HB ve8 with mamba monster max: What battery?

[badass_racing]

Ive been looking at the hb ve8 and decided to buy it with a MMM. Ive been thinking of using the Team Orion molecular lipo which is 139mm long. Then i became aware of the problem with the motor shaft sticking into the battery department. I was wondering if i could do any mods to make this battery fit, or if there is any other 4S lipos i could use. I do not wish to use anything less than 4S. I live in Denmark so it has to be something available in Europe and not just the US.

Thanks
