Default Using large 7.4 volt NIMH packs in Truggy that uses 9.6 volt LiPO or Li-ion

I bought my son and I two fx S911 truly cars from GP toys..They are 9.6 volt battery packs...Would it be safe to use my old 7.4 NIMH packs in them. What benefits and disadvantages would I see?

Yes you could use NiMh packs. Speed would be reduced a bit. Just turn off any LVC on your speed control.

Two questions:

Would the LVC help protect the NiMH battery also? What benefit does turning it off serve?

How does one turn off the LVC?

No, LVC would not work with nimh batteries as far as I know. I can't seem to find that car online, it might not have a LVC. A LVC is only used with lipos, so if you previously only used it with nicads, it is already off. A LVC is a cutoff that prevents lipos from being over discharged.

Well, maybe, Li-ion is a pretty generic term.... Check the manual and see it there is any mention of a ESC (electronic speed control). If not, then the esc is probably not programmable. You can also take the body off, try to find the esc and see what esc it is. That way you can look it up, and see if it has a LVC. A LVC would likely be ueful to a li-ion

If it was a lithium battery though, then speed may be decreased alot with a 7.4 nimh. Question, does it say 7.4 volts on your nimh battery? It shouldn't. What does it say on the lithium battery inside? Again, it should not say 9.6 volts.
