Electrical Performance

Li-Ion and Li-polymer Battery packs must have a protection circuit module to keep Li-Ion/Polymer Battery packs from over charge, over discharge, and accidental battery explosion due to its extra high energy density. This Protection Circuit Board is specially designed for 29.6V 8 Cells Li-Ion Battery packs made of Li-ion and Li-Polymer cells.
