Where to buy a Lithium Battery?

I’m just a poor retired plumber heating engineer and I’ve fitted 2 100ah Eco-Worthy batteries to my VW T6.1 Transporter conversion.

Just been googling them and prices are jumping off the screen at £1200ish for a 200ah one

My current battery is a Banner 100/110ah which is neatly hidden under the floor in the lounge area.

I want to just lift that out and drop in a lithium same size so I fully fill the space for max available power.

I am looking at all the other stuff which I posted in another thread re solar and chargers etc

Just thought quick question. What price should I / could I pay for one and from where?

Pictured below is the Banner 95751
Length 354mm
Width 175mm
Height 190mm

Reading the responses, it looks like nobody has given consideration to your available physical space. Most if not all of the fogstar suggestions are way too big physically to fit your space. This also applies to most of the other lithium brands - they may be a drop in replacement electrically, but not physically when your space is only suitable for a standard 190 high battery. And yes I know that you can lay a lithium on its side, but that only works if you have the space.
I have also looked for a drop in for battery which is the same dimensions as yours and struggled to find anything. KS energy do (or did) one that meets your size, but that was much more expensive than a fogstar and did not have heating as the fogstar does.
So, you may well have to rethink the straight drop in requirements and explore the options to fit it by altering you battery compartment.
Good luck.....

Looking at this measurements and at the picture.

Is that the height of the battery or the available space. If it is the battery then he may be able to squeeze a bigger one in as it doesn't look to fill the space fully?

190mm is the height of the current battery. I collect the van tomorrow so I’ll be measuring what max space I have to fill
 
Also looks like it is in a false floor so a modification to the lid would be possible if height was the only issue?

One benefit of Fogstar is that if you can get to them and they have batteries in stick, you can try them to see if anything actually fits without it costing anything!!

I purchased one of the first Roamer battery's, over two years ago and have been very happy with it, not sure about the dimensions though

Quite true as far as size and all excellent advice above but the point most were making was the price compared to what the OP had originally quoted and had not seen the fogstar range

I converted my van and used it for 7 weeks in south of France September and October.
I bought a Roamer 12V 400AH battery. £1700.
Great value
Once charged, it runs the van for 5 days or so. Not tried pushing it further. It is so efficient that I didn’t need solar charge so I will be taking the 500watt solar panels off the van for the next trip.
Battery charges from alternator and hookup when on site.

Go big
Go expensive
Saves any hassle and saves money and weight of solar.

Roamer are English firm based in Yorkshire although like most batteries they are made in china and imported, but at least you have uk based experts to speak to.

Not sure I fully understand this comment Gary, you’re removing the solar panels as not needed but using site ehu to charge your battery up again? 🤔

Surely you’re solar will do that for you won’t it

I’m curious, are your 500w panels fixed to the roof or suitcase type?
We did an install for someone on Friday and as weight was a big consideration we left a huge part of the roof without panel. We could easily have fitted around 300w or even more if weight wasn’t an issue.

Yes, may sound strange, but we stayed on campsites 3 days a week and with one night hookup, the battery is fully charged so solar is just not required. I didn’t use the solar once whilst I was away.

If you have a small battery, then I can understand needing to charge it every day, but with a big battery, it lasts a week and runs everything. That was my point.

I spent £1700 on a 460Ah battery.
You could buy a 100Ah one for £400, but then you need to buy solar panels. They are £2-300 each for decent ones and you would need very good ones for low sun days. They do not work that well if the sun is not directly overhead and cloudless skies.

I think, for me, better to have a larger battery that lasts 5-7 days on one charge.
I don’t know many people who go off grid all the time? If you wanted to be off grid permanently, you would need big solar panels, and even then they would struggle on a cloudy day unless you were driving as well.

I hope that makes sense

What do you think?

I’ve already got 560ah of fogstar lithium so understand the needs for charging them to the max 😉👍

I have 3 x 250w panels, of which I only fitted 2 on the roof. There is room for the third but I figured as I was going to south France, I would not need 750w. As it happened, I didn’t need them at all.
They are big, and heavy. The weight, being on the roof is in the wrong place really. You don’t want all that weight on the roof for the stability of the van.

I may buy a portable panel for emergency use, but it is just easier to stay on site for a night, hookup, and charge the battery for the week.

As part of my set up, I had to let all the charge out of the battery to sinc it with the app monitor. I had the fan on full power, the fridge and chargers working day and night for 2 weeks to drain the battery.
If you get a big battery, you don’t need solar. That is the only point I was making. May not be right for everyone, but worth thinking about.

Right now with Black Friday deals £1500 is quite expensive. Amazing how prices have come down so much in just a few years.

Sounds like now is the time to get a bargain then.
£1500 on a UK backed battery which will run everything in your van for 10 years is not a bad shout. If you can get a better deal, go for it.

fair point I spose, huge battery bank for small usages versus cost of colar ad all associated addons. Whatever suits you versus payback I guess. (and weight)

Myself I like to have the solar and battery bank (400ah) which at the time folk were saying overkill :rolleyes: but I do sometimes even pull onto a site pitch and dont even plug in

Sounds crazy to me, why pay for EHU when you can charge them for free with solar.

Just for full disclosure we sell LiFePO4 batteries, so my “better” deal would be from myself 🙂

On the subject of UK-backed batteries, pretty much all UK sellers will back their batteries up In the UK. Virtually all LiFePO4 cells come from China (there are a few specialist manufacturers in the USA). The vast majority of BMSs also come from China. Quite a few of the battery suppliers and sellers I know in the UK use JK or JBD. Sellers such as ourselves, FogStar, Roamer, KS, Ecotree etc will back it up here in the sense that any hassle will be sorted here without the need for you to go to China.

Of course if you buy cells from China to save some money, then if you have a problem it’s very expensive (£100) to send the cells back. Maybe that’s what you’re alluding to , and if so you’re correct.

Me normally but did stay on a site in Spain for a few days in April, it was cheaper without EHU than the ACSI rate so obviously didn't have EHU.

A few months ago we stayed at a site in the New Forest, didn’t pay for EHU but wouldn’t have minded it. Rained the whole time so solar did zilch and we used so much power on the rice cooker (prepped meals for three dogs), coffee machine and air fryer. Came down to 20% which is about the lowest we’ve been for a long time.

Plenty people on this forum go off grid as much as possible, as we do. Relying upon EHU limits where you can stop. MHF rallies rarely offer EHU. And when you get to Europe plenty of free and cheap motorhome Aires to stay on which don't have EHU.

Once you have solars it will be the only source of free energy you will get
