is there a specific reason you're looking for LFP?
Not really. Whats your recommendation?is there a specific reason you're looking for LFP?
Thank you for your reply, I am not getting the same math results. A used pack OEM pack cost more than these new cells. If I could get one for a reasonable price like 1/2 of new I would consider it..any used OEM pack, tesla modules are most expensive ($200-300 per kWh) and others usually arount $100-150 per kWh
Thats interesting thank you.$5-600 per 100AH @12V is low market rate for new quality LFP prismatics.
Well maybe new, maybe good, from unkown overseas vendors.
Compare to a local trusted vendor, which of couse should be higher

That 4.1 V idea is interesting thank you. I have looked into that Tesla cells. They are $233/kWH. Do you recommend a source other than ebay?ebay prices aren't the best comparing prices.
tesla modules are actually quite nice for 120v, if you charge them to 4,1 volt per cell, you get 123v charged from 5 modules.
capacity of the '5,3kWh' modules is more like 5kWh if you charge till 4,2 volt, you loose 10-15% charging to 4,1V (something to calculate with), but you get a longer life at 4,1V (goes for all batteries, LFP numbers I don't know)
To what brand of cheap Chinese cells are you referring?
ultrafires? with fake 18650 cells
This gave me a good laugh. very amusing, never seen this before.To what brand of cheap Chinese cells are you referring?

i would recommend to not charge up to 3.65, many folks here have lost cells in packs due to charging just to 3.6. The resting voltage of a fully charged cell, 100% is 3.33, so even 3.4 would fully charge a cell and be less risky for loss."FORADEPOWER" Is an interesting one:

This sounds like the direction everyone is pointing me in.I like Volt Batteries
You can get a 16 kWh complete unit with all sorts of extra goodies for about $2000
They are a TON better than any of the "new" cells
