Very interesting. These might make great batteries for an off grid system. Long life, lots of charge-discharge cycles and deep cycling are all highly important to an off grid application.
Don’t try to compare these with Lithium ion batteries though as these two battery technologies are really two different beasts. A lithium ion battery is extremely lightweight, very power/energy dense has a limited number of charge-discharge cycles and cannot be discharged past about 35% or it just dies. A lithium ion battery excels in lightweight, mobile applications. The lithium titanate batteries will shine in fixed applications that require lots of charges and deep discharges. While not great for a car, lithium titanate would be great for a house or cabin.
Well this is interesting. They sound great BUT 40 amp hrs ? You can't do much with that.
Now 400 amp hrs would be useful in stationary off grid applications.
I have not searched beyond the links provided yet, but I will. If they make this in large sizes I will be very interested.
No, I don't think that 40 amp hours will suffice for any dwelling sized backup. But if these are affordable, then a battery bankshould be perfectly doable. I guess we will have to see how these new batteries compare price-wise to AGM batteries which are presently the most affordable deep cycle batteries.
