The battery is the fuel of an RC car. Properly charging a battery is very crucial for the car’s performance.

Apart from blinking red, SCX24 chargers might blink red and green too.

There are several possible reasons behind this. But don’t worry, We have listed the possible reasons and their solutions for your convenience.

Reason 1: Broken Charger

The most common and obvious reason for blinking red lights is the charger is broken.

This could happen due to physical damage or factory issue. 

Also, reckless handling might cause the charger to break off.

Solution: Get a New Charger 

If you have a warranty on your device, you can go to the dealership. You can ask for a replacement. Otherwise, you need to buy a new one.

SCX24 chargers aren’t readily available everywhere. As a result, you may have to run into trouble finding the charger.

But wait! There’s good news. There’s an amazing charger that is compatible with SCX24 and can be found easily. 

Now, from my years of experience collecting RCs, I know a few things or two. One of them is finding the right chargers. 

When I came across the Blomiky 7.4V 800mA 2S Lipo Li-ion Battery Balance Charger, I didn’t know you could charge SCX24 with it. But after probing around I discovered this and I cannot recommend it enough. Not only is it compatible with your SCX24 but it also provides fast charging. 

Reason 2: Loose Connection 

Another key reason for this issue is a loose connection. This happens in many cases when the battery or the charging plug is loosely connected.

This might cause connectivity issues and result in blinking red and green.

Solution: Repair the Connection

While connecting the battery to the charger follow the scx24 charging instructions. Check to see if any of the connections are loose or not. 

If you find your battery connection to be loose, then get a good wrench and fix the bolts that connect the wires to the main battery brick. This should solve the issue. 

Reason 3: Defective Unit

You have checked everything and all connections. But the charger is still blinking red and green. This could be because the charger unit is broken. You need to check the charger.

Production errors or faults may happen and you might get unlucky with your purchase.

Solution: Replace the Charger

If everything is okay and it’s not working, go to the retail shop. Show them the problem and ask for a replacement. 

I’ve previously mentioned how much I love the Blomiky 7.4V 800mA 2S Lipo Li-ion Battery Balance Charger. You can use this as a replacement for your old SCX24 charger as well. 

Reason 4: Battery Problems

The battery could be another reason for the error. Li-po batteries are very sensitive and can be dead in no time.

Sometimes, a small mistake can damage the battery or its charging capacity. This will result in no charging and light blinking.

If your battery health and voltage are not good, replace them. You may also need to depuff the battery

If you find your batteries to be damaged beyond repair, then get some new LiPo batteries. Personally, I’ve tried a lot of LiPo batteries for my SCX24 but I always fall back on two batteries in particular.

Lastly, you should always follow the proper way of charging SCX24 batteries. Otherwise, it will be more prone to damage.
