Venom Pro Duo Charger Problems- Briefed with 3 Solution


Venom’s Pro Duo AC/DC battery chargers really stand tall when it comes to charging convenience. As a result of its height rather than width, it occupies less bench area than two battery packs.

Even so, you may run across some common issues that you can’t figure out how to deal with. Even you can lose track of the issues from time to time.

How to fix venom pro duo charger problems?

Some common problems are like your  Venom pro duo charger suddenly beeps red. Charge it properly. Turn on Nimh until the cells reach 3V in a short time for low voltage. A disturbance in voltage and charge readings may happen. Charge the NiCd or NiMh batteries at 0.5 amps on a charger set.

Let’s crack the whole article for more information. 

Why You’ll Use Venom Pro Duo Charger

Venom pro duo charger is top-notch. It is capable of charging several Lipo batteries. They’re connected to a balance board at a rate of up to 7 amps with no issues. 

For your RC truck, you can also use it to recharge some NiMH batteries. It occupies only as much bench space as two battery packs. 

You get a pair of balancing boards, as every sort of plug you could possibly need. So you can power everything from your receiver pack to a 6S LiPo. 

It comes with the transformer power inside the case. Programmability is built-in, including modes for lithium, nickel, and lead-acid batteries. As well as you can find a variety of other battery types. 

Common Problems in Venom Pro Duo Charger

You can have some issues with the venom pro dual charger while trying to use it. However, when it comes to the use of electrical items, this is very typical.

The venom pro duo charger has a few typical issues. Let’s get together and figure out how to deal with them.

Why Is My Venom Pro Charger Beeping Red??

A red light indicates that the battery has run out. The manufacturer of these batteries makes them with a short life cycle, forcing you to buy more.

Also, the prongs are mechanically blocked by dirt, dust, and/or greasy debris from your hand. These can cause problems with charging ports, resulting in poor connections, and beeping red. 


As you can’t fix the drained battery, all you have to do is charge it properly. Check those batteries if they’re actually drained or not. You can fix LiPo batteries by removing dead cells.

In order to test whether the battery is still alive, remove it from the control system. Hold it on the charging station prongs for a few seconds (without interrupting the connection). 

Also, check that the prongs are aligned precisely. If the battery continues to flicker, it’s time to replace it. 

If there’s no blinking and the charging normally, the problem was probably caused by a bad connection. Try moving the controller or charging it without the rear cover to see if it helps.

You should use a gentle cleaning solution for cleaning dirty prongs. Such as rubbing alcohol and clean cloth that won’t produce lint, or cotton swabs and Q-tips.

Low Voltage on Lipos While Using the Venom Pro Charger

A low voltage is a warning on the venom pro charger. It’s a sign that the batteries are dead. The same error notice appears when you try to balance them.


The charger’s low-voltage cutoff has been reached with the battery pack. Packs can be damaged if they fall to a dangerously low level over an extended time. Keep checking the lipo battery discharge rate.

There’s going to be a lot of monitoring required for the ones that have been revived. Turn on Nimh until the cells reach 3V in a short time.

Then switch to balancing charge at lower than 1C. A cell should be discarded if it has fallen below 2.5V for an extended period.

A Disturbance in Voltage and Charge Readings

It appears that you may be dealing with a separate problem altogether. For example, when fully charged, the battery’s voltage is roughly 8.4V. 

The boat’s ESC does not beep and does not respond. It is broken to refute the boat or the batteries, you want to try some new NiMHs.


Charge the NiCd or NiMh batteries at 0.5 amps on a charger set to NiMh or NiCd. Don’t connect the balancing tap. Instead, connect the charge lead to the pack’s output leads. 

Activate the charger. Keep an eye on the pack for a few minutes before checking the voltages of the cells. Checking voltage can help you to find out if Traxxas batteries are bad.

You can finish charging and balancing the batteries once they’ve reached about 3 volts per cell. Then switch the charger to LiPo mode and attach the balance tap. 

You can check these suggested tools for replacing new batteries-

Product 2

Always keep an eye on the lipo batteries when charging and while using it, as previously advised. You should throw away any cells that continue to lose voltage or are unbalanced.

Ways to Stay Ahead of Problems

Venom pro duo charger is simple to use. It has a slew of features for quickly and safely charging individual cells. That’s why using this battery is super convenient. 

Avoiding common and foolish battery problems is easy if you know a few strategies. Let’s have a look at them-

Tip 1: Don’t Overcharge

LiPo batteries should never be overcharged. 4.2 volts per cell is considered to be a full charge. Avoid “trickle charging” LiPo batteries at all costs.

Tip 2: Avoid Discharging

When recharging NiMH batteries, avoid completely discharging them first. To extend the useful life of NiMH batteries, it’s recommended that you never totally discharge them.

Tip 3: Avoid Undercharging

Don’t undercharge the battery. Under-charged batteries cause poor RC efficiency. Every RC model enthusiast knows that having fun in the pastime necessitates good battery management. 

It’s a quick way to finish a long day of racing if the battery is overcharged. Incorrectly discharging or storing batteries is a common cause of decreased performance and speed. 

Additionally, LiPo batteries must be charged carefully. Since improper handling or misconfigurations might result in swelling or catching fire. 

A high-quality RC battery charger is an absolute necessity, only for efficiency and safety.


How long can I leave my LiPo battery to charge before I use it?

LiPo batteries typically take 30-60 minutes to charge. The amount of time it takes to charge a battery depends on its size or cell count. 

How long does it take to recharge a venom battery pack?

It takes 2 and a half hours to recharge fully. Only one of the packs can go from 100% to zero charges in around 15 minutes.

What does it mean when the venom charger lights up?

There are several reasons why the CHARGE light can be flashing. The battery pack can’t be charged since it’s too cold outside. Or it’s been a long time since you’ve utilized the battery pack. The battery and charger have a bad connection.

Final Words

We’ve discussed here in detail venom pro duo charger problems and their solutions. This should help with the charging batteries, and we sincerely hope it does.

The Venom Pro Duo’s biggest feature is how simple it is to operate. When it comes to charging your batteries, you don’t need a degree in battery chemistry. Just assure that you’re doing so in a safe manner.
