Lipo battery mod...possible?

[Panic]

Recently i purchased this saddle packs...http://www.amainhobbies.com/product_...ducts_id/32821 .
Their size is ok and they fit just fine in my Pred but the main problem is that the wires are too big/thick and they dont allow for the shell to close firmly. Everything is squeezed, wire touches the shaft etc etc. Is there any way to shorten them? or even i can change ie the plug from deans to corally bullet style so that i can save space?

Any suggestions will be welcome...thanks
