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 a nominal voltage around 3.7 V, giving a nominal pack voltage of about 22.2 V (6 × 3.7 V) and a full-charge voltage of 25.2 V (6 × 4.2 V). Capacity in a 6S2P pack is twice the capacity of a single cell (because two cells share each parallel group). For example, using 2500 mAh cells yields about 5 Ah total capacity, and roughly 110 Wh of energy at nominal voltage.

Applications and care. 6S2P packs are popular in radio-controlled models, drones, electric bicycles, and power tools where higher voltage and improved current handling are beneficial. A battery management system (BMS) is typically required to monitor cell voltages, balance the parallel groups, and protect against overcharge, overdischarge, and overcurrent. Proper matching of cells and safe charging practices are important to maintain performance and safety. As with any high-energy Li-ion pack, there are risks of thermal runaway if damaged or inadequately cooled, so use appropriate enclosures, connectors, and thermal management.

In summary, 6S2P delivers a balance of higher voltage and increased capacity by pairing cells in parallel within a six-cell series stack, widely used in portable power applications.
