Lithium-ion polymer cells are among the latest Changes in the battery region and are capable of a large amount of energy at low weight available to ask. Therefore, these new batteries are also used for various Model disciplines very interesting. The presented Charging circuit for widespread battery packs with three cells connected in series and 11.1 V nominal voltage designed.
Lithium-ion polymer cells, often simply referred to as lithium polymer cells, are still fairly new on the battery market,
but have due to the high energy yield already a wide range of applications conquered. Especially in the field of model, where it comes to light weight Lithium polymer cells have a Cell voltage of 3.7 V, whereby the The final charge voltage of 4.2 V per cell must necessarily
