No, I didn't feel the need to.Do own a battery backup? Did yours come with 2 cables to connect 2 other eco tech products?
But I still stand by my statement.
I think you are out of line asking for free products from a company just because you bought into the line.
The battery backup was developed for the VorTech pumps, long before the Vectra and now Ecotech has made it possible to use with the Vectras.
That's my opinion and I am entitled to it.
