New member here from Denver, CO with a Ninebot ES4
 

Just getting the ES4 broken in now, happy to be here.

What brought me here is the error code 10 (dash communication error) - and I think I might be figuring out some causes of it due to the app disconnecting during charge cycle when it's charged while bluetooth connected to the app. More testing to come but the last time it happened I did NOT have to disconnect the handlebars and re-connect the wiring, as it sorted itself once I restarted the charge cycle without the app connected. More to come there!
