Hi all
I have just purchased a brand new SR5 Hilux.
My question is, i have installed a 2nd battery in the ute (not wired up yet) & i will be towing our Kimberley Kamper with it.

I have heard the Hilux alternators dont provide enough charge to 100% charge the 2nd battery. I see Ctek install a Dual DC to DC charger. thats fine.
But CTek say to install this as close to the 2nd battery as possible, no worries.

My problem is, I also want to charge the two deep cyles (200+amphr) batterys in the camper.
Can anyone tell me where i should install the DC-DC charger?
Should it be in the camper closest to those batteries, or still under the bonnet near the first dual battery?

Also, which charger exactly would suit best?

Any help greatly appreciated
Regards
Josh

Forget the charger with all those batteries it will take forever to charge them, better option is to fit a booster diode to the alternator.

What's the most important to you? If the fridge and essentials are running off the trailer, then that's where I'd be putting the DC-DC charger, right next to the two in the trailer. Ideally you'd want two, as I have done, one tending the vehicle spare and a second unit taking car of 2x140 A/H AGM's in the back of the ute. Have a look at the Redarc range of DC-DC chargers. I'm using the 12/20 and BMS. Latest version of the 12/20 is going to include a built in MPPT solar controller similar to the 12/40l (due out end of this month apparently).

Spoke to redarc

You need a 1220 in the car

& a 1240 in the camper.

Both connect to Main battery for sensing purposes.

good times

You're making headway. Only the opening of the wallet remains lol ;-)

Josh,

If you were to invest in a dc-dc charger, install it in the camper where your batteries are.

The input voltage to the dc-dc charger can be as low as 9 volts or so.
The charger should boost the voltage to that required to effectively charge the batteries.

I have a Ctek D250S Dual charger and that is where I've placed mine.

I agree with Sandman, I have a Ctek D250S, installed in my trailer, it charges the AGM battery in the trailer from either the Prado while we're running, or the solar panel when we're camping. Works beautifully.

Hi Josh

You simply require a ABD for the Hilux.

They are very cheap and increase the voltage by 0.5V approx. Available from 2 suppliers on eBay.

Inceasing voltage at the alternator will help with reducing charge time and increasing the amount of juice in the battery. Installing a DC to DC at the camper batteries will help too. but you will still need to do A LOT of driving to charge those suckers if they are drawn down
