I wanna know, if you have this battery which has very long life of 20,000 cycles, can operate from -40 celsius degrees to 60 celsius degrees, can charge and discharge at 10C and 30C rate, doesn't catch on fire or explode, but cost 5 times more than regular LFP batteries, will you consider using this battery for your home system?

    What do you have??? I'm guessing, nothing.

    First you would have to establish a "regular" cost. To date I think there is 1 LFP battery with UL1741, though this would not require insttallation inside (or heated space). About $300 a kWh, so you are saying $1500 a kWh that's a pretty large jump.

    I would need 12 kWhs of effective usable range, so $18,000. More than my current total projected system costs for 20 years, and I'm 10 years in...

    Charging at only 1200 watts (C10) would be a 'non starter' for most off grid solar electric systems. Edmond said:

    Need more info on this... so a 12 kWh could only discharge at 1/30th or 400 watts?
    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.
