Recommended Battery Isolator for Ram ProMaster with 220 Amp Alternator
Question:
Question about the Redarc Smart Start Battery Isolator - 12 Volt - 200 Amp Item # 331-SBI212 I have a 2020 Ram Promaster being built as a camper. Will this item work with a 220 amp alternator and a lithium ion 12v battery in addition to the lead acid starter battery. Thanks

Helpful Expert Reply:
In regards to battery isolators, they should be rated at or close to the changing amperage rating of your alternator. They don't really need to exceed this as it's very unlikely your alternator will ever reach its max charging amperage therefore, I recommend the Redarc Smart Start Battery Isolator part # 331-SBI212 which is rated at 200 amps and the highest we offer. That said, these don't work with lithium batteries and the highest rated battery isolator we do offer for this is the Redarc Smart Start Load Disconnect part # 331-SBI12-LLD which is rated at 100 amps.
In other words, we don't have the prefect solution for your setup but we do have one that will work if you consider a lower amp alternator or non-lithium batteries.
