In my experience, third party batteries and chargers have always turned out "not to be worth it" in the end. As much as i think Canon (like nikon and others) are really gouging us on battery prices ...
With third party batteries i've aleays had issues. Not one of them had better than 80% of the original battery capacity, once they had bern in real use for more than a month. Not one third party battery was still usable after 4 years, wheras all of my canon batteries (various types) were - maybe down to "only 1 red dot"-health status, but still good to go.
I've had all sorts of compatibility issues - both mechanicallx (battery nearly stuck in camera slot) and electrically (third party battery overheating in original canon charger on 1st charge, etc.)
Rspecially when a new type of canon battery comes out like lp-e6N, i' definitely be extra careful with third party batteries. The chinese manufacturers may not have really completed their reverse engineering exercise yet.
But ... YMMV.
