Connecting battery packs in series increases the output voltage while keeping the capacity the same. Laptop batteries commonly have four 3. 4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh. Such a configuration is called 4s2p, meaning four cells. . Our ISO 9001-certified manufacturing facilities and IEC 62133-compliant designs ensure that every 18650 battery pack, Li-ion, lithium polymer, and LiFePO4 system delivers unmatched safety, energy density, and cycle life. In the industry, the current situation is that large-scale energy storage system often uses the series-first then parallel. . A battery PACK includes several components such as battery cells, copper busbars, nickel strips, protection boards, outer packaging, output (including connectors), insulating paper, plastic brackets, and other auxiliary materials.
