8-20 Series 24V/72V Lithium Battery Protection Board for Two-Wheelers

Designed specifically for 8S-20S lithium battery packs in two-wheelers, this battery protection board features an advanced Battery Management System (BMS) that comprehensively safeguards battery safety and enhances performance — your ideal solution for lithium battery management.

Cloud Platform Remote Smart Management / Local Portable Assisted Operation

Technical Description:

ZB48V-0001 is an intelligent BMS protection board designed for 8–20S (24V/72V) electric two-wheeler battery applications. It supports both LiFePO₄ and NMC lithium battery chemistries, providing comprehensive battery monitoring, protection, and intelligent management functions.

The BMS integrates passive balancing technology to maintain voltage consistency between battery cells. It supports multi-dimensional monitoring of voltage, current, and temperature, with real-time alarms and protection against under-voltage, over-current, over-temperature, and low-temperature conditions. In the event of a short circuit, the system immediately disconnects the power output, and protection status can be remotely released through the cloud platform.

ZB48V-0001 features accurate battery capacity estimation based on current-time integration algorithms, enabling precise SOC/SOH calculation. After charging and discharging cycles, the system automatically updates battery capacity data to improve battery management accuracy and reliability.

With built-in RS485 + 4G communication and cloud platform support, the BMS enables remote monitoring, cloud data storage, OTA firmware upgrades, remote locking, and battery rental management functions. Users can bind batteries through the WeChat Mini Program, monitor real-time battery status, modify protection parameters, control charging/discharging switches, and remotely lock devices.

For commercial applications, the cloud platform supports battery rental, fleet scheduling, and battery lifecycle management, helping operators reduce operating costs and improve asset utilization efficiency.

For local operation, ZB48V-0001 is equipped with a button activation and reset function. The BMS can be activated by pressing the button in sleep mode, and a 5-second long press during operation allows device restart, meeting emergency maintenance requirements in field applications.

The BMS supports a continuous discharge current of 80A and a continuous charging current of 40A. It features RS485 + 4G dual communication interfaces with integrated cloud platform access. The mainboard dimensions are 136.0 × 105.0 × 26.0 mm.
