Charging Issue

Hey Everyone!!

My charger keeps telling me it's done way before the battery actually is. I plug it in and the LED goes red like normal, but then it flips to green before the battery hits 100%. If I unplug it and plug it back in, it goes red again and keeps charging. I can eventually get it to a true 100% just by doing that over and over and sometimes I don't have to do it at all and will charge to 100% on it's own.

Happens whether the battery is in the bike or off charging by itself. I've also run it all the way down to 0% with no weird behavior on that end, so it seems like the battery itself is fine with taking and holding a charge, it's just the charger cutting out early and reporting done when it's not.

No error codes on the display when this happens. Tried a different outlets too, same result.

Really hoping this is just a flaky charger and not something wrong with the battery or BMS. Has anyone run into this? Did a new charger fix it, or did you end up needing a battery/connector swap? Trying to figure out what to expect before I deal with Specialized support.
