I'm about to build me a serial cable this weekend and do some battery testing.
Anybody still have a copy of the old terminal.exe program? I can't find it at pro-trak's site anymore. I'm wondering whether the new programs by Kiyano will work with an older Pro-track. My non-upgraded unit looks like the one in the picture below. It does not have the mulit-phase charging. I keep forgetting to take not of the exact version number.
