Recently my yarbo has not been charging above 76% it charges just fine to that point but then stops, being set at 80% for resume is obviously not working. Connection to battery is good, I did clean it with electrical cleaner and put dielectric grease on it when I put it back together. Still having the same issue.

Unplug the battery for 4 hours minimum to reset the BMS. Plug it back in and let it charge up to 100%. If it continues to have trouble, put a ticket in and they can update the battery firmware to solve the issue or diagnose if it is a bad battery.

Yep, I parked it on the charger, set to charge. Then unplugged the battery, got caught up working on things and it was 24 hours before I got it plugged back in. It instantly showed 100% and has not had any issues since 👍
