Trying to tune Bafang BBS02 using android app. When I try to change settings such as max amps I only get a choice of 1 to five amps, no way to select 18. It is also the same when I look at current settings such as number one that is factory set a 52% when selected it only has one to five amps as my settings choice. All of the setting have similar results in all settings screens. What is going on?
Thanks Dave
