Is there a way to connect these new DC pumps with a battery backup, and still have it connected to my RKE controller ?

Tagging along because I'm curious too. I also have an RKE and am using a DC pump on my OM 4-way. I did have it plugged into a battery back up and not the RKE at first, but I would really like to do both too.
