Li-Po 1300mAh 7.4V 25C battery - Stick

Lithium-ion polymer (LiPo) batteries are the successor to the well-known lithium-ion (LiIon) batteries. The fundamental advantage of LiPo is undoubtedly the ratio of capacity to size. The batteries are very small and at the same time have a very high electrical efficiency, so that a suitable battery can be selected for practically any AEG replica. They have no memory effect. They can be recharged very frequently without having to be fully discharged. Frequent charging is an advantage for every battery type.

It is important not to charge a LiPo battery on less than 3V per cell to discharge and not over 4.2V per cell to overcharge. Another advantage of LiPo packs is the low percentage self-discharge rate. An unused battery loses about 3-5% of its energy per month. It is important to take care of an unused battery, as there is a risk that it will be discharged below the minimum permissible value (3 V per cell) if it is not used for a longer period of time and unintentional chemical reactions can occur, which can lead to a deterioration in the battery's properties, including permanent damage and, in extreme cases, fire. Unused LiPo packs should be charged to an average of 70%.

When used properly, a LiPo pack has an average service life of 500-700 cycles. An important factor is the temperature at which LiPo batteries can operate. Unlike other batteries, LiPo cells work well at low temperatures. However, they should be charged at room temperature. To maintain the good condition of LiPo batteries, it is necessary to balance them during charging with a service port, which most LiPo packs have (a good LiPo charger has a built-in balancer).
