6S2P

6S2P is a common battery pack configuration used with lithium-based cells. It means six cells are connected in series, and at each series position there are two cells connected in parallel. In total, the pack contains 12 cells arranged as six parallel pairs in a series chain.

The configuration determines both voltage and capacity. With typical Li-ion or LiPo chemistry, each cell has

Applications and care. 6S2P packs are popular in radio-controlled models, drones, electric bicycles, and power tools

In summary, 6S2P delivers a balance of higher voltage and increased capacity by pairing cells in parallel
