Batteries in Series

Back to Glossary

Batteries in series are when the cells are electrically wired together in a chain where each positive terminal is connected to the next cell’s negative terminal. The resulting capacity remains the same, and the voltages are added together. Multiple small battery cells wired in series are functionally equivalent to a higher voltage battery of the same capacity. The weakest battery in a series string limits the performance of the entire string.
