Battery Low Level Light but battery is good

New to Sea-Doo and PWCs as a whole but very long-time boater and DIYer.

Got a new 2021 FishPro...(long story but it is new..never been in the water). Anyway, powered it up without running the engine and after about 10 secs, the battery light comes on with the audible long beep. About a minute later the electronics shut completely down. Power it up with engine running and for the duration allowed to run only with the flush, the battery alarm doesn't fire. Obviously, my time to test this is very limited. Shut the engine off and everything seems like it's cleared up with the electronics on and no alarm. About a minute later, the alarm fires, and shortly after that everything is off.

Tested the battery while the engine is off and running...12.5 and 14.5 respectively so everything there appears fine. An observation I noted is when you initially turn on the electrons, you can hear a high pitch whine for a few seconds. At this point, the alarm has not fired. Then that same sound happens again for just a second then the battery alarm fires. Guessing that is the fuel injection system priming based on the approximate location of the source My Merc 8.1 Horizons did basically the same thing.

Also worth noting again, this is a new vessel...less than half an hour (was started a few times a month in the driveway). Maybe related to break-in??????

Anyway, sorry for the long post and that's all I got. Any ideas??
