My cost for Discover AES has come down 5% from a year ago. L16 AGM are still 2 times the cost of L16 flooded which move around in cost normally with the price of lead. So, I would say LFP is a bit more than 2X flooded with a big however. The comparison is tilted because the 6.65 kwh (useable) A

Wrenches I would like to see the LFP price come down in price, I have seen some cheap POS's coming out of China $3800 for a 10kWhr battery but they have very little surge capability so the LBCO shuts down the inverter, Blue Planet seems to be holding on their price, Have not heard anything differen

I want to ask about the cost of lithium batteries. Tesla seems to be telling the market that LFP batteries are way cheaper than NMC, and that they are switching to LFP, at least in China. From what I see in the marketplace that’s a lie. So I want to know from the lithium experts what they mak

Jay, EV battery packs will always be less than the type we use in the RE industry. Chevy Bolt replacement battery in 2017 is $262/kWh according to this: https://www.greencarreports.com/news/1110881_how-much-is-a-replacement-chevy-bolt-ev-electric-car-battery Over the last 5 years, two brands we

Good point Dave. LFP has a much higher ignition point than NMC and that added safety is often deemed worth the added weight for stationary applications. Not sure about resi-scale costs but Adara has a nice C&I product priced in the range you mentioned Jay, but including design, installation, comm

The Chevy, Tesla, Nissan are all NMC lithium. Residential is mostly all LFP except LG. NMC is about 1/2 the weight as LFP also. Different design goals is my take. Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ e-mail offgridso...@sti.net text 209 8

Hi all, I was doing some research on the Chevy bolt, and found that it’s battery cost about $145 per kWh in 2015. All the batteries I can find for sale for offgrid small systems ( 10-100 kWh) are in the $700-1000 per kWh Does anyone have insight into this. Or maybe better put, ways to buy a
