Li-Polymer battery has widespread application in many electronic products for its performance advantage. Especially the Lion Power li-polymer battery has got very hot in recent years. For example, Lion Power 11.1V 5200mAh is designed for RC helicopter and lot of players prefer to choose this brand rechargeable battery. Why does it enjoy such a high reputation? What you kind of feature you want to pay if you buy a rechargeable battery for your copter?
When it comes to li-polymer battery, the length of its service life must be concerned. To estimate the service life of rechargeable battery, you should get to know the number of its internal resistance. Casually, the smaller the internal resistance is, the longer life the battery has. Lion Power 11.1V 5200mAh has relatively small internal resistance but large capacitance. Small internal resistance battery will not suddenly fail or can not be full charged. Many people feel confused why it gets so hot with such little power, and I bet you have idea now. What’s more, every kind of rechargeable battery has fixed number of charging. The greater the capacitance of the battery is, the longer the each working time it has. That is to say, rechargeable battery of high capacitance services longer time than those battery of relatively low capacitance.
Choosing a longevity of rechargeable battery like Lion Power 11.1V 5200mAh li-polymer battery saves you a big of unnecessary outcome, and ensure the safety of your RC helicopter. The smaller internal resistance reduces the risk of battery burning down, at the same time, it reduce the risk of RC copter burned by the burning battery. Also the high capacitance services longer time for your copter. As long as you charge it properly, it could be used for several years. And you will find you would not buy rechargeable battery so often.
