Two more pretty Lithium batteries arrived today.

[Admin]

Yep i read all the blurb before i replied previously but the cost difference still outways the advantages in my eyes


Crikey my pair of Varta LFD90’s are 10 years old and only 1/10th of the cost at todays prices

Would have to live and continue motorhoming for a heck of a long time ( 50 times 10 years mmh!)

Yes if I had loads of spare dosh I would probably consider buying them ( I managed to justify to myself the cost of an E&P levelling system )

And i always take new product claims with a pinch of salt , will these new technologies really last as long as they claim?

Eg off topic but shows how a new product can make false claims

Many years ago I bought new bathroom taps which came with the latest new Ceramic inserts claiming that i will never suffer from a dripping tap again - soon proved wrong as these ceramic cartridges found in most taps these days can start to drip after a couple of years

The lifepo4 technology in these batteries has been tested and proven over the past 22 years (when it was invented).
I agree the cost is high, but to be honest, motorhoming is not cheap. For someone who uses an inverter, one of these batteries could do the same job as four 100Ah batteries.

Could you confirm the charge temperature range with them as well? I know it quotes -20 to 45 Charging, and -20 to 60 Discharging in the specs, however the charts for the Charging shows examples of 5C to 45c, whereas the Discharge one matches the spec sheet with examples from -20c through to 60c. -20c for charging is pretty unusual for Lithium and I am wondering if that -20c in the spec is a typo!

They do a RB100LT that charges down to -25c maybe the low figure is from that one?

The data I have for my RB100 gives a discharge and storage temp range of -20C to +60C but a charging temp range of 0C to +55C. I think it is the new RB100-LT that can operate at -20C but charging only really starts when it has heated itself up to 0C. There is an explanation here:

Some interesting reading on this thread

 

[trevskoda]

I have just twiged if i fill lead acid guts inside these new fangled blue cases and charge 80% of price i should be a million up before xmas.

Hi Phil. I've been told that in order to go lithium I need a B2B and an MPPT solar controller, are you saying that I don't need these and your batteries are a direct replacement?
Thanks.

I read this article when thinking about buying a LiFePO4 battery but the negative arguments didn’t convince me. It is an opinion and there are many to be found on the internet, it took me weeks of digging and research before I reached my own conclusions. I am very happy I went ahead with the purchase but it will be many years before I can make my own objective assessment, which is what is lacking in many of the opinions. I would not argue that an expensive purchase like this is for everyone but the performance and reliable supply are what I was looking for. The only firm advice I would offer is not to make a decision based on a single opinion.

I have removed the post from here about lithiums because the data in it is nothing to do with the batteries that we are discussing in this thread.

I found a B2B a great addition to my LiFePO4 system but it is probably not essential. If you have a solar system then a controller with the correct charging profile would be my choice. Not all MPPT controllers have lithium profiles.

I thought it was a very interesting and appropriate article

i dont think you should censor articles like this

The information in the article does not relate to the batteries we are talking about in this thread. Posting it in this thread may make people associate them together. I could go through and list the issues but the battery companies have already done that and allegedly, he is not prepared to correct the data in the article.

Then its ok for Mick H to open a new thread with aanddcaravanservices thoughts on lithium batteries ?

Yes sure, I am happy for Mick H to express his thoughts on lithium batteries or to talk about someone else's thoughts.
However, I am not happy to give a free search engine boosting link to a website that gives incorrect information about lithium batteries.

So to clarify:

Make posts on this website about any motorhome related topic - YES
Link to give free traffic to other websites - NO

With respect, Phil, that is just your opinion.
The technology of Lithium batteries, for motorhomes, is too new to actually know if they are better. Time will tell, so perhaps you will tell us, in 10 years time, if yours have been cost effective.

First, Mick, I must point out that I have AGM batteries in my motorhome, these batteries are not mine. I ordered them as a favour for one of the members to get a trade discount for him. I have then transported them up to the Botany Bay meet for him. I cannot afford to change my batteries to lithium.

This technology has been around for 22 years. The 6000 cycles at 100% of rated capacity discharge of the RB100 is proven and certified. But the fact is that this is not the most important feature of lithium batteries.

Phil I must admit i was under the impression you were fitting these to your own camper

“to a website that gives incorrect information about lithium batteries.”


aanddcaravanservices writing a load of rubbish then ?

They must be correct on one feature in that lithium batteries have been known to catch fire

Thanks for your reply. I must say, I am confused, I thought that you were having them yourself. Do you know of anyone, in the Uk, who has had lithium batteries in a motorhome, for any length of time?

Those are lithium colbalt batteries, these are different. If you look back in this thread you will find the safety sheet for the Relion batteries, you would have to try really hard to get these batteries to catch fire.

They are not the least bit correct. The LiFePO4 batteries we are discussing here which are sold as leisure batteries do not have a history of catching fire. Lithium is a safe material, a good deal safer than either concentrated acid or lead. There are other types of lithium batteries that combine lithium with more volatile substances, to pack more energy into a smaller space. However this is a different technology for a different purpose and it is not helpful to confuse them. Kittens and lions are both oxygen breathing cats but that doesn’t mean they behave the same or pose the same threat.
