So, i'm looking here for help:
Does it make sense, to fill differential-oil in a "Ball-Diff"???

A ball differential is open, so there is nothing to fill.  In a ball differential you typically just use a silicone type grease.  Gear differentials have a housing so some of them are filled with oil, but only if they are sealed.  Most of the lower end models with gear differentials are not sealed so you just use grease.  Oil would leak out.

youre right... stupid question
i prefer bevel diffentials, because of the slip trough and the power/strength loss

I prefer gear diffs.
Most have no seals, but if you use something like 1.000.000 diff oil weight, there is almost no chace that stuff will seap out. It`s really sticky stuff that will act as lsd diff almost.
With all metal diff like the 1:14 trucks and TLT, HL which uses same diff you can cut 2-3mm long pieces of rubber band to act as lsd diff. I used to do that when I wanted semi open diff on my TLT crawlers back in the day.

i think bevel and gear diff means the same (i work with a translater, because of my semi language skills )

Yep a gear diff has bevel gears inside them so it`s the same.

I used 1000000 silicon grease into my usa1 nitro crusher and all my 1/8 nitro rc. This very hard grease help to avoid centrifugation du to the torque. I like hard diffs . And hard grease is cheaper than a torsen diff...
