Are series and parallel connection of lithium batteries safe?
The series and parallel connection of lithium batteries is a key technology to increase voltage and capacity, but it also contains safety risks. This article will analyze in detail the principles, methods and precautions of series and parallel connection of lithium batteries to help you avoid potential risks and build a battery system correctly.
What is a parallel lithium battery pack?

Therefore, a parallel lithium battery pack with “n” parallel batteries achieves the same charging efficiency as a single battery, with the charging current being the sum of the individual battery currents.
How to ensure safety in a parallel battery system?
To ensure safety, parallel systems must: Use batteries with consistent parameters: same model, same batch, and same capacity. Add parallel protection device: Control the mutual charging current between batteries. Make sure to connect batteries in parallel in a fully charged state: fully charge each battery individually before initial connection.
Can lithium batteries be connected in parallel?
Lithium batteries can indeed be connected in parallel, and this method is commonly used to achieve higher capacity and extend the runtime of a battery system. By connecting two or more lithium batteries with the same voltage in parallel, the resulting battery pack retains the same nominal voltage but boasts a higher Ah capacity.
What are the advantages of parallel lithium batteries?
Parallel lithium batteries have many advantages, including increased capacity, enhanced power output, and improved overall performance. When multiple batteries are connected in parallel, their individual ampere-hour (Ah) capacities add up, resulting in a higher total capacity.
Should a battery pack be paralleled?
Paralleling strings together greatly increases the complexity of managing the battery pack and should be avoided unless there is a specific reason to use this configuration. In this setup, each string must essentially be treated as its own battery pack for a variety of reasons. In a below example, 2 strings of 8 cells each are placed in parallel.
