What do V and ah of electric vehicle battery represent? Now there is an electric motorcycle with 72v20ah batteries (composed of 6 small batteries). The merchant said that it can run about 50km. If I want to increase the driving distance, do I have to add 6 small batteries or 12345 batteries? Which one can run further, compared with the 72v20ah battery and the 60v20ah battery, driving on the same road, the same weight driver? In addition, what is the difference between parallel connection and series connection? What are the consequences?

V is the voltage, ah is the capacity of the battery
Electric motorcycle is a 72V 20Ah battery (composed of 6 small batteries). It is normal to run more than 60km (except for larger tires)
If you want to increase the mileage, add 6 same batteries (add one set, and then connect the second set after one set is used up)
72V 20Ah battery and 60V 20Ah battery, in the same car, the same road, the same weight driver driving, the same distance, 72V only faster

How many electrons is a Coulomb charge equal to

6.25 × 10 ^ 18 (6.25 times the 18th power of 10)

How many watts is 1Ah equal to

Ah and watt are two units of different physical quantities, which cannot be directly converted
