Li-Ion 7.4V 6000mAh Nunchuck (Tamiya) Battery 

A LiPo 7.4
V pack, designed especially with ASG electric replicas in mind. The pack
is equipped with a female Tamiya connector. High quality of constituent parts allow this battery to function for a long time on a single
charge. 

Li-Ion packs are characteristic for
increased energy efficiency. They do not feature the so-called memory effect,
that is why they can be charged very often (it is even recommended) and it will
not affect the packet’s qualities in a negative way. It is also characteristic
of them to have a small size in relation to the accumulated energy (they are
exceptionally small and light). This makes them very well suited for AEG
replicas.

Li-Ion battery should not be left
with a minimal charge for prolonged periods of time as that may lead to the worsening
of the qualities guaranteed by the manufacturer and to damaging of cells. 
In order to maintain safety, good performance and parameters specified by the
manufacturer, it is worth to remember not to discharge the battery completely
and not to overcharge. Li-Ion batteries have a low level of self-discharge.
Depending on the environmental conditions, it can reach up to 8% per month.
