Don't know if there's an upper limit. At least you can use your gems to buy more slots than you'll ever need. For me I thought 40 was a good number of slots and I've never needed more than that.

But anyway, try to stack your charms as much as possible. A stack of any number of charms still just takes one slot. Don't merge charms unless you're either going to socket them or if merging will save you a slot. Since level 5 charms are the highest level that drops and since challenges gives you level 5 charms, you'll likely have mostly level 5 stacks.

Ignore the crappy charms. There no point to saving Soldier charms. Every other star shaped charm is better. Don't save Heart charms if you can get a couple of Bandit charms. Don't use Power charms if you have Agility charms of the same level. Don't save Arcana or Fortitude if you have a few good Essence charms. And so on.

Also, if you have spare weapons to complete challenges you can use them to temporarily socket charms.
