Lithium battery and lead-acid battery are commonly used battery types for electric bicycles at present, and each has its own advantages and disadvantages, depending on the needs of users.

Advantages of lithium battery: Lithium battery is smaller, lighter, higher in energy density, longer in service life, higher in performance, higher in safety and superior in usability. Lithium batteries can use fewer batteries, with smaller size, lower cost, less maintenance, higher reliability and higher feasibility.

Advantages of lead-acid battery: 1. Lead-acid batteries are cheaper and cheaper, which is much more beneficial than lithium batteries. 2. Lead-acid batteries have good thermal stability, can resist temperature changes, and can maintain good performance even at high temperature.
