7.4V Lithium Polymer Battery Pack for Smart Door Lock｜B‑End Product Introduction
Product Overview
Professional 7.4V lithium polymer battery packs specially designed for smart door locks. Assembled with 2‑series soft‑pack cells, tailored for fingerprint locks, password locks, hotel intelligent door locks and access‑control locks.
The battery delivers stable pulse discharge output to drive lock‑unlocking motor. With ultra‑low self‑discharge performance, it supports long‑term standby for smart lock equipment. All cells are Grade‑A pouch cells with strict sorting on capacity and internal resistance. Equipped with dedicated protection circuit module to prevent over‑charge, over‑discharge, over‑current and short‑circuit. It restrains lithium dendrite growth, effectively avoiding swelling and potential safety hazards during long‑time standby. Factory direct supply, full OEM & ODM customization for smart lock manufacturers.
