Battery type 'SLD'.
After playing with the controller and attempting to change charge voltages I contacted Grape.
'Thanks for getting in touch. The charging voltages cannot be changed on this controller. The app enables other settings to be altered (such as EQ cycle time, battery capacity, etc.), but the charging voltages are tied to the specific battery type settings. The only voltage settings that can be adjusted are the two "over-discharge" values. Please let me know if you have any other questions.'
I sure thought in the past I was able to change more, I know I had changed ABS time from 120 to 180 mins but several attempts the last several days and I can't seem to get much to change/save.
I use the load feature and have changed those settings via the app.
