As far as I know Tesla actually uses Li-ion batteries in packs. Did you ask for the price??
Li-ion batteries typically get hot at anything above 2C. (meaning that if the battery is 3AH it will get hot at 6Amps load)
And they don't last for ever, it's the same type as the ones used in laptops. 3-4 years and you'd need new ones
Also these batteries need a lot of safety arrangements.
Only yesterday. Got a quote from one company and waiting on another.
My idea is to be completely carbon neutral and be able to live off the power I generate most of the time. Obviously, on cloudy days, where I’m not producing solar, the battery won’t be able to get enough charge for me to supply all my power needs at night so I will still be on grid and able to draw from the grid when needed.
Tesla is one of the batteries I’m looking at. Yes they are Li-ion.
The batteries don’t last forever but neither do solar panels. They typically last for 20 to 25 years. Warranty is for 10 years.
You recoup your costs within 3 years. Do worthwhile exercise even if you have to replace every 15 to 20 years.
The way things are set up in Australia, you can get an electricity credit from your power export rather than an electricity bill if you export to the grid.
My average power usage is 22 kw per day. The battery options are 6.5 kw or 13 Kw. So I can get half my power needs from the battery which comes from solar till the battery is fully charged and draw off my PV and pretty much be self sustaining.
I wanted to add more panels too but if I do that, I lose my Feed in Tarif which is extremely generous.
I have always loved new tech and always seem to be an early adopter.
