Replacement Battery Isolation Manager for Precision Circuit BIM 160

Updated 04/29/2024 | Published 04/28/2024

Question:

I have an RV with a Precision Circuit BIM 160 battery isolation manager that apparently failed. I can no longer charge coach batteries by alternator. I have 14v in and 12v at the ign terminal, but it is only reading 12.3 v to the coach batteries. Long story short, which battery isolation manager that you carry is comparable to the one I have? I have all lead acid batteries at this time. 1 vehicle battery and 2 coach.

Hey Steve, so the most similar option that would be an upgrade to what you have now would be the Redarc BCDC charter part # 331-SBI12-BLD which will do a great job managing all of the batteries in your setup that need to be charged. This has an output amp rating of 50 amps.
