The charger itself is only going to be able to handle so much power though, most likely limited by it's ability to shed heat. You might want to keep an eye on the temperature, and upgrade the fan if necessary.
Of course the fan driver circuit will also likely be limited in how much power it can supply, so you might end up having to use a 110/220V AC fan connected directly the mains input. That will work fine but you could end up with a rather noisy charger.
As for that battery, it's pretty large, I'm fairly confident the charger will melt before it harms the battery.
