Thanks mate. I'm at Little Desert this long weekend, there's 4WDing to be done!

I have a Victron 18amp DCDC. When parked up I often just put an 8 amp ctek charger on the main. (your scenario 1) The main goes up and the DCDC sucks 18amps out until the voltage of the main drops. DCDC cuts out and the ctek continues and the main voltage goes back up until the DCDC kicks back in. This cycling goes on for a while with ever increasing cycles but eventually the DCDC goes to float/monitor mode on LifePo4, the ctek then finishes the main charging and goes into float. Once everything is up to voltage, if the fridge is on during the night (solar keeps up during the day) and takes a gulp from the LifePo4 the DCDC goes back into adsorption (up to 5 amps) and it takes a sip from the main but that is quickly recovered from the ctek. Often the best solution is the most simple, so for me adding another device to the system is undesirable. I suppose the down side of my method is the main battery and DCDC is cycling a bit and shortening its life span.

@LockyourHubs4WDing

The whole cycling thing wouldn't be ideal, especially for your starter battery. Another solution of course is to use the remote feature of Victron to only turn it on when the ignition is on (when the engine is probably running)

Excellent explanation, thanks so much. I plan to use this as you've indicated, and then another easyas relay between my alternator and 1.5kw inverter wired to my truck (with 270 amp alternator) that is used for tools and other alternating current appliances. The truck doesnt have a large lithium battery to run the inverter, so inverter should only run from alternator.

Who invented this JAS Oceana (LV brand) or GSL Electronics - I prefer to buy from the real originator - unless it is widely licensed and quality controlled (then they still get royalties to create great new stuff).. It seems a fantastic way to get an "Ignition source" anywhere, it may just stand in instead of running the headlights to keep smart alternators from dropping the BCDC / DC_DC offline. (I have a dual input DCDC meaning that if parked up for a while, solar keeps all the accessories humming along and backfeeds the start-battery with a trickle. Another wiring detail I haven't done yet, but overcomes the the hassle of getting (fused) power (or ignition signal) from the Main Battery / or from switches in the cabin can be overcome by placing an additional "7 core trailer cable" (or other single jacket flexible multicore) from the engine bay/cab to the canopy, double insulated, all in one shot - need more, add 2 - ( relay and fuse all loads at common, easy to access points).

For my van house battery, my auto elec ran the large cables through a 100A relay under the bonnet and then to rear of the vehicle. This relied on the ignition to open the circuit in the relay, rather than running the Enerdrive DCDC ignition wire up to the vehicle engine bay. For my under bonnet dual battery I use Projecta DCDC 25 with ignition wire wired in. Although I was suspicious of my cranking battery being drained to the deep cycle dual battery when I charged it (as per example in this video) but I was relying on the DCDC to protect it with the ignition wire. I started removing the fuse between the two in case it was draining and was considering a high amp switch instead. Not ideal solution though. I really do enjoy learning about DC wiring like this, even if I don't have an immediate use for it

Nice one Simon😎. I have a Redarc BCDC charging my lithium aux battery in my 200 Series just like you have in your diagram. I will be replacing my lead start battery with a lithium cranking battery. I understand an issue this creates is that the lithium start battery voltage does not fall below the Redarc BCDC threshold voltage until it’s been pretty much sucked dry by the aux battery. I was just going to put a simple relay on the BCDC that activates when the ignition is on, and cuts the power completely to the BCDC when the ignition is off (thereby separating the two batteries from one and other). Is this relay a better solution and why would that be the case? Cheers mate👍😎

I see the Victron has a jump wire, and a switch can be fitted in between the loop (AS relay) and will work fine. I have the Redarc BCDC charger, and the blue wire connected to the Ign will turn on the charger at a lower voltage 12 volt on 11.9 volt off. Q. will the Start battery still change the setting of the BCDC charger at 13.2 volts when charging the battery with a 240 Volt 1-10 amp even when the engine is not running?

The Redarc is a pain..... When it sees an increased voltage (regardless of using the blue ignition wire or not) it'll turn on the DCDC with the increased voltage on the supply red wire and you can't change the settings..... The easiest thing to do would be to put a heavy relay in the supply line (red wire) to the DCDC charger controlled by the EasyAS. That way you can bypass the "smarts" in the DCDC and actually control the thing how you want too.

I don't have any experience with the Atem specifically, though they pretty much all work the same. The only thing to watch out for is some DCDC chargers (And I'm thinking Redarc here, though there may be others) will turn on when the input reaches a predefined voltage, that isn't user programmable. The way around that is to isolate the DCDC chargers input using a heavy duty relay that is operated by the EasyAs. (As the EasyAS is only rated to 8A)

Firstly disconnect the EasyAs from the DCDC, then with a wire directly from the battery positive, make sure the DCDC only starts charging when that wire from the battery positive is connected to the ACC terminal on the DCDC. If that passes muster, then get a globe (12v 10w should do the trick) and run it between the pin 2 of the EasyAs (the output ) and negative. Then make sure it's working as per the video.

Sorry mate but this is incorrect! The ignition wire on a dcdc is to tell the dcdc to continue charging regardless if the input voltage drops below its cutoff point (when a smart alternator drops it’s voltage.) As long as the dcdc has that 14.2v input it will turn on regardless of the ignition wire being energised! So if u connect the ac charger to the starter battery the dcdc will still turn on because the voltage will rise above the dcdc cut in voltage.This relay achieves absolutely nothing.
