Not sure, yesterday was the longest I've ever used it. Just got it for Christmas. I forgot to charge it until about 30 minutes before we went out on the water. So, it was on for the entire 1 hour ride back on just a 30 minute charge.

So far, yes.... However, when I pulled it out of the boat ramp, there was a line of scum or something running horizontal along the port side. It looked like I'd torn it. My heart sunk for a second till it wiped away and I realized what it was.
