Ebike controller

[daveswin60]

Hi to all ebikers
Can anyone help
I have a 150amp sabvaton controller and when I connected it to the mqcon app the main screen is saying lack voltage in red and reads zero .yet its connected to my 72v battery and if I turn the throttle it runs .also on the lcd screen it says 74v
Any help would be appreciated
Thanks

Hi
You may be better asking this question on the endless-sphere.com forum as there are more users who will used to this type of tech than on this forum which focuses on mainstream bike company manufactured ebikes.
