I relocated my starter battery (original factory) to the trunk when I installed the Phantom. It died/was replaced on 07/2017 with an AGM. I doubled up on the power-sonics with a dual dump, and I think that made them last much longer by halving the workload.
I'm not sure what to replace them with. I know there was a newer battery replacement option for the power-sonics, but not sure what it was. I also wonder if anyone has worked out a capacitor/super cap setup that would work to buffer battery output. I would think it would maximize initial peak current plus help the dump pack last longer.
