By applying lipo batteries, electric cars drive faster and longer than ever before. For many lovers of rc cars is that reason enough to use the lipo battery in their electro rc car.

However, the lipo battery is a relatively sensitive battery, where a lot and quickly something can go wrong when you charge, use and store the lipo battery incorrectly.

What can go wrong with lipo batteries

Lipo batteries can explode if you go wrong with them. But it is more likely that you inadvertently damage a cell in your battery. Fortunately, that is less disastrous, but your car will drive considerably slower.

With a lipo battery, you must also pay attention to what you do. And first and foremost always use a charger specifically designed for charging lipo batteries.

You also have to check whether the speed controller in your RC car is equipped with a safety device that prevents the over-discharge of lipo batteries.

It is not an insurmountable problem if your speed controller does not have this security. Because you can always place a device yourself between the cruise control and the battery that takes on this task.

A device that will be for sale in the better model shop.

These two precautionary measures ensure that your lipo batteries are already very well protected against accidental abuse.

But there is one thing you should always take care of if you are going to keep your lipos unused for some time. And that is that you never keep them while they are empty, and they never keep them while they are completely full.

It is best to always keep your lipo batteries half full. A good lipo charger has a special program for this purpose, with which you can provide your battery with the correct charge level before you store it.

How you use lipo batteries correctly

The right lipo charger

To be able to deal with a lipo battery, you will first need a charger, especially for charging lipo batteries. A lipo charger differs from other chargers, among other things because of the possibility of measuring the voltage of the cells in the lipo battery separately during charging.

Such lipo chargers could also be called lipo balancer. Because they not only ensure that the lipo battery is charged, but also that all the cells in the battery are fully charged.

Something that is vital for a lipo battery.

Because so to speak, if a lipo battery is too discharged, it will at least be damaged. To be precise, if a cell in a lipo battery is too discharged, it will be irreparably damaged.

The balancer function in a lipo charger is therefore a very important one.

Furthermore, a good lipo charger has a so-called storage program. A charging program that is intended to charge or discharge a lipo battery to a charge level where long-term storage is not a problem.

The best lipo charger for your money is also a charger that has a sufficiently powerful power supply. Because in short: the more powerful the power supply of the charger, the faster the charger can charge the battery.

Load correctly

A lipo battery can not be loaded without limit. How fast you can charge a lipo battery is usually indicated on the battery, or on the battery pack. Always keep your teeth clean, in order to prevent damage to the lipo.

How fast you can charge a battery is usually shown in a number of C. 1C stands for 1X the capacity of the battery. That means that if you have a lipo with a capacity of 5000 mAh, or 5 Ah, you can charge the battery with a maximum of 5 amperes.

If it is mentioned that you can charge your battery with 2C, that means that you can charge your lipo battery with 10 amps, and so on.

If you can not find anything about how quickly you can charge your lipo, always keep 1C at maximum.

If you are going to charge a new lipo battery for the first time, it is also advisable to charge it with only 1C. And it is also advisable to use the balancer function of the charger.

Because especially when lipo batteries are new or have a time, the cells can be somewhat out of balance.

Cleverly, therefore, new lipos certainly not completely empty the first few times. The reason is also this time: prevent one of the cells from being overloaded by accident.

Use it correctly

Using a lipo battery in the right way starts with choosing the right battery .

Choosing the wrong battery could result in your engine and speed controller demanding more power than the lipo can deliver. Something that will eventually lead to a damaged lipo battery.

There is a damaged lipo battery when it gets hot during charging and / or while using the battery in the car.

You should certainly no longer use a lipo battery that is full of bulbs.

A battery is worn out and out of date. There is nothing to do about that. But it can be postponed. And by dealing with your lipo battery as well as possible.

You have already been able to read a lot about how to deal properly with your lipo batteries. But one last thing you should remember is that you should not charge a lipo battery more than 4.2 volts per cell. For a battery of an electric car, which usually runs on batteries that consist of 2 cells, that means a voltage of 8.4 volts.

Furthermore, you should always prevent a lipo battery from being discharged further than up to 3.0 volts per cell, or 6.0 volts for a lipo battery of an electro rc car that consists of 2 cells.
