I have Intellicenter with the built in swg transformer. I need to replace my IC60. I see a couple aftermarket cells that say they are a direct replacement. Does anyone have any experience with them? Do the use the same internal power supply and connector I already have on Intellicenter? Do they perform the same as the Pentair units? Do they talk to Intellicenter the same so my remotes and iPhone screenlogic will still show the % setting and salt level? At about 60% the cost of Pentair, even if I don't get 9 years out of it like I got with my IC60, it may still be worth it? Thanks!
