A self-contained telemetry and logging system for electric motorcycles, built for the people who build and test them. It reads your BMS and charge controller directly and shows you what the pack is doing under load, on real roads. It's your data on the device, never in the cloud.
A BMS knows everything about your pack and tells you almost none of it. Usually you need a laptop, a serial terminal and a parked bike to get at it, so you learn what went wrong after the ride, if you learn at all.
Every cell in the pack as a live color-coded bar, with the weakest and strongest always marked and standard deviation tracked continuously. Packs over 24 cells draw in two rows, so a 40-cell pack fits on one screen. A cell going out of line shows up while you can still do something about it.
Works with many popular BMS, charge management and EV drive systems, with more integrations being finalized. It reads the BMS and the charger over two serial channels at once and finds them on its own, so you don't have to configure ports or open a terminal.
Every session written to CSV with GPS, altitude, speed and ambient temperature lined up against pack data, row by row. It stays on the device, never in the cloud, in a format any tool can read.
A five-zone color ramp (nominal, good, advisory, warning, critical) chosen to stay distinguishable with deuteranopia, protanopia and tritanopia. Critical is violet, so it can't be mistaken for a brake light.
Live gauges, per-cell bars, thermistors, GPS speed and altitude. Adjust BMS limits from the bike without a laptop.
Charge progress, live current and watt-hours, cell balancing, and EVCC parameters you can change mid-session.
Browse and graph any past session on the bike. Pan, zoom, compare cells, read energy use per mile.
Configure both devices, manage rider profiles, set the time and export sessions, all from the touchscreen.
You're assembling packs and choosing components, and you need to know what your choices did on the road.
Repeatable sessions, consistent logging, and a record of what the pack and charger did on every run.
Bring a bike in, plug in, and see the pack's real condition before you quote a repair. The same skills the technician course teaches, with instruments to match.
The DBB is running on bikes now, recording live rides and charges. Early-release tester units are planned at $699 for builders, testers and shops. Everyone on the waitlist saves $99, whichever DBB they choose: an early-release tester unit now, or DBB Lite, Full, Pro or Desktop when they're released. Join the waitlist, and see DBB Desktop for desktop sync and a battery health report card.
