Mosfets are strongly recommended for 9.6v nimh large cell batteries and 11.1v lipo batteries, and thats due to the voltage, not specifically the amperage.
Higher voltage causes arcing, which will dirty the trigger contacts, and a high amperage coupled with high arcing will destroy them.
You can safely run any stock gun off a 7.4v lipo, no problem.
Discharge rate is not something you need to be concerned about unless you're under the motor requirements.
So if your motor draws 15A and you supply only 10 from a lipo, big problem.
If the motor draws 15A and your 9.6v mini only supplies 3A, no big deal.
If the motor draws 15A and your lipo supplies 50,000A, no big deal.
Ive got a thread on batteries in the noob section that covers all this in detail. There are other major advantages to lipo over nimh aside from the energy density.
