How To Charge A Lipo Battery For The First Time?

Li-Po battery is defined as Lithium Polymer batteries. It’s one of the most revolutionary inventions of modern technology because it replaces conventional batteries. It brings higher battery life to the devices to use the devices without interruption for a long time.

But there are some rules you need to follow if you are a newbie to charge a lithium polymer battery. You might be thinking about how to charge a lipo battery for the first time. Or will there be any problem if you do not do it properly?

How To Charge A Lipo Battery For The First Time?

Stay with the article till the end and get to know all the answers to your questions. We will discuss this in detail to clarify your concern.

Remember To Read the Manual

No matter what type of charger and battery you get, there will always be a manual. It is because the manual has the instructions of the current rate, voltage amount, charging time, safety procedure, etcetera. Another reason is that not all the Li-Po batteries are the same.

Different types of batteries will need different charging rates, voltage, and other like safety measures. We will always say that manufacturers know better than you. Therefore, you must follow the instructions.

How Should You Proceed?

If you are using a Li-Po battery for the first time, you must strictly maintain some instructions. We will try to discuss every point broadly so it would be for you to understand.

Know Your Battery

Read the instruction manual to know which type of battery you have bought. You will also have to know how fast you should charge the battery. It is because you never want to charge a battery faster than you will need to. Most of the batteries will show “1C” written in their body. It means safe in slow voltage.

See the Charging Speed

You will notice two things written in your battery’s body. One is MAH which defines the capacity, and another one is AMPS which defines the charging rate. If you see 5C on the battery, which means you can charge it at 5AMPS. When the number is 1.5, then you will have to charge it at 1.5 AMPS. You get the idea right!

See When You Discharge

The charging procedure is a little bit different. Some experts say you must discharge at a capacity of 50 percent when the charge speed is 1C. The cycle must repeat five times. Then it is good for us. If the charging speed is like 4C or 5C, you should directly discharge after 100 percent of capacity.

Balance Charging

Most of the Li-Po battery chargers use a balance charging system. It means it will charge the individual cells of the battery individually. You will see two types of cable in a single battery. Comparatively, thick wire is your main power lead, and thin wires are balance lead. The balance lead contains one wire for each cell.

Connect With Charger

Connect the cable to the charger, and the red lights will indicate if it is charging or not. If you are using an analog charger, the green light will show the time to discharge. The lights can also define the number of individual cells charging in the battery.

Use Protective Gears

When you put the cables into the charger, make sure your battery is in a Li-Po safety bag. Just put the battery into the bag and let it be there. When the charging is complete, you can pull the battery off from the bag and use it. A steel container can also replace the safety bag.

But that will not be comfortable. The safety bag is necessary because batteries can damage you and your properties by busting out or burning.

There is a device called Li-Po alarm. It will warn you when the charging is complete. This alarm can warn of even any overheating issue.

Digital Chargers

Nowadays, you will find many digitals chargers by which you can control the charging speed along with the voltage. First of all, input the balance connector into the charger and the power cables. You can use a converter if the power cables are not compatible with the charger.

Before you start the charging, you need to input the cell numbers, which you will find in the manual. Some chargers have automated sensors to identify the number of cells. You have already learned the AMPS calculation, which was discussed earlier.

Therefore, you have to set the charging rate and press start. Always remember to stay in the range of charging speed and not exceed it. It is very safe to charge in 1C unless you are in a hurry. There is another term known as storage charging. It is like putting your battery to a lower charge which is safer for batteries. The internal resistance will demolish at a slower rate in storage charging.

Do I Need To Fully Discharge Before Charging?

No, that is not necessary if you are charging the battery for the first time. It is because all the Li-Po batteries are partially charged when you buy them. Therefore, you should charge the battery fully before you start to use it.

Should I Charge The Battery Overnight?

The first thing about Li-Po batteries is to avoid overnight charging. The experts recommend not to leave the room while you are charging the battery. It is because overcharging will damage your battery life and its efficiency. Sometimes it may explode or get a thick belly which could be dangerous for you.

Some Pro-Tips for You

  • Always buy batteries from reliable companies
  • Use the safety Li-Po bags while charging
  • Use battery balancer
  • Try to avoid hotter places where you keep the batteries
  • Do not let the battery overheat during charging

Bottom Line

Lithium polymer batteries are very useful in our life. Whenever you need a power source for a device, the first thing that will come to your mind is Li-Po batteries. But some wrong steps during charging will reduce its lifespan.

Hence, you need to know how to charge a Li-Po battery for the first time. Then there will be fewer problems if safe methods are used in battery charging.
