Board seems to start wobbling at about 70% charge

My board is a lil focer v3 with a jwxr 64 volt pack with a stock fm charge only bms. It seems as though as soon as it hits around 60 volts the board starts wobbling when I’m just riding normally, it does all happen at full charge but less frequently. I’m not sure what it could be but it definitely is preventing me from riding it normally. My first though was that it could have to do with atr being to sensitive but i changed some things around and no luck. If anyone has any ideas please let me know. My next solution is buying a new battery which I’d like to not have to do.

You’re gonna have to specify what you mean by wobbling, as that term implies rolling heel to toe, which has nothing to do with the software since that’s just based on your ankles and the tire. Do you mean the nose angle is going up and down?

No idea why an issue would be specific to the battery. A screen recording of the AppUI tab, preferably with audio calling out when this feeling happens, would help reveal what could be going on. I would test on the default tune if you havent yet, no idea what kind of tune you’re on currently
