A 4-cell battery generally has a higher capacity compared to batteries with fewer cells. Battery capacity measures how much energy the battery can store, typically expressed in ampere-hours (Ah) or milliampere-hours (mAh). When batteries are configured in series, like in a 4-cell setup, the voltage increases while the capacity remains the same as a single cell. In contrast, when batteries are configured in parallel, the capacity adds up while the voltage stays the same.
For example, a single lithium-ion cell provides around 3.7 volts and 2,000 mAh. A 4-cell series configuration will supply 14.8 volts (3.7V x 4) but maintain a capacity of 2,000 mAh. If you were to compare this with two cells arranged in parallel, that configuration would provide 3.7 volts and double the capacity to 4,000 mAh. However, it does not offer the same higher voltage.
In summary, a 4-cell battery offers a balance of increased voltage suitable for devices needing higher power, while the actual capacity in terms of stored energy does not surpass configurations that stack cells in parallel.
