Correct.

Re: Lifepo4 Batteries
Thanks! Couple more questions if you don't mind: 
The way my system seems to have been designed from the factory is that there is also a feed from the port isolator that goes to the house battery to keep it charged from the alternators while underway. It seems to me this wire has to come off otherwise the alternators still have a direct charge path to the lithium bank. Did you run across this same setup?
Also, since my alternator sensing leads currently run to the house bank (currently flooded lead acid), it seems I should remove it from the house bank and instead run it to the applicable starter battery. Does that sound correct?
Sorry for all the questions but I want to make sure I get this right from the start and don't damage anything or have to do rework!

Re: Lifepo4 Batteries
Yes on both accounts. No communication between LifePo4 bank and Lead Acid bank. My isolators were set up the charge between 3 banks (start, start, house) , I simply disconnected the lead going to the house bank. This way I had a fall back plan if I overlooked something and needed to go back to lead acid house bank. Nothing to report that would have me do so.

Re: Lifepo4 Batteries
My thoughts exactly. And I'm glad to hear there were no unforseen consequences. Thanks again!!
