Here's to 11.1V lithium batteries for the remote control model aircraft examples of how to properly use lithium battery. Typically, 11.1V lithium battery remote control model aircraft by three lithium batteries in series (that is, the popularity of the most widely 3S battery, Figure 1), that every piece of batteries voltage 3.7V.
The lithium model, cell phones, cameras, etc. is called the voltage indicated marked voltage is obtained from the average working voltage. The actual voltage of lithium batteries is monolithic 2.75 ~ 4.2V, a lithium battery power subject to the charge-discharge capacity of 4.2V 2.75V obtained. Remote control model aircraft use lithium batteries must be kept within the voltage range of 2.75 ~ 4.2V.
Remote control model aircraft such as the battery voltage is lower than 3.7V belongs excessive discharge, lower than 2.75V is a serious over-discharge (battery causing damage which is fatal), then lithium expands, chemical liquid will crystallize inside these there might pierce the internal crystalline structure layer caused by a short circuit, and even make lithium voltage becomes zero, that this battery can scrap it, even if there is no serious results appear above the crystallization also make battery capacity and discharge rate declined significantly, so that the battery value greatly reduced, so usually good habits is the only way to increase battery life!
Remote control model aircraft lithium battery voltage is above 4.2V belong to overcharging, internal chemical overreacting, lithium will blow expansion, if it continues to charge will burn or explode (Figure 2). So, whether it is over-discharge or overcharge lithium would have devastating injuries. Therefore, we recommend using the safety standards of the regular charger to charge the battery while the charger is prohibited unauthorized alterations, which may result in very serious consequences!
