I ordered a BBS02 kit with 13.5ah 48V battery as part of Lunacycle's anniversary sale and installed it on a cheap front suspension 700C bike. It was a dream for a few weeks but now the system is cutting off much sooner than I would expect. I was easily completing my 12 mile commute every day with the battery going down to 46-48V from 52.5V (85% charge). Now as soon as I get to 49V everything shuts off instantly. The screen turns off and there's no power until I disconnect and reset the battery in the cradle. If I do that, everything comes back but only temporarily until it cuts off again.
This happens every day at pretty much same same place on my return commute. It's a flat paved shared use path so it has nothing to do with loose connections. I end up pedaling back home without any assist and when i check the voltage on the battery it is always between 49.0V and 49.3V. It's too consistent and predictable for me to think that it's due to a loose connection. The controller and motor come back to life as soon as I charge back to 85% so I can't see this being an issue with a blown controller.
I checked the programming on my controller to check the Low Battery Protect and it's set to 39.5V, the lowest setting allowed. Limited Current is set to 18A and Designated Assist is set to 8 in the throttle settings.
After a week of runaround from Luna and no luck fixing it on my own I feel like I'm SOL and the only way forward is to buy another battery and motor to eliminate possibilities but that feels like throwing good money after bad. I'm really disappointed with the QC and customer service from Luna right now. Does anyone have any ideas what could be causing this? Ways to diagnose the cause?
