I dunno what yur battery looks like, but here in the rain forest mine frequently gets wet riding.
My batteries are of the dorado type. The only part I worry about is water reaching the connection
points. If RCS means a Rip Current S, your have the dorado type also. I don´t think you need to
panic unless you found moisture in the connection. That has happened, but when it does the
battery will short out & fry the connection. You should be okay.
P.S. I alway remove the battery after a ride, itś a good idea. When transporting on my rack,
the battery remains in the vehicle, & I put duck tape over the connector to keep it dry, as I
have often travelled in the rain. You´d pretty much have to completely immerse that battery to
damage it. Check to see if the fuses got wet too....Oh, be sure to remove tape b4 installing
battery. Not doing so can lead to momentary panic when the bike doesn´t turn on.
