A self-contained telemetry and logging system for electric motorcycles, built for the people who actually build and test them. It reads your BMS and charge controller directly, shows you what the pack is doing while you ride, and writes every second of it to a file you own.
A BMS knows everything about your pack and tells you almost none of it. The usual answer is a laptop, a serial terminal and a parked bike — which means you find out what went wrong after the ride, if you find out at all.
Up to 24 cells as a live color-coded bar, with the weakest and strongest always marked and standard deviation tracked continuously. A cell going out of line shows up while you can still do something about it.
Reads the Dilithium BMS and EVCC charge controller over two serial channels simultaneously, discovering them on its own. No port configuration, no terminal.
Every session written to CSV with GPS, altitude, speed and ambient temperature correlated against pack data, row by row. It is your file, on your storage, 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, never red, so it never competes with brand or brake lights.
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 time, export sessions — all from the touchscreen.
You are assembling packs and choosing components, and you need to know what your decisions did — not what the spec sheet claimed.
Repeatable sessions, consistent logging, and a record of exactly 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. A limited number of units are going out to builders, testers and shops ahead of general release. Join the list, or step up to DBB Pro for satellite, 5G and 10 DOF motion data.
