Its about time. I've been waiting for a 40A DCDC charger from your guys for a while now. Awesome.👍

Good to see commonly requested features being installed!

The voltages look ok for todays lithium. Some people will suggest 14.5v is a bit high (it’s ok though).

Some questions to clarify operation…
1) Does the Solar Priority mode automatically stop after a period of time or because of some event (such as no solar available, vehicle starting or stopping, anything else)?
2) Does Solar Priority mode operate in conjunction with Alternator input, or does only one input operate at a time? (the manual doesn’t make this clear). e.g If solar can charge at 5A, does it then take 35A from the alternator, or does it neglect the alternator completely? And vice versa? I expect they operate exclusively, meaning only one at a time.
3) Is it IP rated to any standard? No mention of if it’s ok for engine bay mounting, Ute tub (possible rain getting to it) or other places like that.

32v solar is ok, but if you can revise the design to accept 40v this will make it much more attractive to people using bigger "house" style PV that can operate at 36v or a little more.

And the mention of the load on the engine is misinformed. These will drain about 600w maximum, and engines will produce between 50, 000 – 200, 000w. So the load on the engine is negligible and one could realistically say it cost them extra fuel. Other driving factors play a much bigger part in engine load and fuel consumption. Good marketing, but incorrect 😉

I wish I had a need for this because it'd be good to purchase for a full test, but without that need it's not quite in scope.

Hey mate where does the temperature sensor get connected too?
And I’m running 2 of your 170amp slim agms is it ok to run this charger as mine just turned up to replace my 25 amp I wrecked when my solar panel destroyed itself in the wind and shorted out I think 🤔

Hey Craig how do you reccomend installing the 40A DC-DC on top of the Kickass Jaxbox x1 Powerstation?

[abdushaheen]

Does it need an adpter to charge lithium battery, or is it the same redarc smart ? And how many times does it need to battery 100?

[fatmanoverlanding]

Will you eventually offer one that is already pre-wired to your Control Hub?

I just purchased one of these chargers and I cant get it to change modes, its stuck on gel. Have you guys updated your support portal to include this 40 amp charger.

[TheReganOfOz]

With regards to the ultra slim battery. They dont have any battery terminals so what does the temperature sensor from the dcdc charger connect too? Is it required?

[trainstrains]

If I buy one do I get the R2D2 and the Tardis behind you as well?

[Speedy]

Do you have any problems with RF interference with your car radio with Kickass dcdc chargers like some cheaper charger's?

When will this be available on the USA site? :)
