Kilometers are now supported throughout MultiBMS. Choose Miles or Kilometers in Settings > Display. Speed uses km/h, distance uses km, elevation uses meters, and efficiency uses Wh/km across live Dyno screens, saved runs, replays, charts, reports, shared cards, and CSV exports. Lowest-cell readings now include the cell number and voltage unit.

Battery Storage is here — built for the moment you put your batteries away for winter or long-term storage. Put one pack or an entire bank into storage and MultiBMS captures a detailed baseline: state of charge, pack and cell voltages, temperatures, cycles, capacity, balancing, protections, firmware and more. Reconnect later to take another reading, compare any two snapshots side by side and spot cells that have drifted before they become a problem. MultiBMS now recognizes whether each reading was taken at rest, charging or discharging. It can flag unexpected charge loss, clearly show when a pack gained charge in storage, save a final reading when storage ends and export your full history to CSV. Bank-level controls make it easy to store remaining packs or bring the whole bank back into service. Also new: • Five full app skins: Bus Life, Off Grid, Marine, Hypercar and Gridline Racing • Four state-of-charge gauge styles: Precision, Segmented, Dual Ring and Original • A cleaner dashboard that fades the charging/discharging bar when the bank is idle • More accurate group current handling when a pack cannot report current • Clearer capacity, gauge-layout and storage-status messages • Reliability fixes and polish throughout Your batteries may sit still for months. Now you can know exactly how they held up.

Apple Watch reliability Recording from your wrist is solid now. Start a run, swipe between screens, stop it - everything stays where you put it. Stop means stop. Ending a run on any screen ends it everywhere. On your phone Press record and the screen goes straight to the live dyno panel instead of leaving you to scroll for it. Also fixed a rare crash when a battery reported a bad temperature reading. You may see a few old empty recordings from before this update. Those are safe to delete.

The Apple Watch app no longer closes when you start or stop a recording. Time was being stored in a number too small to hold it, which stopped the app dead. Fixed. Swiping between Watch pages no longer throws you back to the Dyno screen, and Stop now stays stopped. The ride page was quietly starting a new recording every time the Watch redrew it, which ended the run in progress and left it marked INTERRUPTED. If you have old runs tagged INTERRUPTED with a 0:00 duration, those are leftovers and safe to delete. Race Control and the ride page now end together with everything else. Stopping a run anywhere stops it everywhere. Press record on the phone and the screen scrolls to the live dyno panel on its own. A bad temperature reading from a BMS can no longer take the app down.

This update focuses on real-world battery monitoring, Apple Watch reliability, and multi-pack systems. • Apple Watch now opens as a battery monitor first, with ride screens available when you want them. • Watch telemetry uses live iPhone-connected BMS/group data instead of placeholder values. • Improved group charging/discharging math for mixed pack states using net current and power. • Added ANT BMS connection improvements, including support for custom device names and multiple ANT units. • Added RX heartbeat diagnostics so testers can see whether live packets are arriving. • Added support groundwork and compatibility notes for Victron RV Bluetooth requests where available public protocol access permits it. • Fixed build/export metadata so the iPhone and Watch companion use the same build number. • Added no non-exempt encryption metadata so App Store Connect should no longer ask the encryption question every upload. • Improved Bus Life skin work and safeguards for one-pack and larger multi-pack layouts. • General Bluetooth, Watch sync, Skin Store, and stability cleanup.

Build 38 makes mixed battery banks and the Skin Store substantially better. • Parallel and series groups now use signed net current and power. When one pack charges while another discharges, the group status, value, color, animation direction, and Apple Watch display all follow the bank's actual net flow. • Near-zero current now settles to Idle instead of flickering between charge and discharge. • Every Skin Store item now shows readable Dashboard, Group, and Battery previews instead of generic lines and dots. • Store cards and full previews share the same renderer, so the preview cannot drift away from the purchased appearance. • All 15 styles have distinct visual chrome, including Bus Life, Off Grid, Industrial Gold, Emergency, Marine, Aviation, Retro Terminal, Arctic Ice, Matrix Code, Minimal White, and E-Bike Rally. • Apple Watch battery monitoring keeps the selected source pinned, transitions more smoothly between packs, and uses only current live telemetry—never preview values. • Compatibility and privacy wording is clearer, including optional one-time cosmetic skin purchases.

MultiBMS 1.0.6 makes the Apple Watch companion fully live and dependable. Watch screens now use the currently selected battery or group, reject stale telemetry, and stay consistent with the iPhone. Use Battery Monitor mode without a ride profile, or configure activity profiles for GPS speed and top speed, distance and efficiency, G-force, laps, BMS temperature, cell health, and alerts. This release also refreshes every Watch screen, improves Bluetooth recovery and switching between saved BMS devices, expands protocol support, and fixes startup stability.

A completely upgraded Apple Watch experience is here. Record rides directly from every Watch screen while viewing live voltage, current, power, state of charge, GPS speed, G-force, temperature, and elevation. New live curves synchronize current, speed, and G-force, while the session screen tracks top speed and peak G. On iPhone, choose which channels to record, review saved sessions, compare electrical and ride data on smooth multi-line graphs, and scrub through the complete timeline. This update also improves pack-detail layouts, group icons, multi-pack cell identity, stability, and App Store compatibility.

Apple Watch is now live. Choose Ride Profiles, batteries, Watch pages, BMS-temperature and voltage alerts, and Race/Ride metrics, then view live telemetry relayed securely from your paired iPhone. Race and Ride sessions now include detailed session and per-lap voltage drop, lowest voltage, peak current and power, temperature, weakest-cell, cell delta, and energy metrics. This update also adds reusable profiles for e-bikes, scooters, ATVs, karts, boats, and custom builds; current-responsive charging and discharging visuals; a clearer Watch setup path in Settings; expanded BMS protocol support; and improved ANT compatibility. MultiBMS is built by a hobbyist for hobbyists. Bug reports and feature requests are always welcome at support@multibms.com.

A completely redesigned dashboard makes groups, packs, and every cell easier to read. New charging and discharging effects show live direction, current, and power, with animation speed that responds to amperage. Create parallel or series battery groups and see combined voltage, current, power, capacity, cell health, and individual pack detail in one place. Rated-capacity controls, multi-pack connections, reconnection, alerts, support tools, and first-launch guidance have also been improved. This update introduces an Apple Watch companion preview with Fleet, Cells, alerts, and Race Mode screens. Builders and racing enthusiasts can explore laps, voltage drop, peak current and power, temperature, weakest-cell, energy, and session summaries. Watch telemetry is clearly labeled demo data in this release; live Watch synchronization is coming next. MultiBMS is actively developed. If you find an issue or have a feature idea, please contact support@multibms.com—every message is reviewed.

Redesigned dashboard, battery cards, group views, and cell analysis. Improved automatic reconnection for multiple JBD/Xiaoxiang packs. Capacity now shows remaining versus configured amp-hours and flags inconsistent pack settings. High-cell imbalance alerts and per-cell voltage displays are clearer, with improved pairing and password errors.
