House battery problem - is it me or Interstate?

I use my Renogy solar 100 watt suitcase to get the higher volts needed to top charge my Interstate's. Which controller do you have coming with your flex panels? Hope you are getting this one, Viewstar 20 amp the cheaper one doesn't have equalization. I set my equalization mode up to 16.3 volts and the boost charge to 15.4 volts. PM me if you want to know how to do it, it's a special way of setting the parameters that Renogy told me.
