"I personally use Hyperion chargers, a decision based upon their earlier models. Rugged and strong case, easy menu systems with a wide range of settings, logical displays and well supported here in New Zealand under warranty. This one is my favourite due to its pre-installed AC power converter. Bigger and more powerful units are now available, however I don't charge my batteries at 10amps! And I doubt you really need to either."
