Try reading all the replies again!

I couldn't find the bit where the Fullriver graph was discredited. What proof did this writer give in their post?

I am not sure why I have been singled out as the only one who is required to post proof for everything I post, but so be it.

I will start a new very brief thread for my last comment on this subject, and will include full proof of what I write. I just ask that anyone objecting to it also provide proof of why they object.

Hi Peter and to be honest, my suggestion to you to do some additional testing was really to show you, through your own testing, that you could save yourself a bucket load of money.

As already posted, when you add that new battery, you will make the use of the DC-DC device a waste of time because you will now need to do so much more driving to allow your device time to charge your batteries.

But just to give you a comparison of what you could have achieved for a lot less money.

If instead of spending around $500 for your DC-DC converter and now an additional $200 on a 3rd auxiliary battery and this doesn’t include all the additional cabling, to set up a system that will take quite a few hours of driving to charge your 3 batteries, if all your batteries are low.

OR

If you had spent say around $350 on an SC80-LR kit, which includes all the cabling, not only would you have a set up that works perfectly first time in a D4 ( you posted you had to work out how to wire your DC-DC device to eventually get it to work ), but because of the way the SC80-LR works, you would not need that 3rd battery that your current system requires, which means you would also save the loss of space and having to carry the additional weight needed to accommodate the 3rd battery.

Just a another suggestion that would actually make you some money. You could flog off your DC-DC converter on Ebay, buy and SC80-LR and by installing an SC80-LR, you would save even more money by not having to buy that 3rd battery.
