How many of those batteries would you need to compete with a tesla 100kwh battery pack?
The 45 x 200ah cells I have fitted in my Landy = 3.2v x 45 = 144V x 200Ah = 28.8kwh . = 250kgQuote:

(Tesla batteries have denser power per weight & about half the price. )
It would be much cheaper to buy individual Tesla style 18650 cells and make holders / brackets enclosures for them, spot weld the connectors / but my minor form of ADD I could not bear the thought of assembling around 3000 cells .
Pretty sure the telsla cars have around 7000 cells in them. I am currently disassembling charging and discharging around 1500 used 18650 cells to build my own Powerwall for the house. I am promise you it's not an exciting project after the first few hundred.....Quote:

Yes Tesla have around 7000 cells but around 3000 would be enough for my Landy.Quote:

Probably end up going with Batrium like most other diy Powerwalls. It's a bit pricey but it's always a pretty flash piece of kit. Also nice that it's an Australian product.Quote:
