My battery level was only 77/100 when the diesels finally kicked in. Ran at 2/3 (using the telegraph settings I posted in an earlier post, which gives about 10 knots) and hit the timeaccel. More than 24 hours later, the battery level was only 88/100. I ended the test.

It seems that something I read elsewhere on these forums is true, to an extent. SH4 does not seem to use the range value for submerged endurance. At least, not in the way we expect it to. My batteries should have been dead or near dead after 1500NM. I also note, that at least the RPM value for the E_Propulsion isn't used. Instead it uses the RPM value from the surfaced portion of the propulsion (which may mean it also uses the surfaced range as well, though perhaps not the speed). Either way, I had far greater range than I'd set, and while I did manage to get it recharging, it was doing so too slowly to be of any real use. Further tweaking is in order. Note also, that the surfaced range was still set at 150k NM. You may wish to check to see whether it does use the RPM value for the Peroxide engine.

Try the test again, without a Walther drive in the game files. I noticed that when I add the Walther to any of my boats my propulsion settings were off.
