Product Description
LT-14S009 | 13S/14S Wire‑Free BMS
30A Continuous Discharge | 48V/52V Li‑ion | Dual NTC | E‑Switch
The LT-14S009 Battery Management System (BMS) is an innovative, wire‑free solution designed for 13S (48V) and 14S (52V) lithium‑ion battery packs commonly used in electric bicycles. Featuring common ports for charging and discharging, a wire‑free design that simplifies installation, and 30A continuous discharge capability, it delivers exceptional performance, safety, and convenience. With dual NTC thermal sensors, an E‑switch, and comprehensive protections (over‑charge, over‑discharge, over‑current, over‑temperature, short circuit), this BMS ensures reliable operation and extends battery lifespan.
📡 Key Features
🔋 Wire‑Free Design
