Customer ServiceLithium 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.
In this blog, series and parallel configurations of lithium batteries are discussed. By configuring these several cells in series we get desired operating voltage. Also the Parallel connection of these cells increase the capacity which directly increase the total ampere-hour (Ah) rating of the battery pack.
When designing a lithium battery pack, engineers have two primary options: connecting individual cells directly in parallel or connecting strings of cells in parallel. Each approach has its advantages and disadvantages, and the choice depends on the specific application needs and design goals.
Lithium batteries are connected in series when the goal is to increase the nominal voltage rating of one individual lithium battery - by connecting it in series strings with at least one more of the same type and specification - to meet the nominal operating voltage of the system the batteries are being installed to support.
For example, connecting two 12V 10Ah batteries in parallel method creates a 12V 20Ah battery. This BMS parallel connection is mainly used in applications like electric vehicles, solar panels, household electronics, and boats. When lithium batteries are connected in parallel, the voltage remains the same, and the battery capacity increases.
There's no problem in putting lithium cells in parallel as long as they're similar, if you charge them in parallel they'll equalize, when you discharge them in parallel they'll discharge at approximately the same rate. Usually what leads to issues is unregulated lithium cells being charged and discharged in a series.
