Smart BMS Bluetooth Module UART BLE001 V1.2

The BLE001 V1.2 is the official external Bluetooth Low Energy (BLE) communication module for JBD / Jiabaida Smart BMS boards, enabling full wireless monitoring and configuration of your lithium battery pack directly from your smartphone — no PC, no cables, no display hardware required.

Connecting via the 4-pin XH2.55 UART port found on compatible JBD Smart BMS boards, the module pairs instantly with the free XiaoxiangElectric app (available on both iOS and Android) to deliver real-time visibility of individual cell voltages, total pack voltage, charge/discharge current, state of charge (SOC), temperature readings, cycle count, and active protection status. Beyond monitoring, the app also allows you to adjust BMS parameters such as protection thresholds and balancing settings remotely.

Compatible with Smart BMS configurations from 3S to 30S — covering both Li-ion (3.7V) and LiFePO4 (3.2V) battery chemistries this module is the simplest and most cost-effective way to add wireless intelligence to any compatible JBD BMS build. It ships with a pre-attached communication line for plug-and-play installation. Ideal for DIY battery packs, solar energy storage, e-bikes, electric vehicles, and home power systems.

Note: This module shares the UART port with any LCD display accessory, both cannot be connected simultaneously.
