450 / 570 Snorkel Question

I have a 2016 570 EPS and a 2016 450 HO EPS. I was thinking of getting a snorkel kit. I’ve never done this before. So, this is a newb question:

With the battery so low in the machine..does it do any good to snorkel? I know I could raise the intakes, but can your battery survive being submerged? I know its in a case…but it it would seem like water would get in.
