cougar sv batts

[clemo]

Hi all,

just bought myself a cougar sv1 with an +8mm chassis and its set up for stick lipos,
could any one let me know what size lipos fit in the space or what people are using,
i have saddle pack lipos at the moment which fit my 4wd so i dont know weather its going to be cheaper or better to buy the posts and top tray and go with saddle packs,
thanks in advance for any help, rob.
