Lithium-ion Polymer Batteries

Lithium-ion polymer batteries are rechargeable batteries. LiPo batteries are usually composed of several identical secondary cells in parallel to increase the discharge current capability, and are often available in series "packs" to increase the total available voltage.
 
The advantages of Li-ion polymer over the lithium-ion design include potentially lower cost of manufacture, adaptability to a wide variety of packaging shapes, reliability, and ruggedness, with the disadvantage of holding less charge. Lithium-ion polymer batteries started appearing in consumer electronics around 1995.
 
A compelling advantage of Li-poly cells is that specialized manufacturers can shape the battery almost however they please, which can be important in any kind of machines and tools with low space for the energy supply as for example mobile phone manufacturers constantly working on smaller, thinner, and lighter phones.
 
Li-po batteries are gaining favor in the world of radio-controlled aircrafts, RC cars, RC planes, RC helicopters, RC trucks, RC boats, gun models, E bikes, large scale model trains, small portable media player, tablet computers, cell phones, electronic cigarettes, and so on wide ranges where the advantages of lower weight and increased capacity and power delivery justify the price.
