LiPo 7,4V 600mAh 20/40C Battery for PDW – Tamiya

Specna Arms  meets the expectations of their clients by supplying the market with a wide array of efficient LiPo batteries that meet the needs of every user – no matter if you are looking for a stock-stored battery, a handguard-stored battery or a battery stored in the laser sight case – this and much more can be found in the offer allowing for even longer games.

The battery is intended and ideally-compatible with Specna Arms EDGE replicas equipped with PDW stocks.

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. Packs are of very small size whilst maintaining a very high electric efficiency, which allows for 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 a 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).
