    BCDC Redarc

    Hi All,
    Wondering which dual battery system to install. The traxide or the new BCDC 120 redarc which sounds good.
    Any thoughts or suggestions ?

    I think those that have the traxide are extremely happy with their purchase.
    I have used bulk chargers over the last 20 years (not sure how the traxide works), and have family in the battery industry. For the past four years I have used the redarc 20amp dc to dc charger. This is the best charging system I have used to date, and works sensationally well on my D4. Battery is always in tip top condition, something I have been let down in the past many times with bulk chargers.
    As I said, I don't know how traxide works and there are plenty of forum members that have them and all are happy, but the dc to dc charger is the one for me. I also use a dc to dc charger in my camper trailer, with batteries now 5 years old and still going strong, and they get hammered.

    I have had the redarc fitted in my D4 3.0 for nearly 3 years now and all is good. My view is that the D4 electronics and charging management system are to complicated and advanced to simply add a battery isolator system to it. The dc to dc charging approach looks just like another current draw to the car and the systems can sense that and manage it in the normal way.

    There are long and heated previous discussions on this question and these contain a lot of information. Main point is to not to connect the negative terminal of the dc to dc charger to the battery. Connect it to the earth points on the body near the battery. This way the electronics can sense the current being drawn by the charger and compensate.

    Good luck with your install.

    What

    Edit* Does the D4 have a shunt or something installed on the negative battery cable used for charge control? I assumed the D3/4 alternators were simply voltage sensing ones like most other cars??

    I believe they do, I found one on a 2007 RAV4 too. It's a modern strategy for reducing fuel usage by controlling when the alternator is needed.
