Pleasure to help, after reading many of your useful posts its good to return the favour

Just note that as its SCR based your likely to get the peak of the mains voltage on your batteries so if your on 110v AC that is 156v. If you had just measured the 80v with a multimeter in DC mode it may be off for 1/3 of the time and rectified mains for the rest of the time so it may have gone up to 156v. The battery may smooth this out for you but it may cause you some issues.
