Description
MultiBMS connects your iPhone to Bluetooth-enabled battery management systems and shows what your batteries are doing—pack voltage, individual cell voltages, current, power, state of charge, temperature, balancing activity, capacity, and history—in one clean app.
MONITOR EVERY BATTERY
Connect to multiple compatible BMS devices simultaneously. Open any individual pack for detailed diagnostics, cell health, balancing status, temperature, current, capacity, and recent history.
BUILD BATTERY GROUPS
Combine packs into parallel or series groups. Group dashboards use signed net current and power, so a bank with one charging pack and one discharging pack reports what the whole system is actually doing. You retain full access to every member battery and cell.
APPLE WATCH BATTERY MONITOR & RIDE RECORDING
The included Apple Watch companion opens as a focused battery monitor and can also combine live BMS telemetry with Watch GPS and motion data for e-bikes, scooters, ATVs, karts, boats, and custom activities. View live packs, groups, cells, voltage, current, power, state of charge, speed, distance, G-force, temperature, laps, and battery health from your wrist. The iPhone must remain connected to the BMS for live electrical telemetry.
SKINS THAT CHANGE THE COCKPIT
Four styles are included. Optional one-time cosmetic skin purchases add distinctive visual designs for bus life, off-grid, industrial, emergency, marine, aviation, terminal, arctic, matrix, minimal, and e-bike systems. Every item includes readable Dashboard, Group, and Battery previews before purchase. Core monitoring features and BMS protocols do not require a skin purchase.
COMPATIBILITY
JiKong and JBD/Xiaoxiang hardware have been tested directly by the developer. Twenty additional implemented protocol families are labeled BETA because battery models and firmware vary and broader hardware verification is still underway.
BUILT BY A HOBBYIST, FOR HOBBYISTS
MultiBMS is an independent passion project for builders, riders, racers, RV and solar owners, and anyone managing more than one battery. Suggestions, unusual hardware reports, and thoughtful bug reports are welcome at [email protected].
PRIVACY
Battery monitoring works offline, requires no account, contains no advertising or analytics, and does not upload battery telemetry to a MultiBMS server. Apple processes optional skin purchases. Privacy policy: https://multibms.com/privacy/
