noob quesion about battery fitment

[Shaun_TLR]

hi. my TLR 22 roling chasis has arrived this morning, and I guess its just straightoutta the box setup (via ebay). Im wanting to run saddle packs to give me some more room to run mid motor, but theres a housing bar to fit a standard size lipo one end, and the other end (where the motor would go if mid mounted) its not tall enough to get the saddle pack underneath.

could someone help a noob please? Ive posted a pic of the issue !! lol
