Dual Batteries.

[numpty]

In my Stage 1 I have a large marine switch which I use to manually select between either Bat 1, Bat2, Both or off. Can anyone tell me if this method is possible with a TD5 or will it play havoc with the electronics. I ask as this is the cheapest and easiest way to charge 2 batteries in my humble opinion.
Looking forward to replies.

have a look at the Traxide sponsors site http://www.traxide.com.au/

I have their SC40 and it works a treat https://www.aulro.com/afvb/

Plus if you mention AULRO to Tim then he'll discount you 10%!!!

Hey Perry

I have the marine isolator as well, it was it the defender when I brought it. It,s simple, has no electronics and you can run what ever size cable. Although I call it the IDIOT switch as this idiot has forgotten to unisolate every now and than, once flattening the start battery, no problem as I selected both batteries and jump started myself.

I couldn't see a problem with it on a td5. I have never needed to isolate both batteries to date so if the electronic need constant power there should not be a problem.

If my next landy does not have an isolator than I would go for an electronic one. I would consider TRAXIDE, a few of the lads here have installed them and they seem to be doing the job.

I have the marine isolator in my EFI Rangie. The biggest risk to engine electronics is switching transients (voltage spikes) caused usually by the coil of a solenoid. Electronic battery systems have filters to eliminate the transients (at least the good ones). The marine switch does not have this problem because it is a manual switch. The biggest problem that I have found is remembering to isolate the starting battery before the fridge has run both flat. This is not a problem with the electronic systems because this is done automatically.

<span style="color:blue">ive got the SC40 installed and have been thinking of fitting a hand operated isolator
switch as well....if the main battery dies or goes flat because someone forgot
to turn lights off....a simple turn of the switch will join the two batteries together....
eliminating the need for jumper leads.....too easy me thinks.....</span>

Hi Zook, I’ve had so many requests for battery switches I now have some in stock.

I’ve just got to get my finger out and load pics and pricing onto my site, along with some simple info and a diagram for fitting them with either the SC40 or SC80.

Cheers.

<span style="color:blue">joining the two batteries together shouldnt affect the SC40 should it.....?

i would like to have another small battery fitted only for trips to remove
from the vehicle and run lighting away from the car......a small 17ah battery...
a bit bigger than a house alarm battery....

a second SC40 should be just perfect for this application should it not....?</span>

Hi again Zook, as much as I like parting people from there money, in your case, with such a small battery that is going to be removed, by the sounds of it, more times than it’s going to be connected.

What I suggest you do, is get a set of Anderson plugs and some cable.

Fit a short length of cable to your existing auxiliary battery and do the same to your small battery.

Then when you are going on a trip, after starting your fenda, connect up your small battery. By doing it this way, because the motor is running, the vehicles voltage will be higher that any of the three batteries so there will be no problems with lower charged batteries trying to pull power from higher charged batteries.

Cheers.

thanks for deleting my multiple posts, i was away from the pc over the weekend and thought i would have a second attempt at posting a reply with my work supplied blackberry, it seems every time i click the back button it reposts the post. it's not to bad to read the site, about half the speed of dial up, no more attempts at posts from now on.

I use a marine switch to run the winch from. That way I can use both batteries for winching if I need to. I also have an electronice charge controller, as well as one of Drivesafe's SC40s set in Accessories mode.

There is a write up with some pictures here (http://forums.lr4x4.com/index.php'showtopic=1503&hl=)
