1.Voltage
Nominal voltage: 3.7V
Charging voltage: 4.1V~5V
Discharge voltage: 2.8~4.2V
Storage voltage: 3.7~3.8V
2. Capacity
The capacity of polymer lithium battery depends on the thickness, width and length of the battery. It is also related to the material and size of the battery.
To quickly estimate the capacity of polymer battery, the commonly used estimation formula (estimation only):
Capacity=thickness * width * length * K (K is in mah/mm ^ 3)
3. Internal resistance
Internal resistance refers to the resistance of the current flowing through the lithium battery when the lithium battery is working. It is mainly composed of electrode materials, electrolyte, diaphragm resistance and contact resistance of various parts, and is related to the size, structure, assembly, etc. of the battery.
4. Charging rate
Charging rate=charging current/rated capacity
The maximum charge rate is the safest, but not the best. A lower charge rate can better extend the service life of the battery.
5. Discharge ratio
Discharge ratio=discharge current/rated capacity
Discharge rate refers to the speed at which the battery can discharge safely. It refers to the current value required for the battery to discharge its rated capacity within a specified time. The data value is equal to the multiple of the battery's rated capacity, usually represented by the letter C.
