What are all the maximum upgrades for TH 7 defense ?

I currently am maxing out my base, I have:
- lvl 8/maxed Archer towers and cannons
- maxed/lvl 5 air defense
- lvl 4 mortars
- lvl 3 wizard towers
- lvl 1 telsas
- lvl 6 walls

Thanks guys (:

Level 5 mortar, Level 4 wiz tower, Lvl 3 Tesla, Lvl 7 walls, are max for town hall 7. Cheers

Just saying, google it and I'm pretty sure the Wiki page will let you know said info.
