Archon controller compatibility and efficiency questions.
Since the Bafang Ultra/620 has been out for a while now, I understand there have been at least two factory controller updates/revisions having to do with the rotor shaft rotation position sensing system. The earliest version used a standard 3 hall effect sensor arrangement embedded in the stator structure, while a later version uses a chip mounted on the controller circuit board to sense the position of a bar magnet placed on top of an underlying spinning shaft.
Is the Archon retrofit compatible with both arrangements or only the standard Hall triad system? I ask this because I just ordered a Sondors LX step through fat bike (based solely on a computer rendering of its high chainstay frame in much the same way I bought a Frey CC for the look of its full suspension frame) which apparently will come with the new CAN bus version of the controller/motor which may or may not have the vestigial 3 Hall sensors. For Winter riding application I was thinking I might need all the power I can get out of the motor, but even if I don’t, it’s always good to have options.
Regarding efficiency: Early on in the FREY forum it was reported by a couple of fellow CC owners that they were getting 13 to 15 or so miles on a charge using throttle only over fairly flat terrain. I see coincidentally both have ordered the upgrade, but apparently for vastly different reasons. If both could repeat their earlier range tests with the new controller under as close to the same conditions as their previous runs, it might be informative.
