LiPo 7.4 V 250mAh 25C HP - JST battery

Especially for Valken V-12 engines developeda small LiPo 7.4V package with the dimensions 10x20x40 mm. The pack has a JTS connector with a male end. Thanks to the high quality of the components and the low power consumption in V-12 motors, this battery can run for a long time on a single charge. Thanks to its compact size, it can be used not only with HP motors, but also as a power source for electric gun replicas (AEP). 

Lithium-ion polymer (LiPo) batteries are the successors to the well-known lithium-ion (LiIon) Batteries. The fundamental advantage of LiPo is undoubtedly the ratio of capacity to size. The batteries are very small and at the same time have a very high electrical efficiency, so that a suitable battery can be selected for practically any AEG replica. They have no memory effect. They can be recharged very frequently without having to be fully discharged. Frequent charging is an advantage for every battery type. 

It is important to have a LiPo-Battery does not charge less than 3V per cell to discharge and not over 4.2V per cell to overload. Another advantage of LiPoThe main advantage of rechargeable batteries is their low self-discharge rate. An unused battery loses about 3-5% of its energy per month. It is important to take care of an unused battery, as there is a risk that it will discharge below the minimum permissible value (3 V per cell) if it is not used for a longer period of time and unintended chemical reactions can occur, which can lead to a deterioration in the properties of the battery, including permanent damage and, in extreme cases, fire. Unused LiPo-packs should be charged to an average of 70%. 

When used properly, a LiPo-pack has an average service life of 500-700 cycles. An important factor is the temperature at which LiPo-batteries can work. In contrast to other batteries LiPo-cells work well at low temperatures. However, they should be charged at room temperature. To maintain the good condition of LiPo-batteries, they must be equalised during charging with a service connection, which most batteries have. LiPo-packs (a good LiPocharger has an in-built balancer).
