Is there a mod for minecraft that gives you extra inventory space?

I'm currently using tinkers construct and LOTR mod, so I kinda need the extra space. I've tried to get he backpack mod, but it's not updated and doesn't work for 1.7.2.

Ender Storage is upgraded and it adds backpacks.

Edit: Oops, forestry is not updated yet. Forestry is also a mod that is updated that adds a bunch of backpacks, which among other things automatically put things the pack is compatible with into its own inventory. By default these are just 15 slot packs, but they can be upgraded to 45 slots.
