A 7.4v lipo is probably too much for an Mp7.
A 7.4v lipo =/= A 7.4v nicd or nimh, it matches a 9.6v nimh- and the Mp7 batteries are 7.4v nimh. (Basically, you'll eventually break something- be it a gear or frying the motor; both of which you cannot replace).
If you are going with an external battery for an Mp7, go for a good old 8.4v nimh battery- or even better, try to get a custom 7.4v nimh battery pack.
