This item is brand new purchased back in November 2024. It is a 12-12-18 Isolated model. I purchased by mistake, i should have bought a 24-12-20, and have only just realized pointed out by our electrician, but unfortunately the company cannot accept this to change for the one that we require due to the time laps, so selling on to purchase the other one. I still have the receipt, so it will still have its 5 year warranty. Thank you for looking.
Used in 2007 transit for second battery, far better than normal second battery connectivity. Once engine stopped there is no connection between the two.
