Battery too big?!

Anyone running 5s 6000mah Enerland packs in their buggies? I am just finishing tekno conversion and have had to cut a huge slot in body shell to allow for battery.
Bit of a pain as it kinda spoils the shell but have no choice. I gues varying conversions have battery nearer to centre of chassis.
That's the worst thing about buggies, low sides to bodyshells!!!!
