6 FAQs about [Inductive voltage of lithium battery]

What is the working voltage of a lithium ion battery?

A single cell of a LIB provides a working voltage of about 3.6 V, which is almost two to three times higher than that of a Ni–Cd, NiMH, and lead–acid battery cell. The LIB provides steady voltage under any load condition. It has good working performance until its reasonable discharge, i.e. successfully retains constant voltage per cell.

How many inductors & switches are in a lithium ion battery pack?
