About 3 weeks ago, I took a $550 USD punt. I bought 12 of these:
They arrived neatly packed today. These are Lithium Titanate batteries.
At $22 per 30Ah + shipping, these units are ridiculously cheap at about 70c per Ah. The going rate is between $2-3 per Ah.
These are rated for 300A charging and discharging, with a shelf life of 20+ years, and 30,000+ cycles. Of course, their energy density for both volume and weight is terrible, so they are totally not suited to EV or eBike use, but this is an experiment for off grid power. ONE of these cells weighs a kilo, and is the diameter of a coke can, and about 50% taller - and you need 11-12 to make a 24v battery
The only question now, is have I bought the deal of the century, or have I been ripped off? Right now, being at work, I couldn't even tell you if I've bought a 66 x 160 cylinder full of sand... But if this kind of thing interests you, stay tuned for my testing! (Will probably do a few quick tests tonight, but the really juicy stuff won't happen until the weekend.)
