Information about LiPo batteries

LiPo stands for lithium polymer and is considered the battery of the future, offering longer runtime and higher performance. The high number of possible charge cycles is another advantage. Depending on the manufacturer, the service life is stated as 300 to 600 charge cycles. Furthermore, LiPo batteries have no memory effect, which means that they largely retain their capacity throughout their entire service life, with only minor losses 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. You must ensure that the charger is compatible with the LiPo battery. This information can usually be found on the charger, the packaging or in the manual. Once you have a suitable charger, you need to know the correct settings for charging the battery.

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

What is the C-rate?

The ‘C’ rating is an important factor for charging and discharging. It indicates the maximum current that can be drawn from the battery for a short period. To calculate this, multiply the ampere rating by the ‘C’ rating. Put simply: a battery with 6000mAh and 50C can deliver up to 300 A at the output. It is said that the higher the C-rate, the more power (punch) the battery delivers when driving on the track!

Safety – an important issue

LiPo batteries require special safety precautions. Many people have heard of batteries exploding. Common causes include overcharging or mechanical damage. To minimise 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 to store it in this bag at the correct storage voltage.

How do I store LiPo batteries?

Storing LiPo batteries correctly is crucial for extending their lifespan. If they are stored either flat or fully charged for longer than two weeks, this can significantly impair their performance and lifespan. If the battery is not going to be used for an extended period (more than a week), use a programmable charger to bring the battery up to storage voltage in storage charging mode. If no such device is available, charge the battery for approximately half the time that would normally be required for a full charge.
