Since you told me about that in your last PM I took a look. In the .sim file there's a controller called unit_submarine which has fields for ranges. I understand that changing the range for submerged range will do it.

Currently the submerged range is entered as 96 miles (nautical miles I guess) at 2 knots. Wikipedia lists an underwater range of 48 hours at 2.5 knots for the T-class boats, which equals to 120 nautical miles at 2.5 knots.

Wiki also states that at the maximum underwater speed of 9 knots batteries would last just 1 hour. You could test those values and see if this max speed endurance is also close.

Hope this helps

I noted that same info about the 2.5 knots @ 48 hours run time... just was sitting here, trying to figure out the range limits those figures would translate down to... so yeah, that does help.

Now, the next thing to look at, is figuring out... just how to get into that particular file, to cross check the setting there.

Will see of running a test at 2.5 knots submerged & then for a full bore run at 9 knots... & see what the time value is, if it comes close or misses that info marks, on those speeds.

Thanks for the info.

You will have to do quite a bit of "testing" (which can be fun), and not just of the battery drain, but also the re-charge rate as well as other aspects. All of the sim settings seem to "bleed" into other seemingly unrelated settings and affect those a bit also.

Good question there... which also led Me to consider & ponder... if after testing just as a base rate... drainage at 2.5 knots submerged...

if after that testing & the follow up, of doing a test run @ 9 knots submerged... & the end results are matching or as close to those of the source info... if perhaps the speed settings for the tele, may not got gotten skewed...

will also see of testing that & seeing what the top speed is after giving the 1/3 ahead order...

What led to all this was.. I gave the 1/3 ahead order & had the batteries drained out after only 8-9 hours run time, submerged. Which, being used to the... U.S. (& of course... the Uboat arm of subs as well... :yep) of batteries NOT draining out, nowhere near that fast.

Only thing I can contemplate as being the... likely culprit, is either the battery file controls or... on retrospect, the speed settings... 1 or the other.. unless there is more than just those 2 areas.

Hmmm...

Curiouser... & curiouser...

Did 2 tests, (submerged, no less ) & found the oddest end results... which I shall out line.

Test 1:

Before engaging engines... I brought the sub to a complete halt. No forward motion.. submerged & proceeded to order 1/3 ahead...

In the attached snap, note the speed registered on the telegraph...



Boats, kicking close to 4 knots on the tele... what is curious.. is.. & noted, when I gave the order further on.. to engage going 9 knots... is that I had to click on the tele... .5 knots faster, to get the Helmsman(?)/Chief(?) of the boat, to confirm the order given... of 9 knots forward motion. This also held true on the .5 knot extra, on the tele... when I gave & got confirm from the Helmsman(?)/Chief(?) of the boat, to confirm the order given, to go 2.5 knots ahead... strange.

Can't recall when tooling about in either the Uboats or the U.S. boats, of having to do so... at least, NOT that I can recall of here.

Strange fact # 2....

On running a full bore speed run... submerged, no less... boat took to 9 knots, reported on confirm (same conditions as outlined above, of a .5 additional click on the tele... ) of the boat taking to the commands... until the battery got drained down to 50%... after that point, the speed kept dropping, despite My repeated clicking on the tele.. ordering for 9 knots. At this time, had run submerged at full bore.. for about an hour... hour & a half... end result was batteries drained down to 30-35% remaining charge left.

At this point... am unsure of or unclear... as to what would need to be done, to get that set of oddities, ironed out.

The SubName.cfg in the Submarine folder has the settings for the Ahead 1/3, etc., by the use of the decimal fractions (my brain seems to tell me that one of those is backwards - Slow??)... those are for surfaced & submerged.

Usually speaking, if you get odd behavior from the crew though, it can be anything from improper attire for your crew (seriously - misspell anything for the crew, and they go blind and cannot comply - strange), to something similar being misconfigured with the equipment, so you do have to double-check everything. In CMN some time ago, I changed something, and then the sub would not move until I submerged, and then it was fine... s7rikeback found that one, but I do not recall what exactly it was... A mind is a terrible thing to allow to grow old...

All I can add here is the obvious, it is a real pain in the...stern. lol

In TMO I am quite happy with engines, fuel, performance, ducimus did an excellent job, so have not tweaked it much but did play around with settings out of curiosity and to learn some thing. I feel for anyone trying to really tackle these issues. lol

as PB said, a mind is a terrible thing to grow old.
when i read this thread at first, i read battery but processed oxygen.
don't ask me why.

so, back to the topic of battery usage, yes, the .SIM file for the boat controls the battery charge but NOT the re-charge.
recharging is a function of engine use on the surface and is hard-coded.
battery life is function of range and speed. SH4 will take the values input into the .SIM and calculate the battery charge for your boat. the greater the range and speed, the more battery life you will have. also, if you enable Special Abilities, there are some specials that will extend the battery life even more.

have i experimented with this feature? yes, i have. have i come up with a magical set of values. no, i have not.

propbeanie, ol' chap... Thanks for that tid bit of info...

Was enough there, for Me to crack the issue & resolve it, close enough that it's better than what it started off as.

To every one else, I appreciate your taking the time to chime in... warmest regards for that.. it is very much appreciated.

Excellent! Glad you have found the ballpark and are able to knock it out of there!!! or at least got a triple with a couple RBI...
