LiPo 7.4V 600mAh 20/40C Battery for PDW –
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. 

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).
