The 45 x 200ah cells I have fitted in my Landy = 3.2v x 45 = 144V x 200Ah = 28.8kwh . = 250kg

Hypothetically, 28.8 x 3.5 = 100.8kwh = ~ 157 cells @ $200 each = $31.700 = 875kg , 100kwh would give my Landy 280km range , not taking the extra 625kg into account , but would certainly take me over GVM.

(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.....

I think the only thing cooler than this build would be an EV 101.

Yes Tesla have around 7000 cells but around 3000 would be enough for my Landy.
That power wall project sounds cool, tedious but I'm sure will be very rewarding . What are you doing as far as a BMS ?

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.
