...work at 100a? Is a potential fire in your van worth a £20 saving? It is essential that fuses work as advertised (especially the one from a lithium battery!) so personally I stick to known, quality makes such as Blue Sea, Victron, Littelfuse. If you want to keep the cost down then go for a...
we install Lithiums on their sides , keeps all the terminals and cables away from seat runners etc, we use a metal strap, and no issues with seat wiring
...pulling the charger fuse should be fine.
I think the voltage put out by the EC155 is low enough it actually wouldn't be enough to charge the lithium battery so in an emergency you could always turn that back on to support your 12v electrics if you had to. I'd just personally feel a bit...
...the below is clearer. If it is ok then I can just add a mppt when I get round to solar.
I take it just removing the fuse is not sufficient to disable the charger. Dumb question - do I need to wire the lithium charger in?
Thanks for advice on battery as I’m up in Aberdeen so temperatures do...
...one - can you get a clearer image of the top left?
Ideally yes you should disable the "charger" in the ECC155 as it's not ideal for a lithium profile and fit something like a Victron charger.
Remember with LiFePo you must have a low temperature cut off in all chargers or built into the...
...knackered. Am planning to add solar in due course so thought I might as well upgrade the DC to DC charger to one that can cope with solar and Lithium as want to avoid hooking up unless absolutely necessary. Current configuration is as per picture with a Sargent EC155 psi.
I’m no...
Afternoon - Hope everyone is well. Has anyone recently installed a lithium leisure battery on its side under the drivers seat and how do you secure them? I'm at that stage of my conversion now. Any info/pics would greatly appreciated. Oh and the seats are heated so there's wiring which I'm...
How far do you think I should go with a Lithium replacement?
My 2018 t32 t6 is a pop-top conversion which has a factory fit diesel heater and 75Ah leisure battery under front seat and an independently wired 105Ah leisure battery system (VSR, EHU mains charger and EHU) in the rear supporting...
...240v and 12v powered chargers are Victron I'm surprised they didn't fit a Victron MPPT controller.
That might be a consideration for the future as then you can see what all your chargers are doing in the same app.
It also means you're well placed for an upgrade to lithium batteries in the...
...and that looks a bit better than a blanking plate - as indicated above, the thing that's there now was a waste of space even before I went lithium. In the longer term, I might put something more useful in the space but anything involving charging would necessitate upgrading the wiring and...
Using a voltmeter to measure the remaining capacity of a lithium battery is pretty pointless due to the way a lithium battery discharges. The only realistic way is to either use the battery BMS if it has the facility, or an external shunt.
...which it was fitted when I got the van but TBH was pretty useless with the old AGM battery and is even more so now that I’ve upgraded to Lithium – this one:
I was going to replace it with this:
C-Line Blue LED Battery Voltmeter Display w/ On Off Switch Camper Fits CBE CL3.8 | eBay...
...power with 2x separate Victron units - but you get a much smaller and compact system.

Any of the above will also be lithium (LiFePO4) compatible if you decide to upgrade the battery, which the split charge relay isn't.
...arches yet I will tidy the cables up too at some point
There is a big void behind that panel to run everything and there’s an earthing stud available
The battery is a 100 ah lithium which fits perfectly
I’ve used the original fixing holes too as the ply panel I added fits inside the original...
Ouch.
So there it is going behind the panel presumably currently moulded together with the red wire which must go off to the smart alternator via a crimp connector or something. The manual says both wires are all of 20cm long! The positive battery terminal is currently at least 30cm away.
One thing to check if you are going lithium is you need to find where the battery setting wire from the CTEK is as that will need changing to change the charge profile.
Make sure you can find that while you have good access.
...if you've got the Fogstar by then they are a popular option and you could move it on in the forum quite easily.
And for a confidence boost @NicolasH was kind enough to post an update on a very similar change they did...
...of mind knowing you can go for days without having to worry about running out of charge, and damaging the battery.
By the time we had driven the 80 miles home it was fully recharged.
If anyone is thinking about upgrading to a lithium leisure battery, go for it. You will not be disappointed.
After a lengthy battery diagnosis thread Newbie battery charger questions, this is a new thread to discuss the swap I decided to do - not without some big doubts about my skills.
So I am looking to replace my Yuasa L36-100 lead acid with a Fogstar Drift Lifepo4 105ah. You can see the...
Thanks for this, it's all very new to me so I'm starting at the bottom. I'm installing 240v electrics very soon, so on site will be okay, it's just the off grid side of things I'm unfamiliar with
