So far, all the displays came from APT, now Bafang produces the DPC18 itself, and says:

Intelligent battery level indication: With an optimization algorithm, a stable display of the battery level is ensured, and the problem of fluctuant battery level indication common with other displays is avoided. The user can define display mode of battery level as voltage or percentage.

There are different firmwares, the older with 5 levels fixed and mode ECO and SPORT (which makes little difference)

or the new version with selectable levels, but without mode ECO and SPORT, which you get here
