Difference between CALB Batteries

[kevfab]

I am new to LiFePO4 batteries and am considering building my first DIY battery. I am trying to figure out the difference between the White 100AH cells and the blue 200AH other than physical size and color. If my goal is a 200AH battery, It seems that 4 x 200AH cells is both cheaper and takes up less total volume than 8 x 100AH cells. Can some of you experts help me figure out if there is a performance difference between these cells.

I am trying to figure out the difference between the White (grey) 100AH cells and the blue 200AH other than physical size and color... Can some of you experts help me figure out if there is a performance difference between these cells.

Thanks in advance!

I've got a thread on that topic here. Its worth checking out, I found datasheet for both the Blue (SE series) and Grey/White (CA series), as well as a simple comparison chart.

Thanks Dzl. I didn’t see that thread. Sorry to double-post the same question.

I reached out to CALB USA, I'm waiting to hear back from them, I'll post the their response in my thread on the topic, and here too if I remember to.

I asked the question to the seller of battery warehouse. The answer was that between the grey 100AH and the blue 200AH is almost no difference in the battery chemistry other than housing.
