Problem 2: Low Voltage Error

This is another problem that is very common. So you have 3ser batteries. But the charger reads 2ser.

However, when you choose 2ser, it charges for approximately 25 seconds. Then it stops as it’s full but surely is not.

Also, if you plug in some other clips, it says ‘voltage too low.’

Solution

This is another common problem that comes with the venom pro duo charger. However, you can quite simply solve it as well.

Only if you follow the step-by-step process provided below.

Step 1: Enable a Low Charge Rate

Now the first thing you are gonna do is try charging your lipo as a NiMh

However, do it only long enough until you get voltage back over 9 volts!

Because when you leave lipo charging as NiMh, it’ll damage it. Also, it will probably vent and catch fire.

So you’ve to instruct the charger that it’s a 7 or 8-cell pac. Thus it would enable it to charge at 0.1 to 0.2 amps. It should not go any higher. 

And you want to have a low charge rate. Otherwise, the voltage will go up too fast. It can eventually damage the lipo. 

Step 2: Take Action Immediately 

If you notice the voltage up over 9 volts, immediately stop the charge. 

Do not leave when the charging is going on. Carefully scrutinize the charger all the while and then voltage on the lipo.

Step 3: Complete the Process

After you’ve done everything mentioned in the previous steps, you need to switch to a lipo charge. Then it should charge naturally. 

However, there are chances that you may see the lipo begin to swell some time. It may also start overheating. If so, you need to disconnect everything. Then take the charger outside. You have to leave it there for at least a day. 

Because It’s an indicator that it has become potentially unsafe. If the swell does not get any bigger, then you may try reseeding with it.  

However, it is better if you do it outside. Because, this way, if anything happens, it won’t ruin anything.
This is typically how you can rescue an undamaged lipo battery that’s been a little over-discharged. Thus saving you venom pro duo charger.

Frequently Asked Questions (FAQs)

Why is my venom charger flashing red?

The venom charger flashing red implies that the battery voltage is maybe too low. If so, the red light is supposed to blink about 90 seconds after the battery insertion. In that case, just leave the batteries in your charger for around 24 hours. Then you can remove the battery.

Is it possible to bring a LiPo battery back into life?

To bring a lipo back to life, first move your battery over to the Lipo balance charger. Do it when the cumulative voltage is about 3.3 volts per cell. Keep the balance charge rating at 0.5C rating. It may take longer than charging at 1C. However, it is safer.

How will you understand when your venom battery pack is charged?

Well, there is actually no way to tell if or when they’re fully charged. Because they only flash a severely bright green light when charging. The LED also won’t change color. Even won’t stop the flashing light when fully charged.
