Lithium-Ion-Polymer (LiPo) packs are successors to the known Lithium-Ion (LiIon) packs. The basic advantage of LiPo is undoubtedly the ratio of capacity to size. The packs are of a very small size whilst maintaining a very large electric efficiency, which allows for the choosing of an appropriate pack for practically every AEG replica. They do not feature a memory effect.  Can be charged very frequently, without the need to be fully discharged. Frequent charging is beneficial for every type of battery.

It is crucial to remember not to discharge a LiPo pack to a level of less than 3 V per cell and not to overcharge over 4.2 V per cell. Another advantage of LiPo packs is a small percentage rate of self-discharge. An unused pack will lose approximately 3 - 5% of energy per month. It is important to pay attention to an unused pack as there is a risk that as a result of not being used over a prolonged period of time it can be discharged beneath the acceptable minimal value (3 V per cell) and inadvertent chemical reactions may occur, which lead to a deterioration of the pack’s properties including a permanent damage and, in extreme cases, a fire. An unused LiPo pack should be charged to an average of 70%.

Properly used, a LiPo pack has an exploitation period of on average 500 - 700 cycles. An important factor is the temperature that LiPo packs can work in. In contrast to other batteries, LiPo cells perform well at low temperatures.  However, they should be charged at room temperature. In order to maintain the good condition of LiPo batteries, it is required to balance them during charging with a service connector, which most LiPo packs have (a good LiPo charger features an inbuilt balancer).
