RC Boat Vector SR65 - Large Splash all over myself!

I do love the Vector SR65 r/c boat and this is why. So controllable. First of all fast runs, just slowing for the corners. It is hitting 25mph max speed. Then I do some tights turns and it is so accurate as proven as I turn around the fountain. Then high speed runs near the side. Water is calm. Nobody near.
Then I decide to splash around. On the final splash the boat flipped and broadsided me with some water. I got drenched but you know I don't mind as it made a great shot. All part of the fun on a warm evening.

Is there an alarm function on the controller at low voltage?

Not normally but you can always attach a LiPo Meter onto the battery and use that. They are only a few quid online (eBay).
