Information about LiPo batteries

LiPo stands for lithium polymer and is regarded as the battery of the future, offering longer runtimes and higher performance. The high number of possible charging cycles also speaks in its favor. Depending on the manufacturer, the service life is specified as 300 to 600 charging cycles. In addition, LiPo batteries have no memory effect, which means that they largely retain their capacity over their entire service life, with only a slight loss of around 20 %. However, this service life is shortened if they are not stored at a storage voltage of 3.8V. The battery should therefore be charged to this voltage after each use.

Charging LiPo batteries

When you buy a LiPo battery, it must first be charged. It is important to ensure that the charger is compatible with the LiPo battery. This information can usually be found on the charger, on the packaging or in the manual. If you have a suitable charger, you must know the correct settings for charging the battery.

It is important to understand what the information on the battery means: A LiPo battery consists of at least one cell, which is usually 3.7 volts. The "S" value indicates the number of cells. A 2S battery therefore has 7.4 volts (or 7.6 volts for a high volt battery). The current rating in amperes shows how much current the battery can supply.

What is the C value?

The "C" value is an important factor for charging and discharging. It indicates how much current can be drawn from the battery for a short time. To do this, the ampere value is multiplied by the "C" value. In simple terms: A battery with 6000mAh and 50C can deliver up to 300 A at the output. It is said that the higher the C value, the more pressure (punch) the battery provides when riding on the track!

Safety - an important issue

LiPo batteries require special safety precautions. Many people have heard of exploding batteries. Common causes are overcharging or mechanical damage. To minimize the risk, you should always use a LiPo charger with the correct settings. It is also advisable to charge the battery in a LiPo safe bag and store it in this bag at the correct storage voltage.

How do I store LiPo batteries?

Storing LiPo batteries correctly is crucial to prolonging their service life. If they are stored for more than two weeks either empty or fully charged, this can severely affect their performance and service life. When not in use for longer periods (more than one week), use a programmable charger to bring the battery to storage voltage in storage charge mode. If no such device is available, charge the battery for about half the time that would normally be required for a full charge.
