Frequently asked questions
Multiply the number of cells by the voltage per cell. Four 3.7 V cells in series give 14.8 V.
No. Series wiring adds voltage but keeps the same amp-hour capacity.
Parallel wiring keeps voltage the same and adds capacity.
To reach a higher voltage needed by a device than a single cell provides.
