This battery series voltage reference table shows the total voltage for a range of number of cells values, assuming a voltage per cell of 3.7 V. Every figure is computed with the same engine that powers our Battery Series Voltage Calculator, so the numbers are exact.
| Number of cells | Total voltage |
|---|---|
| 1 | 3.70 |
| 2 | 7.40 |
| 3 | 11.10 |
| 4 | 14.80 |
| 6 | 22.20 |
| 8 | 29.60 |
| 12 | 44.40 |
| 20 | 74.00 |
| 28 | 103.60 |
| 40 | 148.00 |
How to use this table
Find the row closest to your number of cells and read across to the total voltage. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Battery Series Voltage Calculator for a precise answer.
Need a value that is not in the table? — the Battery Series Voltage Calculator does it instantly, for free, with the formula and a worked example built in.
