Ice is capable of only 1C charging, if your lipos are 2C capable and you want to take advantage of shorter charge times, maybe time to consider buying a more powerful, balancing charger.

There's nothing wrong with what you have though and there's more than one external balancer that can operate in charge thru and standalone modes and complete your setup. The Astro Blinky and the Hyperion LBA10 would be good choices.
