MultiBMS

Universal Bluetooth BMS monitor. JiKong, JBD, Daly, Victron, and 6 more protocols. Real-time pack & cell data, smart alerts, multi-device fleet view, fully offline.

MultiBMS connects your phone to any Bluetooth-enabled battery management system (BMS) and shows you what your battery pack is doing — pack voltage, per-cell voltages, current draw, state of charge, temperatures, balancing activity, and more — all in one clean, fast app.

Supports 10 BMS protocols out of the box. Tested with JiKong (JK) and JBD/Xiaoxiang hardware. Other protocols are in BETA — they parse correctly per spec but haven't been verified on every brand variant. Please email support@multibms.app if you hit a mismatch.

Features: • Multi-device monitoring — connect to multiple BMSes simultaneously • Cell-voltage view with min/max/delta tracking • Smart alerts (low SOC, cell delta, temperature) • Custom groups for fleet monitoring • Skins / theme customization • Works fully offline — no account, no cloud, no tracking

Permissions: • Bluetooth — required to discover and read your BMS devices
