LiPo 7.4V
Battery 2000mAh 15/30C – Nunchuck – T-Connect (Deans)

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. 

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 in-built
balancer).
