LIFEPO4 Battery discussion thread

I much prefer scientific studies tbh
Temperature has a big impact on these batteries. 30c or even 40c has a big difference on degregation compared to 20c. Temperature is influenced by ambient as well as how hard they are used in C for discharge and charge. Whether you routinely take it down to 0% is a different discussion and I have seen some scientific papers on that. I have my views and they don't agree with wingnut
 
makes sense but your cycles drop drastically. Could be the difference between replacement every 10 years or every 20 years. I was more surprised the battery doesn't lock up as I've been told passed a certain point they do and you have to take them in to get started again.

Whether that's sales snake oil or not I don't know, but would rather not want to find out.

Are you telling us that calendar aging is a myth?
 
but you don't agree that calendar aging is more relevant than cycling?
Nope , because aging is going to happen. On top of that is the extra factors such as temperature and cycling. So just basing only on aging is ignoring everything else on top where aging is a constant
 
Was away at Zimbali gold estate for a company team building last week. Damn the company holiday home has a badass system.

Luxpower inverter is also a thing of beauty, 3.6kW, 4000W mppt, built in wifi, generator port, very user-friendly.

I am considering changing my current 12v Fivestar 1.2kw inverter for this inverter. I currently have 2 x 100amp Hubble lithium batteries which I will rig in series for 24v, and I will have to add an equalizer. Do you think the Hubble batteries will be fine with the Luxpower 3.6kw ? I can't afford a new 24v lithium battery, so I dont want to waste my money on a new inverter if it's not going work efficiently. Thanks.

May I ask why you are considering to change to a 24V system, is it for future expansion? Because there is nothing wrong with a 12V system for small loads.

But coming to your Hubble batteries being fine with the Inverter, I cannot guarantee that, they do list Hubble in the battery compatibility list, I am not sure of the exact model of your battery.

Here is the list.

I have 2 of the Hubble 100 A series batteries, which apparntly are compatible when wired in series.

I wanted to go with a 24v system because I need to upgrade my office inverter to a pure sine wave inverter, so I could move my current 12v inverter to the office. The difference in price between a new 1.2kw inverter and a 3.6kw is approx R1345 including a balancer, so that would give me the option of a bigger load if I needed it. But, you now have me questioning my thought process :) Very seldom have I needed a bigger load, so R1345 toward our full solar system when we move, is probably more sensible.

Thank you, this is exactly why I thought best to ask more experienced people before I spent my money. I am going to order a 1,2kw unit instead.

I wanted to suggest that Luxpower also have the 1.5kW unit, nice enough to handle the surges even if your load isn't that big. My favourite thing about the 12V system is the ease of adding batteries.

100A x 24V = 2400W.

It will work but you're limited to 2.4kW load as I assume the 100A BMS will cut out.

I would rather get 2 extra 12V 100A and series 4 batteries with 5kW 48V inverter:
