It is needed that LifePO4 battery suitable for common lead acid battery size replace, for more ecnomic and easy acceptable.

I'm not sure that's true. There are relatively few lead acid EV's on the road and since lithium will be smaller for greater capacity it won't be that hard to fit them. As long as the height of the cell is the same or shorter, that's the big issue. Obviously the smaller overall volume the better, but that is limited by the technology.

For warehouse in US now is being pushing by Lili He, My main purpose also is to offer the best common AH and size to her, and she would put that size cells in US as storage. but we are not so sure weather new size are wellcome, like 100AH cells, two sizes, need to be desided.
Best Regards!

I'd say the shorter, denser, new cell is the better choice.

If use Voltage multiple with AH, then divide by weight, would get energy density, as WH / kg

But you didn't publish the weights

now THAT is a cool idea, and probably patentable if you jump on it quick enough. It would be a big help keeping the block lined up while strapping. In fact i'll go ya one better... if each battery case had molded in inserts allowing end-plates to be screwed on.... no need for straps at all!

Doubt an interlocking groove is patentable. How would screwed on end plates compress a whole pack?

lots o room for improvement here!

If it adds cost and takes up space I'd say it's no improvement at all

Terminals / holes:

new module type:
100AH 10mm
160AH 14mm
200AH 14mm
60 AH 6mm

former type:
100AH 8mm
50AH 6mm

Cell Weights?

 

[JRP3]

Exactly, if we are to calculate density we need the cell weights.

Since the post above yours lists height, width, and length, it should be obvious they are prismatic cells.
