Electric Brushless Controller 48V-72V 1000W-1500W 12 Tube Dual Mode Speed Motor Controller for E-Bike Electric Scoote

So far works well but very confusing wthout a good translation of connection details
I’m liking it so far, despite working completely blind; without any accurately translated descriptions of the wiring connections. For example, ‘Jog tree speed’ and ‘Shift tree speed’?! – presumably relates to ‘3 speed’ generally? Which sounds pretty essential considering that PAS does not appear to be included, unless PAS is supported in some way that is not familiar to me? (only ‘Throttle’ is clearly stated as being supported, using ‘Cruise control’ and or ‘3 speed’ etc., perhaps?). Also, the ‘Jog tree speed’ connector does not appear on the pictures of the connections anyway, so this is your actual ‘Chinese puzzle’. However, I think that I have everything got enough features working to get by initially… That said, someone else posted that his unit was set at 72v instead 48v and so they opened it and set a jumper? I cannot see any jumpers relating to that myself. Any sharing of advice would be greatly appreciated. Google Lens is the best way to try and make sense of the labels when you translate photos of them to your language. But I have still been able to figure out how to use 3 Speed so far. Steve.
