Lithium Ion Polymer (LiPo) packs are the successors to the well-known Lithium Ion (LiIon) packets. The main advantage of LiPo batteries is the ratio of capacity to size. They are very compact in size, while maintaining a very high current efficiency, which allows you to choose the right package for practically every AEG replica. They do not have the so-called “memory effect”. They can be recharged very frequently without being discharged first. Frequent charging is beneficial for this kind of battery.

Remember not to discharge the LiPo pack below 3V per cell and not to overcharge over 4.2V per cell. Another perk of LiPo packets is the small percentage of self-discharge. An unused pack loses about 3-5% of energy per month. You should keep an eye on the pack, because during very long storage, discharge below the permissible minimum value (3V per cell) and irreversible chemical reactions may result in deterioration of the package properties, including permanent damage, and in extreme cases - ignition. An unused LiPo pack should have an average charge of about 70%.

When properly used, the work-time of LiPo packs is on average 500-700 cycles An important aspect is the temperature at which LiPo packets can operate. Unlike other rechargeable batteries, LiPo cells can cope well in low temperatures.  Instead, they should be charged in room temperature. In order to maintain the good condition of LiPo batteries, they should be balanced during charging with the service plug, which most LiPo packages have (a good LiPo charger has a built-in balancer).
