2s1p鋰電池是什麼意思

"2s1p" is a term used to describe a configuration of lithium-ion batteries, where "s" stands for series and "p" stands for parallel. In this context, "2s" means two batteries connected in series, and "1p" means one battery connected in parallel.

Here's what each part of the term means:

• "2s": This indicates that there are two batteries connected in series. When batteries are connected in series, the positive terminal of one battery is connected to the negative terminal of the next battery. This increases the overall voltage of the battery pack, but the capacity (measured in ampere-hours, Ah) remains the same as a single battery.

• "1p": This indicates that there is one battery connected in parallel. When batteries are connected in parallel, the positive terminals of all batteries are connected together, and the negative terminals are connected together. This increases the overall capacity of the battery pack without affecting the voltage.

So, a 2s1p lithium-ion battery pack consists of two batteries connected in series, with no batteries connected in parallel. This configuration results in a higher voltage (since the voltage of each battery is added) but the same capacity as a single battery.
