Thread: DT90-L322 Range Rover Dual Battery Kit Installation

Thanks so much Tim. If it helps, I can bring the Range Rover to you if you need to pattern it or something for future work? Anyway, let me know if you want the car or when the system is ready and we can close the deal.
Best regards
Grant

Hi Grant, and thanks for the offer.

I am on the Gold Coast. But if you are near, I can do you a deal if you can supply a Guinea Pig for the new wiring set up.

The main DT90-L322 DBS is exactly the same setup, it is just the set up to the rare bumper that I have to finalise.

Regards, Tim.

Tim, I am in Sydney but happy to bring the car up for the guinea pig work. Car is in the panel shop now after my recent parking,lot issues but will be back next week.
I'll stay in touch and if you still need the truck in a week or so, count me in. I'll bring the bride and take advantage of the hotels and food whilst you work your magic if that is ok by you?

Hi Grant, let me know when you are coming through and I'll be ready for you.

You will need to allow for about 2 to 3 hours max, for the new kit installation.

The existing kit takes less than a hour but I don't have my L322 available, to work out where the cable to the rear bumper has to go, so I will use yours, but I think it should be pretty straightforward.

Thanks Tim.

Thanks Tim for the Kit.
I put it in this week and it's a fairly straight forward install due to a few little tricky things already being worked out by Tim.
Like the length of the brace, the angle cut on the end of the brace etc.
The battery looks like it belongs in that spot too.
My only question is what are the flashes on the led?
Eg what's 3 red flashes then one green?
What's constant red?
Also is there any way to start your car from the second if required or should I get a long set of jumper leads?

Hi, nice kit.

I do have a question, i always read that 2nd battery should be the same capacity (or less 10% maximum) as the 1st.

When i see a Optima D34 55Ah with a main 110Ah, i'm asking by which miraclethat does it work good?

Second batteries can be any size, and type, don't believe everything you read on the Internet. . Think of it this way - the second battery will be discharged at a different rate to the first no matter what size it is when you're out camping right? When this happens and you start the vehicle, each battery will still pull different amounts of current from the alternator to accept a charge, regardless of if they are the same size or not. Once both batteries are full or nearly full, the charge current to each may stabilise at a few hundred mA but that's the only time you'll see them draw similar or equal currents, so how does size come into it at all?

That sort of spiel usually comes from a salesman or website trying to sell you something you don't need, don't fall for it.

As an example, when towing my van with the work car, the alternator is charging 4 batteries - 2 in the van (100Ah deep cycles), one in the back of the ute (N70) and the cranking battery (something smaller that you would think being a 4WD)

No issues at all - and I've done this sort of thig over many different vehciles over the years and I get very good battery life (5 to 7 years) on most batteries I've had.
