Li Time Cell Comparison (300Ah vs 400Ah)

[protectedprofile]

Did anyone notice the difference in the type of cells used in the Li Time 300Ah and 400Ah LiFePO4? I would like a 400-600Ah bank in my shuttle bus and right now a couple of Li Time 300Ah seems to be the cheapest option I can find. I was going for 100Ah batteries, but this looks to be a cheaper option. I noticed the cells in the 300Ah and 400Ah are different, what's up with that? .... and a large price increase for the 400Ah.

Yes, I noticed that too. 500 extra dollars for 100 extra amp hours?

Lifepo4 cells are available usually up to 280 or 304 Ah. There are some Winston cells that are larger, but these are massive in size.
So by looking at the pictures, I suppose that they put 4 x 304Ah cells in series. To make the 400Ah, I suppose they use 2 x 200Ah in parallel, and then 4 series of those to make 12v.

I don't know why they jack the price of the 400ah batteries so much, when the 300ah's are in the same case with extra padding.
