performance is unwanted. That could indicate that your battery might be failing.

There could be a lot of other signs that could tell you that your battery is going bad. And if you ignore the signs, you might further damage your RC car.

So you should check up on the battery often. And try to spot any abnormalities as soon as possible so you can work on that.

And to do that, you need to know about the common signs of a battery going bad. We’re gonna answer exactly that here.

So let’s find out!

Signs That Tell That Your Traxxas Battery Is Bad

When you buy your batteries new. It’s pretty safe to assume that they are in their best shape.

But as time passes, Due to continuous charges and discharges, they start to decay. And they do turn bad with time.

There are a few things that you can notice to see if your traxxas lipo battery is going bad. It’s important because it’s not ideal to run your RC car with bad batteries.

So let’s check out a few things we can check to see if the battery is up to the mark or not.

1. Looking for Change In Physical Appearance 

Firstly, your battery should look fresh. If you find any signs of burn or any types of disfiguration on your battery. Then that raises a red flag.

The most usual appearance problem that you’ll notice is a puffed-up battery. And depuffing a lipo battery can be hard.

Can you overcharge a Traxxas battery? Of Course, you can!

Overcharging is the primary reason behind battery puffing.

Or there could be some kind of Traxxas battery chemistry error. Because of that, the material can fail and the battery can get puffed up.

A puffed-up battery should never be used in an RC car. It’s really dangerous for the car as it poses a potential hazard. 

Solution

You can’t salvage a damaged battery. You need to get rid of it. But you have to do it with caution.

Puffed-up batteries can explode. And you can’t throw batteries wherever you want. Because there are toxic chemicals present inside the batteries.

So you need to carefully dispose of the batteries. Ideally in bins that are labeled with toxic waste.

2. Battery Power & Capacity Reduced  

This is a very obvious one. If after giving your battery a full charge, it underperforms. Then that could indicate that your battery is approaching its end days.

Traxxas batteries are pretty good when it comes to running. Giving a full charge for about 30-45 minutes will give you a run time of 40 minutes to an hour. This time can vary according to your usage.

You can consider your battery is underperforming. If you notice that the performance output is nearly 80 percent or lower than the out-of-the-box condition.

Or if your lipo battery won’t charge, that can be the cause of underperforming too.

Solution

Well, there isn’t much here that you can do. Batteries go through constant charge and discharge so their life gets shortened as well.

But before you decide to change your battery you should properly check if it’s really underperforming. Or it’s just not charged well.

Charge your batteries to the fullest. And then run till the battery gets completely drained. 

Do this 3-4 times and take notes of the charging time. And the time you’re getting in your RC. Then compare the percentage.

3. Fluctuation In Battery Voltage & Internal Resistance

The battery has a specific internal voltage. This is maintained very strictly as the internals of the RC car run on a specific voltage.

If your battery has a lesser voltage difference than normal. You’ll get less current delivered to your RC car. Thus decreasing its runtime and performance.

The same goes for internal resistance. Because higher internal resistance means less current flow.

If your battery has some kind of damage the internal resistance will increase. Then the current output will be lower than normal. Which will decrease your battery performance.

Both of these, voltage and resistance fluctuation indicate that your battery might be going bad.

Solution

Measure and make sure of the problem using a mutimeter. The multimeter can give you both the voltage rating and the resistance too.

Here are some multimeters that you can check out:

Product-1
Product-2

Hopefully this will help you out when you’re looking for a multimeter for your use!

Place the multimeter red wire to the battery’s positive terminal. And the black one to the negative end.  And then turn the multimeter knob to volt. Then the display will show you the internal voltage of the battery.

Match that with the label of battery and you’ll know if your battery is right.

To measure the resistance, you just need to add another resistor to the battery end and wire. Then turn the knob to ohm scale. And you’ll get your resistance reading too.

Well, now you should be able to notice if your battery behaves oddly. It’s very important to check your RC car and all its components regularly. Because one fault can turn the whole thing into a brick.

FAQs

Do LiPo Batteries Make RC Faster Compared To NiMH Batteries?

Yes, LiPo batteries are much faster than NiMH batteries. Even though both are electrical cars which are faster than nitro cars anyway. But LiPo batteries pack a punch of power and make your RC go even faster. For that reason, most professional RC racers prefer LiPo batteries over Nimh.

Can You Depuff A Puffed LiPo Battery?

No, there is nothing you can do to depuff your LiPo battery. Due to imbalanced charging and discharging, your LiPo battery can get puffed. There is nothing you can do to depuff it. Slightly puffed batteries can be used though. But that is dangerous and we advise strictly against it.

Can You Use Other Company Chargers To Charge Your Traxxas Battery?

Yes, you can if you maintain the voltage limit. But it’s not advisable to do so. It’s best if you can find any other charger from the same company. But if you have to use a different company charger. Read the label and make sure it supplies the same amount of voltage as your original one.

Wrapping Up

By now you should be clear about how to tell if traxxas battery is bad. It’s always convenient to keep a few sets of new batteries with you. In case you need charging so that you can continue having fun.

Until next time, stay healthy and happy!
