I just replaced my ICE with a Hitec X4-Eighty. It has 4 separate outputs that charge 1-6S and have balance capability. The charger only comes with 1 balance board of each type, so I bought a couple additional ones that match up to the batteries I have.
There's also a temp sensor port for each output (but the sensors must be purchased separately).
The one drawback is that each output only has 80watts of output capability, so if you're charging a 6S pack you're limited to around 3 amps, so it will take a little longer. All of my packs are 2S and 3S (soon to have a few 4S packs) so this was not an issue for me.
