Leave the isolator out of the system COMPLETELY!!! They are a waste of time and energy for a daily driver. Replace both batteries at the same time, use identical batteries when you do so, and wire them in parallel. Done and done...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
