Product Description
EMB16S003 | 16S 48V 40A CAN/RS485 Smart BMS
For Li‑ion / LiFePO₄ Batteries | 7S‑16S | CAN & RS485 | AFE TI BQ Series + MCU
The EMB16S003 is a versatile smart Battery Management System (BMS) designed for 7S to 16S lithium‑ion and LiFePO₄ battery packs, covering nominal voltages from 24V to 48V (and up to 60V with 16S). With 40A continuous discharge current, dual communication interfaces (CAN and RS485), and advanced AFE TI BQ Series + MCU architecture, it delivers precise monitoring, robust protection, and flexible system integration. Ideal for e‑bikes, energy storage systems (ESS), electric vehicles, and industrial battery packs, this BMS includes SOC/SOH fuel gauging, adjustable parameters, E‑switch, sleep mode, and comprehensive fault protections.
📡 General Info
The EMB16S003 BMS is a high‑performance, software‑configurable solution supporting 7S to 16S Li‑ion or LiFePO₄ cells. It features CAN (Controller Area Network) and RS485 communication interfaces, enabling real‑time monitoring of battery voltage, current, capacity (SOC), and health (SOH) via external displays, vehicle controllers, or central monitoring systems. The compact 146mm × 80mm form factor allows easy integration into battery enclosures for e‑bikes, energy storage racks, and other space‑constrained applications.
