Who? I would have thought you would have gone directly to them. Since they are in the US there is no need to use a middle man. Me thinks you got screwed. Demand a new batch and then send back the crappy ones you got. Do it before you can't. If that time has come and gone thanks for the heads up. But who sold them to you?

You need to read the thread I linked to, I did not buy the batteries, I'm reporting what others have recently received.

Aaaaaa! I thought it was YOU. So this is all third hand. I will go back and re-read the article.

A bit more clarity on the issue. I'd check with CALB in LA. When I get mine it will be from there personally. I will make the drive. I won't ship from China when I can get them here. I may still opt to go with A123 cells. Much more power. I'd rather have the power for a larger vehicle. That will be important. Also if I decide to race a bit. Well actually my wife but you know a few times down the track and it WILL make her happy.

Crappy cells and out of sequence cells are indicative of getting rid of left overs from other orders that never happened.

Dumping off mismatched batches.

What's really concerning is that the factory can even produce cells of such high internal resistance. Even if a whole batch is at .60 resistance for a 130 amp hour cell that's more than twice what it should be for that size cell.

They were from calibpower, at least mine were through a group buy but shipped to me by Keegan. The issues I've observed I'd attribute to rush/not caring about some small fry when dealing with $100K+ orders.

I will try to get some close up pics of mine this weekend. The case color difference, the way the seams are glued and even the factory data sheet to show all of you.

I may merely be worried about nothing, but it will take a year or two to really show up....too late

About the colors, is the difference as extreme as it seems in the pic? I looks like some are an aqua color and some the normal blue.

With mine the one cell that is sealed funny is a slightly different color and texture, and the ridges are at slightly different heights. The battery number is a low 8 digit, so I don't think it's a repair job, but one they found hiding in a corner somewhere forgotten. It's probably several years old, but if quality really is slipping, it may outlast all the others (IR is 2nd from bottom and capacity 2nd from top).

hard to see in this pic, center cell is darker.

"Hiding in a corner" LOL, that is exactly my thought too.

One additional small complaint. Do NOT take their cell measurments as gospel. 5 cells are 1/4" larger than they were supposed to be, causing me to re-do some battery box lining, thankfully not the frame.

As far as cell ampacity goes, I cant complain. All were WAY above their rating. The lowest was maybe 137AH. (130 nominal) But I am limited as to the weakest cell, but still over advertised rating.

CALB is the only manufacturer with a cell in the 130AH range, to my knowledge. It fit my car and budget nicely.

This is just a hunch, take it for what it's worth, but I can't help think that your difficulty to get the 130Ah cells might have something to do with the larger than what we expect as a difference from cell to cell. Whether it was a difficult to produce size or if you got a bunch of cells that were from mismatched batches or something. :Shrug:

Not that this is bad or anything, possibly just a plausible explanation.
