I thought the dual bank controller might be a way around this. Any thoughts?

I'll admit that I am a little out of my expertise with the lithium batteries as they have onboard charge controllers, but if you are hooking them up in series, the charge controllers should be looking at total voltage.

That might be a better question for the battery manufacturer..
