The voltage and capacity of a battery are limited. Therefore, batteries need to be combined in series and parallel to obtain higher voltage and capacity and meet actual power supply requirements.
Parallel lithium battery: constant voltage, capacity addition, reduced internal resistance, can prolong the power supply time.
Lithium battery series and parallel: the middle of the battery pack has both parallel combination and series combination, so that the voltage increases, capacity increases.
Serial voltage: 3.7V Single battery can be assembled into 3.7 x (N)V battery string (N: number of single batteries) as required.
For example, 7.4V, 12V, 24V, 36V, 48V, 60V, 72V.
Parallel capacity: 2000mAh battery can be assembled into 2*(N)Ah battery pack as required (N: number of single batteries)
For example, 4000mAh, 6000mAh, 8000mAh, 5Ah, 10Ah, 20Ah, 30Ah, 50Ah, 100Ah, etc.
