Series Voltage Calculator
Calculate the total voltage from cells connected in series. Add individual cell voltages or quickly compute identical cells stacked together.
e.g. AA = 1.5V, Li-ion = 3.7V, Lead-acid = 12V
Enter the total number of cells in series

V
4 × 1.5V = 6.00V
Formula
For cells connected in series, the total voltage is the algebraic sum of the individual cell voltages:
Vtotal = V1 + V2 + V3 + ... + Vn
? Frequently Asked Questions
How do you calculate total voltage of cells in series?
Add the voltage of each cell together. For cells in series: V_total = V1 + V2 + V3 + ... + Vn. For example, three 1.5V AA batteries in series give 4.5V total.
Does connecting batteries in series increase voltage or current?
Connecting batteries in series increases the total voltage while the current (capacity) remains the same as a single cell. This is useful for powering devices that need higher voltage.
Can I connect batteries with different voltages in series?
Yes, you can connect batteries with different voltages in series. The total voltage is simply the sum of their individual voltages. However, mixing different chemistries or capacities is generally not recommended for long-term reliability.
