Wiring Up Two Nsbs Correctly

[Scarab229]

I have a Optima bluetop upfront and two Nsb Red 110s running at the back to a Taramps Hd8000 on a Single 50mm run of cable. I want to upgrade to two 70mm runs but do I connect the Nsbs off the Optima or directly off my Mechman 240Amp?

mechman recommends only having one charge wire attached to the charge stud on their alts.

So, run a large wire from alt to front battery, then do your two runs from front battery to rear battery
