Dual Batterys

Post by **Andy** » Wed Nov 05, 2003 3:36 pm

G-day all , been of line for about a week cos I got a little curious and clicked on a titty web site ( Spam mail ) and downloaded what I thought was a bit of porn ( as any bloke would :lol:

) and ended up loading a programme that f*#ked everything up big time , all fixed now with Spam filters etc ....... Anyway , finally finished the dual battery set up in the Big - Rig . It's got a auto solenoid thingy that switches batteries when needed and a manual switch to do the same , simple set up really . I'll post some pic's when I get my didgi back ..........

Andy,

I look forward to the dual batt. piccies and maybe a wiring diagram. As for the enticing web site...no comment :roll:

I don't know if you run Ad-aware 6.0 but you might want to. It's free. Some sites upload a data miner to your registry as well as cookies. Information gathering site tracking sort of stuff. This will eliminate them...till you get more. I usually run it once a week or so.

Spybot is also worth checking out. I was running Adaware but changed to Spybot and have found it better- it detected more spyware too. It also blocks dialler programs from disconnecting you and then dialling international numbers..... Plus it blocks dangerous cookies live while you're browsing- you have to pay to get the same functionality on Adaware.

Andy,

Care to let us know how much you paid for the auto solenoid switchy thingy? I've been looking around for such things myself, and find they seem to start at $270ish. Maybe that's the going rate, but it seems mighty high for a soleniod, some diodes and a voltage sensing circuit to me. I've already got the batteries, clamps and trays for nothing, so I'd love to do the circuit on the cheap, and I'm not afraid of a bit of soldering.

And the ad, spam, nonsense. Not all cookies have malicious intent (most don't). Don't touch executables from unknown sources! Ever! Or just get a Mac and be done with it :twisted:

Ahhhhh, have I got just the thing for you! :twisted:

Better start heating up your soldering iron.

Here's my dual battery set up that I posted a while ago.

Woohoo! You rock

I'm just about sold. I think I'll duck into DS tomorrow to have a look. How have you found it in operation? I found the description a little on the light side - those dot selling points don't lend themselves to a decent electrical description methinks.

When the engine is running, are both batteries under charge? The commercial kits I've seen charge the main first, and only start charging the aux once the main is full. It does appear to protect one battery if the other decides to loose a cell (which would drain both batteries without the isolator), which is what I'm after. Sounds great in any case.

OK. Some points I remember about the kit (both good and bad):

1. It limits the charge current to a flat aux batt (<10.5V) to prevent battery damage.

2. It's limited to a max charge current of around 30 amps, and the lead to aux battery must have some resistance in it for feedback to the control circuit.

(not really a problem in a Feroza as the alternator can only supply 55amps anyway)

3. It will not start charging the aux until the main is above 13.5V

4. The internal MOSFETs have diodes that will allow current to flow back into the main battery with the ignition off. Very bad if you leave your headlights on- both batteries will go flat!

4.5. The MOSFETs conducting as above will help boost your main battery when starting.

Also can stop the conduction with the addition of a heavy duty relay (in the aux line) wired up to the ignition if you wanted to.

5. You can modify it to suit your own needs (eg I got rid of the external terminals and ran the wires directly to the circuit board)

6. You will need to bugdet for heavy duty fuse holders for the line from the main battery and line to the aux, they're not included in the kit. Plus some heavy duty wire etc:x

Another point- buy the kit from Dick Smith, rather than Jaycar, as the DS kit comes with a deeper aluminium case which is a lot easier to squeeze everything into.

Anymore questions let me know.

The new soft ware I'm using is Spybot and Mail Washer , the Mail washer opens your mail at the server and not in your mail box and give you an option to black list and bounce back the unwanted mail , I think it's great cos now I can get the Spam gurus back at there own game .......

As for the battery set up it's got a heap of heavy duty wires or battery leads , a few small blue and black wires , a $34.00 solenoid ( trade price ) and a $21.00 switch . As you can properly work out I didn't fit the wiring , an auto sparkie mate did it for me , I just pretended to I know what he was doing and talking about , hope that helps you Kent :lol:

We want pics!!!!

What tray did you use for the aux battery Andy?

David,

Thanks for the spybot tip.

Andy,

We want pictures

The batt tray I made my self , be bugged If I was going to pay $100 plus for a bit of metal

Batt Pic's :lol:

Those aircon lines are a real pain in the butt, aren't they Andy!

Stopped me from fitting the battery I wanted originally as the tray couldn't be mounted low enough. I see you've managed to squeeze your's in front of them.

Post by **Andy** » Sun Nov 09, 2003 8:58 am

Yer I had to mount the tray just in front of the air-con lines so the tray could sit lower enough , but doing that I now have a mounting point for air compressor ( ARB maybe ?? ) and retire the cheapy one I have . The only bad thing about the second batt is I have to take out the batt out to remove the air filter . I'm looking into getting a Cruiser filter box or simular so the filter is taken out from the top :lol:

I've got a Bushranger Maxair, it's a bl**dy impressive bit of gear. 75l/m maximum and comes with a hard mounting kit, plus a canvas carry bag. Takes no time at all to add 5psi to my 235/70r15 tyres- I haven't had to air them down yet for sand.

Picked mine up for $292 from Rays Outdoors.
