Yup, it's okay!
G84P+Vulture2, as Darkfury mentioned, is an alternative to G91+V2. 84P provides more energy but is heavier and has less capacity. 84P can be tuned to something like (6,0,4) or (5,0,5) or (4,0,6). The tricky thing about G84P though is that it has a very small redzone, which, if you're not careful, will put you in the charging state. In most instances, G91+V2 is preferred.
EDIT:
Another thing to note is that there are only 2 factors affecting the rate at which your energy goes down when you boost:
1. Booster's charge drain
2. Total energy capacity of the generator (EC optional adds to this)
Energy supply only affects how quickly your energy bar gets refilled.
