Hey All, my V10f has been pretty solid since purchase, in 2021. I've done 702km on it.  It's been sat for a few days then this afternoon I heard a beeping coming from somewhere and traced it to the V10f. It's less of a beeping and more a gentle ding every 3-4 secs and the brake light is pulsing/flashing every second.  This is all while powered off. 

It turns on OK, connects to the app(s) and maintains it balance but it won't charge. Multimeter says 84.1 V at the charger pins, but there is no reaction when I plug the connector to the wheels charge port. 

Anyone experienced this before? Any suggestions as what the cause might be? I think I'll be spending the next few evenings taking it apart to disconnect the battery and check cabling etc.

Thanks in advance.

Beeps/Light show - no idea.

How empty is the wheel? %%%

Are you doing anything out of routine while trying to charge? Something different as usually..

Ref battery, it's at about 10%. I've never run it down this low. I arrived home at 37%. Forgot to charge it till late that evening so it had about an hour on charge. Got home the following evening and it was just below 40% again. About right for the journeys I'd done.

Today, went to charge it and nothing. Turned it on, battery level is at 10%. I think something has been draining the battery since I last used it (Thursday).

Nothing has changed otherwise.

Try this - go for a little (very little ride use ~2% battery at most.) And right as you get home - try charging. (No dressing down, or getting a drink - right for charger!)

It's very low, but still should charge..

 

Flashing and beeps probably was LOW battery warning system now thinking.. As it was right at 10%..

I took it out for ride yesterday eve, battery reported 9%. I rode about 20 meters before the wheel tilted back to the point I had to step off. I probably didn't even hit 10mph. 

I had to walk it back so didn't exactly get it on the charger instantly after the ride. Suffice to say it's still not charging, or showing any indication of charging.

I manged to stop the recurring dings (4 dings, then a pause and repeat) by simply disabling audio in the app. The brake light pulsing stopped after the test ride. Maybe battery too low? The Inmotion apps reports 8%, EUC World reports 0%...  

Was thinking new sys board but it's pricey and doesn't actually include the "charging" board, which i couldn't even find on SpeedyFeet, so I'll opt for some charger testing instead. I'll place a dummy load on it and confirm current is flowing...
