I had my Shorai in when we went across deep water crossing in Wyoming (remember forever west 2011) with no issues. Was in torrential downpours in Pacific Northwest when we thought the bikes were going to float away.
Battery has been completely soaked or underwater (since it sits so low on the 950) many times with no issues so far.
