The PCM NMC 07S/20A SAME PORT (SLCT) is a Protection Circuit Module (PCM) designed for lithium nickel manganese cobalt (NMC) battery packs configured in a 7-series (07S) setup. This module provides overcharge, over-discharge, overcurrent, and short-circuit protection to safeguard the battery and enhance its lifespan. It is rated for a maximum continuous current of 20A, allowing higher current flow for larger applications. The "SAME PORT" feature suggests that both charging and discharging can occur through the same port, simplifying the battery management system. The "SLCT" (selectable) feature likely refers to adjustable settings for specific battery configurations or protections.
