I have had SyncUP drive for a little while now it’s always had little hiccups and it wasn’t a big deal to me but now I am continuously getting a low battery notification, and that my battery is in critical condition. I had my battery tested and there is NOTHING wrong with it, after ready a bunch of comments about others having this same issue I am 100% convinced that it is syncup drive causing this problem. I won’t be using this device anymore and I will not recommend it to anyone I know.

That's an interesting situation! An important thing to remember is that there's a whole car between the battery and the SyncUP DRIVE. And a lot of the information the SyncUP DRIVE reports to you is provided by the car; the device just lets you see it. So your best bet is to have a mechanic check it out.
I actually had this issue with SyncUP DRIVE on one of my cars, but the car was still running fine and I ignored it. Eventually, the car wouldn't start anymore and acted like the battery was dead. Bought a brand new battery but it still had the same issue. So I went to a mechanic. Turns out, the mound of powder on the battery connectors was the battery cable corroding. The mechanic had to snip off the end of the cable, put on a new connector, and suddenly everything was fine. So there are reasons outside the battery that could cause power issues.
