These averages come from much much higher quantities, and are not retail prices.
There's also such significant demand that at the retail level, it's unlikely that you'll see < $150/kWh anytime soon, I would think.
As batteries get cheaper, the potential market also gets much much much larger. At $275/kWh it is pretty attractive for a huge part of the consumer market, and almost no one knows that batteries are that cheap already.
Really looking forward to a future with cheap energy storage and super cheap energy generation from solar and wind. It will enable a huge surge of productivity in the global south, especially if people can electrify without having to use super-expensive grid transmission systems.
i mean the lead acid in comparison seems dirt cheap, somewhere like INR 15000 for a 200ah12v which is 2400kwh or $187~. that is like $78/kwh so paying 3.5~times more for the tech is too much right now. i mean, sure there are benefits of longer life and deep discharge but the upfront cost at good quantities is too much. so if i had to get say 20kwh, or 48400 that would be like $5500 or inr440000. compared to a similar lead acid 19200wh, 12200*8 at inr 120000 or $1500. that is a large delta. i could be wrong in these rough calculations though
Lead acid has far fewer cycles (500 typical) than LFP (5000 typical) so if you look at the prices per kWh out from the battery LFP is way cheaper (and lighter).
Even $250 per kWh of LFP storage with 5000 cycles means 5 cents per kWh out of the battery.
And in reality the cost is even less since after 5000 cycles the battery will still have 70-80% of original capacity and can keep going for more cycles.
i can get 200ah for this price for same 5 years warranty included and no shipping. its sold at the shop on the other block so shipping and warranty is included.
oh, btw you cant really buy stuff from china to india. the borders are either closed or you have to pay 40% customs so that is out of question. the reason why i think LFP at 275 is expensive , again because the replacement before 5 years gives me another 5 years without paying again so essentially i would be getting for $1500, 12 * 200 * 16 and sure its bulky AF but i do not have to drive more than a mile for getting it to home so yeah
uh, this one says
Long cycles (1500 @80% DOD, 5000 @ 20% DOD); AH efficiency > 90%; WH efficiency > 80%
sure 1500 is not 5000 but its also not 500. second, it says 60 months warranty which they mean "replacement" so if i exhaust the 1500 in 5 years,they would replace it at no extra charge, suppose it happens after 4 years. the new batteries would give me another 4 ~ years so in total i would get around 5+4~5 years life out of paying just once.
i'm not saying LFP is bad, just expensive.
Price is 215 USD for 12x150 1.8 kWh (and 61 kg) looks very expensive to me for a very short lifetime (5000 at 20% DoD means 1000 cycle). (I assume shipping is free or do you have to pay it for warranty ?)
I paid $100/kWh for LFP 3.2V 280Ah cells delivered from China to my country in Europe.
