EG4-6500 switch from battery to utility

Maybe they didn't think it was important. Because they would rather everyone use communications, and work with settings based on %. But I prefer voltage for these settings.
Surface voltage fluctuates more based on current flowing. If the sun rises strong, i switch back to battery sooner. If it's cloudy, I switch later in the morning. This avoids short cycling Because of trying to narrow the range with settings based on %.
Well it took a while and I finally got EG4 battery comms working. Then I flashed the EG4 batteries to the latest firmware and BLAM no more battery comms. After screwing around trying to again get battery comms working again I told myself screw it and changed over to voltage for battery control like so many others.
