It looks like the motor max rpm is roughly 135. Set this setting to your wheel diameter, if your wheel diameter isnt in the list, then select the one that is closest to your wheel diameter. You are also addressing the fact that you cant keep up with the motor at high power levels due to the high rpm. But as explained in the previous comment, the 36V battery will not work with the BBSHD. stc-isp-15xx-v6.86E.zip The controller and cooling of the BBSHD are better than the BBS02. Et aussi ce forum https://forum.velotaf.com/topic/28285-programmation-kit-moteur-pedalier-bafang-bbs/. Almost all functionality of original firmware has been implemented and additional features have been added. So you can absolutely only change the current limit and have the same recommended settings for the BBSHD.

But this way you can have PAS 1 as the no power setting on startup as a safety feature. You then multiply the voltages with 13 to get the voltages for a 48V battery. Try a different pc, different cable, different order of connecting to the controller, etc. This can be convenient if you have parked the bike and want to show someone something. With 12-14Ah, you could have some range anxiety ;p. The BBS02 750W will have more than enough power for you needs, the BBSHD definitely isnt necessary. Whats the point?

Max current: 28A, If 28A is written on the controller, this will be the maximum. . There are three things you can do to improve the pedal frequency (cadence) at high speeds: Get a bigger front chainring.
