lithium ion polymer battery pack with 5200mAh capacity and 25C discharge rate

Application Field : Delong 5200mAh 18.5V Lithium polymer battery with 25C discharge rate will be suitable for 800mm RC Plane and Blade, Walkera, Esky Co-Axial Helicopters, Trex 250 ,RC Car,,RC helicopter

park flyers ,sports planes ,Micro RC airplane ,scale RC airplanes ,Amphibious airplanes .

Product feactures and characteristics : Delong high discharge rate lithium polymer battery delivers the lightest, most powerful energy , longest lasting working time and fastest charge rate ,Delong series batteries offer the highest energy

and power density in high-discharge rate capable Li Po technology, weighing less and delivering up to 60% more power and 100% more cycle life than recent generation Li Po batteries. That means more

power at less weight for up to an incredible 600+ cycles while also being capable of technology-leading charge rates up to 12 C* for charge times of as little as 5 minutes or less. This industry-leading performance

and capability comes as a result of building cells by using the latest in high-quality South Korea-made materials with advanced technologies and optimized compositions not found in other cells. These technologies

and materials, combined with the refined Premium Stack Technology (PST) construction, results in the lowest possible internal resistance (IR) and operating temps for maximum cycle life and the lowest cost per cycle.

RC LiPo Battery Storage

How a LiPo`s battery pack is stored between uses will greatly affect their life span. As mentioned, a LiPo cell that drops below 3 volts under load is almost always & irreversibly damaged. 3 volts under load is generally

equates to about 3.5 volts open circuit resting voltage, if your batteries are stored for any period of time after you use them at close to that magic 3.5 volt per cell number, you run that risk.

As batteries sit, they will naturally self discharge. LiPo`s are actually very good in this respect and self discharge much slower than most other rechargeable battery types, but they still do loose voltage as they sit. If you

leave them for a number of weeks or months at close to 3.5 volts per cell, chances are they will drop below the 3 volt threshold and could be damaged.You must store them charged, but not fully charged either. Basically,

the speed at which a LiPo pack ages is based on both storage temperature and state of charge.For optimum battery life, store your RC LiPo batteries at room temperature and at about 40-60% charged. That equates to

around 3.85 volts per cell. A good computerized charger will have a setting where you can charge you pack for storage, specifying the % of the battery capacity you would like to charge it to.
