Whether it is an electric bike that exceeds the standard or a national standard electric bicycle, it will be a means of transportation for the general public in the near future. Electric bicycles or electric bicycles have entered thousands of households and are closely related to people's lives...

The maximum charging current that lithium-ion batteries can accept is usually 1C or even smaller. The so-called 1C charging rate refers to charging at a current rate of 1 times the capacity, with a charging time of 1 hour. In fact, to achieve a long lifespan of lithium-ion batteries, it is basically...

A regular battery, also known as a lead-acid battery, has electrodes composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The important advantages are stable voltage and affordable price; The disadvantage is frequent daily maintenance. Old style ordinary bat...

Lithium-ion battery: It is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During charging and discharging, Li+ is inserted and removed back and forth between the two electrodes: during charging, Li+...
