Lithium Titanate
Hi All, I got a quote on Lithium Titanate "Max discharge rate is 10 C so 900 amps for 90 ah and 1200 amps for 120 ah The 120 will be 30% more expensive than the 90. Price for 90 ah is $150...

So leading all this up to an innocent question...
What do thousand dollar batteries buy you?
Hi Mex,
Welcome Back!
In my case I'll go for SiO2 at $500 usd per 100 amp-hours. I want a large bank of 6 divided to 3 and 3. They can be used at -40. The can do 602 discharges to 0 volts, 1500 to 20% state of charge or 2800 cycles to 50%. They don't sulphate and need to be fully recharged once every 30 days @ 14.6 volts. Since I'm no longer full time--for me these batteries come with a lifetime guarantee.
My requirement is enough power to run an O2 concentrator overnight as I refuse to run a generator while sleeping. That is why I want 600 amp-hours of capacity. If I go with 80% then that's about 5 kwh of usable storage.
There is a firm in Lac la Biche that is selling a 100 amp-hour drop in LI with BMS for $313 usd. If I lived in the warm south that would be a good choice I think.
