Sodium iron not looking so great for camper vans .

Lithium LifePo4 12v Batteries - Time For An Upgrade?
- Thread starter Dellmassive
- Start date
What I take from that is they're not good for house battery at the current state - they're bad at emulating a deep cycle 12v battery.
But then so was LiFePo 5 years ago but now most kit is aware of how to charge and load them these days (so long as you buy the right stuff) it seems to me a lot of the charge problems at the start are chargers not being aware of the charge curve and that they could start a lot earlier.
I think he's right though, for more standby loads they look good, will be interesting to see what the lifetime is like. Be nice to have a 10+year lifetime starter battery for start stop.
Also yes LiFePo low temperature can be handled by various heating techniques, but in some situations an inherently safe low temperature technology is going to have advantages.
I also think in some situations the flat curve of LFP has it's issues - it's very hard to tell the SoC without current monitoring. Some times knowing a reliable SoC may be worth the other downsides

Don't buy cheap lithium batteries !!!

nice . . .
Anybody else think that looks like he's got a tape stuck in the VCR?
Other thought is that looks rack mountable ie why stick at 100Ah rather than wafer thin convenience.
Looks like the Yanky Battleborn lithium battery's have a design floor.
That they are trying to say is a "feature"....
I'd agree with will..... It's a design floor, and a bad one at that.

That's Will off their Christmas card list! I'll stick with Roamer! Fascinating videos, thanks Dell!
Yes...I put one on the solar panels input, belt and braces.
Didn't put one on the B2B input from the starter battery but realistically that might make sense so you can work on your system, mine just has the original VW fuse under the seat.
Just re-read your post and yes I've got a Victron IP22 30/12 that runs from one of the EHU skts on the side of the fridge housing behind the driver's seat.
Edit 3 and received wisdom is to not leave your lithium battery at 100% full for months on end but to run something to take the battery down to midway if you're not going to be using it, similarly trying to keep the capacity between 20% and 80% as with an EV.

Depends what generation Transporter you've got but after late 2025 when the Euro 6 class came in ie. Adblu then you've got a smart alternator which spends a lot of it's time doing bugger all so yes you'll need a B2B charger that converts the occasionally busy and sub 13.8v alternator periods into charging cycles for your leisure battery, a split charger won't do this and would only charge when it gets a high enough trigger voltage.
My 2019 camper conversion of a 67 plate T6 by Redline (bless them) still had an old school split charger setup that killed two leisure batteries in three years, on the plus side it was simple to swap the split charger unit for a B2B unit.

2015?
Senior moment there...
I'm a bit of a Renogy fanboy but their DCC50S will take a starter battery input and a solar input too to act as an MPPT, will provide up to 50A output but if running both inputs will split the inputs to limit total output to 50A... saying that you can dial back the output to a calmer 30A so everything can run cooler.
The Renogy will work with all battery types mine's on a Roamer seat base lithium iron phosphate type.

No isolator, I’m not a fan of them unless absolutely necessary. The solar is permanently on, so keeps the battery topped up. My battery has a “sleep” feature that basically shuts down the battery and isolates it from the outside world, never used it.
I have a 2016 T6 DSG
Get a 200 or 300Ah Renogy core duo battery cos I keep getting Renogy ads after buying other Renogy stuff, their batteries seem pretty good value for the amount of capacity eg. 300Ah for £419, bonkers.
Very happy with my Renogy 100ah after three years. Solid.
Mine lives under the drivers seat so ill probably have to stick to a 100Ah battery.Get a 200 or 300Ah Renogy core duo battery cos I keep getting Renogy ads after buying other Renogy stuff, their batteries seem pretty good value for the amount of capacity eg. 300Ah for £419, bonkers.
The Renogy 100Ah does look very tempting so will probably go with that one if people have good experiences with them.
