Battery Combiners vs. Battery Isolators?


If I install the ProIsocharge battery isolator do I discard the ACR or is it worth keeping in the circuit? With respect to the ProIsocharge, there is a 180-1-2 and a 250-1-2. Which would you recommend?


No need for an ACR between your house and engine battery if you have the ProIsocharge device connected to your alternator output and have a charger with multiple outputs. I would recommend going with 250-1-2, that way you will have lots of capacity past your alternator output.
