It's not 1300 anymore. They're as low as 720. And if you go with 50ah, 450 for 2. Battery wars are bringing prices down
Links? Can't be much quality there for $720 on a 48V 100Ah.
Anyway, 280 Ah pack at $1800 is $6.43/Ah while 100 Ah for $720 is $7.20/Ah.
That is 10.69% cheaper. It can be even cheaper if you don't use the Luyuan box. $1800 - $330= $1470
That is $5.35/Ah which is 25.69% cheaper.
When you start building 114 Kwh banks, that 10.69% to $25.69% adds up. Take the bank I'm currently building, the box was $200, paint and material will put it at around $800 total. The JK's with screens 125 x 8= $1,000. Class T's were $60 x 8= $480. Luyaun EVE new cells at $74 (shipping not included) x 128 = $9,472. Cables and busbars another $300. Total = $12,062
Meanwhile the 100Ah server rack battery cheapie for $720 (need a link for that), will take 23 batteries (shipping not included) x $720 = $16,560. I would have no control over the quality. Take this
AO Lithum thread. You can have it, I wouldn't put that in my house or shop. I still beat it with the 114 Kwh bank by 27%.
In reality, the $1300 is average price for something comparable to what I build and 23 x $1300= $29,900 My box is 59.65% less.
If your income increased by 27%, would you accept it? How about 59.65%?
