MultiBMS connects multiple Bluetooth battery systems, turns live electrical data into clear decisions, and adds a configurable Ride and Race performance experience for iPhone and Apple Watch.
Monitor every pack, understand every cell, create complete battery banks, and choose how live energy moves across your screen.
Voltage, current, power, charge state, capacity, temperature, cycles, and status across multiple connected packs.
Create parallel or series banks with combined totals while retaining full access to each member battery.
Minimum, maximum, delta, balancing state, weak-cell warnings, and multiple visual layouts.
Energy Rail, Orbit, and Mist make charge and discharge direction instantly understandable.
Set low pack voltage, low cell voltage, high temperature, and Watch alerts for each use case.
Four included styles and a collection of optional skins for RV, marine, industrial, racing, and custom builds.
Create profiles for e-bikes, scooters, ATVs, karts, boats, or custom machines. Choose the battery, Watch screens, sensors, lap controls, and safety thresholds that matter.

MultiBMS recognizes supported BMS protocols and clearly distinguishes directly tested families from beta support that can vary by model and firmware.
Brand names are used only to identify compatible hardware. MultiBMS is independent and is not affiliated with, certified by, sponsored by, or endorsed by any BMS manufacturer. All trademarks belong to their respective owners.
I’m looking for a small group of people with different phones, vehicles, batteries, and BMS hardware. You don’t need to be technical—clear feedback about what works and what feels confusing is just as useful.
