BUILDING a CUSTOM, one of a kind DUAL BATTERY set up! TB48 Nissan Patrol GU build 

Doesn’t the Victron dc to dc have a smart engine on detection sequence? I thought it measured the voltage every minute or so to detect if the engine was on thus shutting itself down if it notices engine is now off and starter battery not charging? Might be confused but I thought that was the whole point of going for a smart dc to dc charger.

@@duncanbrown7160 Yes, from Victron info "the default setting (13.3V) is based on generic smart alternator setup. Most smart alternators will generate 13.5V when the engine is running, and regular alternators will normally generate >14V. In an application with a regular alternator the restart level can therefore be set to a higher value, e.g. 14V." "Shutdown level: The default setting is 13.1V. this creates a hysteresis between the restart level and prevents excess discharge of the starter battery." Notice in my comment "the resting voltage of the Lithium will be at or above 13.6V " this is already above the default setting of 13.3V to start/restart and keep the charger on. So even during startup as lithium batteries maintain a steady voltage and strong current there will be no major dip or ramping of voltage required to shutoff the charger. Tyler may have to check what his resting voltage on his starter battery is and he may be able to adjust the Victron charger trigger voltage, but as my own Lithium battery tends to hold a resting voltage of 14.3 or slightly above. this may be too high for the Victrons settings

Thanks mate!

Yep that's what I was thinking, can run it in both 👌

Thanks 👍

Thanks!

For sure mate!

Cheers mate!

The victron has an ignition switch feature which you can hook up to only charge when the ignition is on. It comes with a bridging wire as standard but you just need to run a small cable to the ignition switch.

Thanks 😁😂

For sure mate!

Ditto on knowing more about the battery. I'm interested in fitting a lithium starter battery due to the weight saving, but keen to know how it performs or will last under the bonnet.

Cheers mate, not 100% sure to be honest! Worked great the last 4 months since its been in though

Glad you like them!

Cheers mate! I did end up seeing that but for some reason I thought it got in the way of the back seat but I guess I was wrong

Yeah they mostly get covered but I generally only use it with the inverter and lights etc when I'm at camp

Hasn't been an issue, and when I use most of the system like inverter and lights etc im pulled up at camp with the rear door open

Cheers mate! Yeah pretty set up now!

Yeah realised that haha but when im using it most for running camp lights and inverter etc it will be at camp when door is open anyways

Cheers! From here platypusoffroad.com.au

Cheers mate! Yeah something like that could have worked

Don’t you always run your winch of your starting battery ?

Cheers mate! Yeah its been great so far, used the winch quite a few times. I cant remember the figures but the lithium has much more ability to handle power then the standard battery I had

@@TylerThompson90 cheers 👍

@@michealedwards7849 I do Michael. I was wondering if a lithium starting/cranking battery can handle the amp draw under heavy winching.

@@wadefuller7283 you can buy lithium crank/winch batteries (expensive end of the range) not sure what’s the difference to a “normal” lithium battery. Some have a reserve, so you can just run 1 battery. If you manage to run it flat, open the bonnet push a button on the battery and there’s enough power to start -> that’s their marketing spell, I haven’t had one of them yet.

Thanks!

No, that at rule doesn't apply when the 240v gpo is supplied solely by a portable inverter. Different story if you have it setup to take 240v plug-in mains connection though.

Checkmate.

They are Drifta Stockton ones mate, can get them on their website

Yeah they can definitely make them mate if you chat to Hastings auto electrical

Yeah I take it out for daily driving mate

Yep they can make them if you contact them, they would make on demand though, they wouldn't have them sitting there ready to buy

@@TylerThompson90 thanks mate for getting back to me keep up the great work love watching your videos

Yeah okay, we couldn't find a good spot and can't put a lithium (non starter one) under the bonnet anyways nor the inverter

@@TylerThompson90 there are kits that you put a battery tray infront of the main battery, and you need to relocate the windscreen washer bottle to the firewall, can only fit a 90ah battery like in your vid though

Yeah it cant go anywhere though when its tucked in behind the seat as the seat is on an angle backwards so the battery cant actually go up. The whole seat would have to get torn out before the battery box could go anywhere

As was stated in the video. 👂

@@TylerThompson90 but it will unless its tied down, you have no idea of the forces.

@@qksmith Yes exactly, it can slide to the drivers side and out. One accident i went to (not far from where Tyler lives) a steel cantilever toolbox full of tools in the boot hit the boot lit hard enough to sheer the boot latch off. The whole thing was ejected from the boot and tools were scattered about 40 meters from the impact. I'd be bolting the box down if i was Tyler.

i would rather strap it down that put it though the back of a family members head.

lithium starter 1400cca would be good for winching too

Yeah I did think that haha but most of its use is when I am at camp (running lights and charging camera gear through inverter) which is when it will need more air and back door is open. When im driving its only running the fridge and doesn't create much heat

@@TylerThompson90 no probs then, looks good though.
