The 150 series Dual Battery Guide

[KeenOnFishing]

Hi guys,
I have just been told by someone that if I want to use my dual sensing isolator to charge both batteries through a charger plugged in to an Anderson plug at rear. (Charging Aux first then start battery) Then I need to add a diode between the alternator and start battery to stop the charge getting back to the alternator and ruining it. Can someone confirm if this is correct? If so do you know where there is any info on this?
Cheers

dBC would be correct with about 500mA. I rang redarc with the same question and asked the question about the 3A rated switches. He said it would be fine, didn't give me a hard number but stated there was "stuff all" current going through it and my 3A switch would be more than enough.
Here is a photo of what I have installed in mine. No issues!

Thanks Guys,
I think I have the same switch Jimmy.

Hi guys,
Can anyone tell me what size cable I must run from the blue override wire on red arc to the switch in the cab. I am thinking some really light cable with a 3A fuse as this is what the switch manufacturer states is appropriate. Just want to make sure this won't catch fire when overriding or similar. Ty

That blue wire override just energises the coil of the solenoid. I've measured it on my SBI12 to be about 500mA.

Just received notice from the supplier that the booster diode I have does not work in the 2016 Prado.

That is correct, at this stage there is no voltage boosting option for the 2.8L unfortunately.

A few weeks ago I purchased a booster diode as I would be installing a dual battery system in my 0416 build 2.8l Toyota Prado.

The install was mostly completed yesterday but ended with a slight glitch.

The info sheet with the diode advises to install in the fuse box by removing the small ALT fuse 7.5 or 10 amp. My Prado does not have a fuse marked ALT, although there is a 7.5 amp fuse marked SMART. I'm thinking that this may mean SMART Alternator

Would this be the one to replace with the new booster diode?

Hi max

It's in the battery box.

Hi Little OZ,
Where do you plan to put the 20A Redarc BCDC charger? Will you mount it in the car or leave it unmounted so you can take it with the battery box to e.g. connect it to solar panels?

thanks,

Max.

Thanks Micheal

Just had a look and they also have a deep cycle marine/cranking option. This might be the way to go.

I'm looking at using a battery box with a 20A Redarc BCDC charger with an Andersen plug running from the engine to the back of the car. I rather use the portable option in case I sell the car in the future I also want to be able to take it out and use around the campsite. I just want to check the best battery to use. It will mainly be used for a 40L engel fridge and led lights. My original option was a 120AH deep cycle however I have also been looking at the Optima yellow top but I think it only has 66AH. It will mainly be used for short trips on weekends however it will also get the odd longer trip of 2-3 weeks. Can the yellow top also be used as a marine battery, I may also use it as a second battery on the boat.

Thanks

Hi Little Oz.

The Optima would be fine for deepcycle and marine use, and using around (the recommended) 50% of a 120ah is not that different to using most of the 66ah in an Optima.

Recharging via the BCDC will obviously be limited to 20a/hr so you just need to allow for this when you're not driving for a few days...

Leigh, can you pm a link to your booster diode please. Or tell me which one it is. There's lots on eBay but not sure which one is yours.
Cheers
