Thread: LiFePO4 or Lead Crystal to replace AGM?

Peter
I agree it all looks impressive good on you
Just a question what happens in the heat? I live in a motorhome with a large bank of AGM batteries that are recharged by 1500 watt of solar
As this is my house it is all run 24 hours a day 7 days a week without much reliance on mains power,
In the summer months the battery temps can exceed 40 degrees C they are in the bins and in extreme heat there is nothing I can do about this ( I run fans as ventilation etc.
The only reason I didn't go to Lithium is their ability to cope with heat and the 20K cost of course

Hi djam1, well the environmental specs for my battery are -20 to +60 Celsius so that would cover what you are concerned about, but as you have said you have some ventilation fans in the compartment, very easy to set up on a digital thermostat so nothing to be concerned about.

FWIW I was looking at a lithium battery for my Harley and the battery world rep advised against it siting the problem with heat. Reckons there's a greater risk to fires with lithium and not much you can do about it. Apparently they go up quite spectacularly. "Best you can do is drop your bike and run!"

Thought that was more to do with how they are charged?

I don't know. Maybe as a storage battery for accessories would be ok. Told me that was the reason he doesn't use them in his race car. I suppose in a bike it's located close to all heat sources and directly under the crown jewels😱

Hi Marty and it pays to shop around for correct INFO as well as different brands.


In 2011 I was asked to test some Lithium batteries by one of the companies I deal with.


The first brand were absolute rubbish and I managed to stuff a couple of them with out really trying.


Then in 2012, after some assurances from another lithium battery manufacture, the company supplied me with a different brand and again, I carried out some pretty rugged testing with some smaller versions of this later brand.


The company then brought in a few much larger batteries for real world testing.


Only yesterday, the company informed me they are now going to market these batteries and are bringing in their first shipment of 100Ah, 200Ah and 400Ah batteries.


It will be interesting to see what prices they are going to be.


So again, Marty,shop around as there are good and bad in most products.

I understood that you loose a huge amount of capacity as the temperature rises to these levels 40+ degrees.
I may be wrong its a while since I read the results of tests done

I'm listening - especially to the price part.
It would be much simpler to pop down to the Gold Coast to collect a battery than have them shipped from Perth.
Will these be individual cells or complete batteries with cell balancing & BMS built in?
