  • Query re: aux battery and Anderson plug power to rear

    Hi all,

    I have a dual battery system in our prado, but find that when not on big trips there isn't enough charge getting into the second battery. I occasionally clip the charger on, but with a new battery soon to be installed I am thinking of connecting a short section of heavy cable to an Anderson plug on the front grill so I can easily connect/disconnect the charger. Does anyone have any thought / advice on that??

    I also want to install an Anderson plug on the back of the car so I can feed power to the vans fridge. Would I be able to loop off the rear plugs (which are wired up with 6mm)? Or would I need to run a new feed from the battery?? Again any comments would be appreciated.

    Cheers,

    Scott

    There is a lot of data on this forum as we all share the same issues. Some guys also put a charger in the loop every month (I think an Anderson plug is overkill just for a low amp charger access). You will find some more info here but can you list more on your personal set-up? (wiring used, isolator used, battery type, alternator booster diode, etc.)

    The cures seem to be:

    1. Alternator booster diode (gains ~ 0.5v @ $35.00)
    2. DC-DC charger (high speed charging but efficiency effected by heat under bonnet @ ~$300.00)
    3. Replace alternator wire to heavy gauge on D4D installs (PITA to install gains ~ 0.5v)
    4. External top ups (high or low amp chargers, solar power etc.)

    Your second question would depend on the length of cable and the amount of current the fridges in your van draw. I'm thinking it's over the edge and you would be loosing some efficiency if you are running 6mm with 2-3 fridges?

      I have a 7A Projecta multi-stage charger to charge my portable aux battery. I used 15A cable and Anderson Powerpoles with 30A crimps bought from an ebay seller in the US. You can get dustcaps for them. http://www.powerwerx.com/powerpole-accessories/

        I will second the powerpoles. National Luna fridges use these as the connector (at least mine does) and since then I have used them on all sorts of things.

        As peril has said you are best off searching within this section and see what you want to do and what has been done by others.

        I am finding with the 150 where I have fitted the auxiliary battery (120AH AGM) and DC DC charger (Redarc BCDC1225) in the rear cargo area that my auxiliary battery is being kept much better than when I had an isolator system and AGM under the bonnet on the 120. I used to have to top up the auxiliary with the smart charger every few months, more so around school holidays when the car doesn't get used every day. didn't use the booster diode though. I think that AGMs are far more fussy with how they are charged than conventional heavy duty or deep cycle wet cell batteries. Plenty of people have good results with these batteries and the booster diode. The downside with my system is the space it consumes in the back, not such a big deal I guess since the fridge lives in there pretty much permanently, have a look through my build to see. I ahve no experience on the DC DC chargers under the bonnet but Redarc do mention about temperature derating for these. At the end of the day your alternator can supply only so much energy and that is what you have to work with.

        6mm wire is too small to run a typical fridge or charger in the van if you are talking about 6mm2 or 6mm automotive wire. I use 6 B&S and that works out to 13mm2. Some people go bigger again. Voltage drop is a parasite you need to keep under control. It wastes your power for no good reason.

          Same with mine

          and since then I have used them on all sorts of things.
          Same here as well. Just bought 20 pairs off ebay and need to find a good crimper for them.

            I have used these for 30 years, available through clipsal or Jaycar, simple and reliable with bugga all voltage loss, rated up to 15A @ 32v.



            As for AGMs, the advantage that sold me was lower plate voltages. This in layman's terms means the battery requires less volts to be fully charged. In our situation where we have a lower voltage charger this means we get a more fully charged battery end state. Add a booster diode and you should be able to achieve 90% charge in an AGM, where in an equivalent standard wet cell battery you may only ever reach 85%.

            Rough guide example of course.

            -------------------------------------------

            Just found some specs. in the Redarc brochures that indicate the required volts for each of the battery type to reach full charged state. I'm not sure how accurate this data is but it makes an example for the using the AGM types to get the most out of your alternator.

            Required Max Charge Voltage:
            AGM 14.5v
            Standard Lead Acid 14.9v
            Calcium Content 15.3v

            So if you can generate 14.5v constantly then your AGM should reach a fully charged state according to the below brochure.

              Powerpoles are really neat and easy to fit. They are compact and 'click' in which means they don't vibrate loose. The basic design is the same as the larger plugs so vibration doesn't result in arcing which can happen with other plugs, typically cigarette lighter style.



              This is the back of the battery / charger box with the 3 gang outlet. Red wire is the trigger to tell the charger the engine is running, well ignition on. The middle plug is connected to the Volt meter and the LH is the fridge supply. All run in conduit so neater than these pics suggest.



              Here is the socket up close. You can get different arrangements. I probably should have gone for an 8 gang or bigger but didn't think I needed it at the time. Never hurts to have aux battery outlets. Since this picture was taken I have added a USB and normal 12V socket on top of the box for charging phones etc when the car is parked.



              And the fridge socket, I have fitted a power meter in line that sits at the back of the fridge and the cable is run in corrugated conduit too.

                Thanks for all your replies. I have talked to an auto-electrician and will need to test out a few options. We are going to fit a new aux battery and will look at optins for easy charging when not being used enough. I will try to post details of the outcome.
