Seems like a good battery deal, i had 1 battery from this shop from 2 years ago, and it's still holding up stong.
Excludes Northern Territory, WA Regional, WA Remote.
My car currently has a lead acid starting and deep cycle in the engine bay with a simple voltage regulated solenoid to charge the deep cycle. It does have a smart alternator, so I find I have to replace the deep cycle every 3-5 years even though I regularly charge both up with a smart 25A smart charger.
What would it take for me to change to lithium safely so that I can get a decent 80AH to run my fridge etc?
Can I put the lithium in the engine bay? Can I use the Anderson plug in the boot for the lithium?
Keep using your lead acid battery as they are more tolerant to heat generated in the engine bay.
Traditional AGM (Absorbed Glass Mat) batteries simply don't handle the high-heat environment of an engine bay. They’d degrade quickly, cutting short the battery’s lifespan and reliability. Some new AGM batteries have high heat tolerance and are specifically built for engine bay and high heat environment.
Lithium batteries fall in the same category and therefore not recommended for engine bay.
I have lithium in engine bay. Needs charger with Lithium charge profile, like Redarc BCDC1240D.
I doubt a cheap LiFePO4 could handle the heat of an engine bay.
it can, LiFePo4 is very resilient chemistry. There will be capacity degradation, but if you factor in that high temps are just 10% of all time, I'd risk to say battery life will go from 8 years to 5.
Goes without saying it does not replace starter battery, not enough discharge current, only as second battery for fridge.
You're pretty much right.
I've had a LiFePO4 battery in my wife's car for over 5 years now and it has been fine. However it has a supercapacitor in it to start the engine, so as a starter battery, it's not having a hard life.
In my car, I'm running a 105Ah LiFePO4 as a starter battery. It has a supercapacitor attached as well, but I only have it connected 50% of the time as I'm sometimes using the supercaps for something else (such as having it connected to a solar panel, so the fridge inrush current doesn't get too much).
Both cars are perfectly fine, however neither of the are off road 4WDs that run at high power and minimal airflow. If this was the case, LiFePO4 would not last that long (google Stefan Fischer's saga for more information).
But it's worth noting that under those conditions lead acid batteries will fail much quicker than they normally would as well.
Plenty of people put lithium in their engine bays, but I wouldn't.
Those who tend put it in as a second battery and leave the starter.
What do you drive? I'd just be putting the battery near the fridge in most cases.
It does have a smart alternator
See if you can get this turned off. Depending on the vehicle, it is pretty straightforward with the right software. I turned it off in my Ford Ranger.
so I find I have to replace the deep cycle every 3-5 years
Thats pretty good. I only got 2 years out of mine. I thrashed them with an inverter as well as some other 12v stuff.
charge both up with a smart 25A smart charger
Because you have a smart charger, it'll adjust the current/charge rate based on your battery %. So if it is 100%, it'll just lower itself to the minimum charge rate to maintain the 100% charge.
Can I put the lithium in the engine bay?
I wouldn't put the battery in the engine bay due to the heat factor.
Can I use the Anderson plug in the boot for the lithium?
Possibly, depends on how it is all wired. I have run a cable from the main battery to the canopy, where I have my charger and battery. You want the charger as close to the battery as possible. Don't have your charger in the engine bay, then battery in the boot. You will get voltage drop on the cabling which is not ideal.
Make an offer of 180 then apply the $10 coupon code. Down to 170, worked for me :)
Definitely don’t want this under the hood. But would be good if you have rear tray or draw system.

No Delivery North of Perth, Classic
@Tiddles155 I bought from this seller before and this one below. Same battery by looks on it. I'm North Perth. Joondalup area.

$188 delivered.
Ah im in Geraldton, and have had friends buy from the seller in the past but no longer, I guess. I asked them and they just said their courier doesn't deliver up to us, i assumed they would just use Aus post but i must be wrong.
Ahh ok, ordered from other mob. $183 delivered. Already got tracking from aus post.
Also got batteries from this seller before. Quick delivery and working fine. Mine was gentrax batteries. Between this seller and fab-living believe it was.
