Frequently asked questions
What voltage does this cell provide?
A Li-ion 18650 cell has a nominal voltage of 3.7 V, with a fully charged voltage of about 4.2 V. Do not run it below its minimum voltage, and use a device or circuit that accepts this range.
Can I connect two of these cells in series?
Yes, two cells in series give a nominal 7.4 V. Use a protection or balancing circuit designed for two-cell Li-ion packs, since series cells must be kept matched and protected against overcharge and over-discharge.
