Common parameters of lithium battery.best batteries for off grid solar

　　1. Voltage

　　Q

　　The power difference between the positive and negative of the lithium battery is called the nominal voltage of the lithium battery. The nominal voltage is resolved by the concentration of the electrical level and the internal electrolyte of the plate data.

　　Operating voltage

　　The operating voltage refers to the voltage appeared during the discharge process after the lithium battery is turned on, also known as the discharge voltage. The operating voltage at the beginning of the lithium battery discharge is called the initial voltage.

　　Lithium batteries commonly used voltage: 12V, 24V, 36V, 48V, 60V, 72V, etc.

　　2. Capacity

　　The power that the lithium battery can be given under certain discharge conditions is called the capacity of the lithium battery, which is shown in symbol C. The commonly used units are Anpei hours, referred to as An Shi (AH) or MAH (MAH). Its capacity is affected by the positive data, battery temperature, discharge rate, voltage, etc. it uses.

　　3. Internal resistance

　　The internal resistance of the lithium battery means that the current is resistant to the lithium battery, and the internal resistance will affect the voltage of the lithium battery.

　　4. Circulation life

　　The number of cyclic life of lithium batteries is generally used to indicate that a loop indicates that a complete charging cycle of a lithium battery (ie, the power of the lithium battery from empty charging to full, and then discharge from full to empty).

　　When the lithium battery is low at low temperature, the discharge platform will certainly decline. At high temperature, it will affect the cycle function of the battery and make the battery inflation. Therefore, batteries are generally recommended to operate within 0-40 ℃. Of course, in addition to being able to do business in low temperature environments -low -temperature lithium battery packs.
