My recent Hyperion Duo3, with version 4.5 firmware, has the current adjustment limit set to 2C by default. The charge value still starts at 1C after you set the capacity.

It can go higher by adjusting the limit in the user setup, I think to 5C. Assuming enough power is available for the size of pack of course. (3C for a 5000mAh 2s, just over 2C for a 4s, for this charger, per port)

Thus no need to fake the capacity to get a higher charge rate.
