DC DC Charger (with 240V input also??)

Hello All,

I have 2 100ah agm deep cycle batteries for the back of my 120 V6 Prado. My 240 Charger just stopped working (only flickers from standby to charge then back again) I am looking for a way to charge these both inside and outside the car in the most economical way.

I was thinking, if they exist, that a dcdc charger with optional 240 input will be the best option, but I am not sure if these even exist, or if they are cheap. Does anyone know of any of these?

The other option I could think of is getting a DCDC and a seperate 240V charger that can do at least 100ah.

Any thoughts on the best way to go for this? Or better brands models?


Thanks

Here is a dual charger but the DC charge rate is only 5A

This one is better, Redarc BMS1215, 15A on AC, 20A on DC

Thanks AMTS. That first one looks good, though to charge 2x 100 AH will take forever, and WOW that redarc is very expensive. Curious for anyone who has one asre they worth the $1000+ or is a $300 Ctek or projecta dual inuput (DC + solar) and a $200 AC charger just as good?

also, would it be worth just getting a dc-dc and a 12v power supply to power it whilst at home? the DCDC will not be in the car permanently (at least to begin with) as it will be in attached to my removable drawers

If you run heavy enough cable to the batteries in the camper, you could rely on the alternator to keep it charged up. Then add solar panels with voltage regulator and connect it straight to the batteries when stopped on a trip.
A 10A 240VAC smart charger such as a Projecta would then be adequate for at home charging and maintenance charging. (I have the 7A version)

4wdextreme on ebay is local to Adelaide. Have bought a few things from him (no affiliation).

I have a Ctek 250S, I use the second battery under the bonnet to power my caravan.

I currently use a Dell Server 12V power supply to charge the battery off 240v using the solar input of the Ctek.

Hope that helps.
