What is the approximate nominal voltage of a LiPo battery cell?

• A. 1.5 V
• B. 2.0 V
• C. 4.2 V
• D. 3.7 V

Answer: (D)

LiPo cells operate with a typical voltage around 3.7 volts per cell. This nominal value acts as a standard reference for estimating pack voltage and overall performance because, in regular use, the cell spends most of its life around this level. The voltage actually climbs to about 4.2 volts when the cell is fully charged and drops toward about 3.0 volts as it discharges. Using 4.2 volts would describe the maximum charge, not the average operating level, while 1.5 or 2.0 volts would be far below normal operating range and not representative of a healthy LiPo cell. So the best approximate nominal voltage per LiPo cell is 3.7 V.
