Thanks, just thinking they would run a long while on non ehu
I think he is little bit selective in his comparison with his favoured Victron Gel. Victron also make LiFePO4 batteries and the following is lifted from their own web pages:For a sceptical expert viewpoint - but independent, they don’t sell batteries - maybe worth looking at this source: http://www.aandncaravanservices.co.uk/lithium-batteries.php

I would say for most people LiFePO4 probably isn't worth it.
I went for it as I use a lot of 12v power everyday. Besides holding more power in a smaller, lighter space, my cells charge faster and more efficiently than other types of battery. As I'm rarely on hookup this is a massive advantage.
To give a real world example, in my last build I had 4 x 100Ah lead acid batteries, 2 x 100w solar and a very good CTEK charging system. I monitored the system with a BM1 monitor.
I had a (low power) PC running most of the time and a compressor fridge. Without sun, after 2 days I'd have to switch the fridge off to save power (need PC for work).
Now I have a 400Ah LiFePO4 battery, 4 x 100w solar and very good Votronic charging. I can monitor the system via my phone or the chargers screen. But I don't bother.
I power a 12v PC, compressor fridge, router, MaxxFan and a few other bits all the time. I don't ever turn them off. When there's sun I'm completely self sufficient. Over the last month I've been parked in the shade, apart from a little sun from about 4pm. After about a week I have to remember to plug into hookup for a charge.
If I forget to charge my cells it isn't an issue as they are protected from damage via low voltage and shut everything down. I've only been using LiFePO4 for about 3 months, but so far they have been amazing.
Weight is one advantage of your system i can see though, how much do the batteries weigh on your set up?
Sounds just like home, but before you stop somewhere overnight do you have to get planning permission?I need a decent inverter in my camper. My wife uses a hairdryer, so that’s that, in addition the camper comes with three large TV’s fitted, all mains, built in and way too big to replace with 12 volt. In addition, the Humax digi box is mains, along with the HDMI distribution unit, the surround sound system and other bits and bobs.

I’ve just replaced 2 x victron 220ah gel batteries (total weight 132kg) with 4 x victron lithium 90ah (total weight 64kg) thus massive saving on weight and also giving me 288ah of useable power compared to only 110ah with the gels (50% gels, 80% lithium’s)

Of course it does; sounds like it's the crème de la menthe Rodney.Yes plus the VE.bus BMS and I updated my victron MPPT with the smart one as I needed to use the VE.direct port to link it to the BMS so in the event of a detection of any cell been above a certain voltage the BMS shuts down the solar controller.

Wouldn’t it be cool if you could use the car as an extra battery source when off grid?Haha I have spent a small fortune on all Victron products but do utilize it a lot as I also charge my smart car when on sites which have limited hook up amps available so supplement it with solar

Yeah would be great, got 4608kwh of power in the lithium’s and for 17800kwh in the carWouldn’t it be cool if you could use the car as an extra battery source when off grid?
