After looking at my data sheets, all of mine have resistance between .32 and .37, and all had a date of 11 on the side. I'd say those numbers are just fine.

That's the type of spread I would expect, what was the capacity range?

109-111Ah. I should've realized. My controller has been having issues, and it's sitting in my living room floor right now so I can work on it. I think you have to set the battery voltage, and it uses that and an internal reference to measure the current. I sure wish I knew more about these stupid UMOC440 controllers.

We could actually over think this thing...LOL

OK, Maybe the AC test might not reflect the DC test, but it might have some bearing on cell condition as manufactured and by that a grouping criteria.

Either way, I'm sticking with my plan.

1.Figure my average daily usage and by that my pack size.
2.Then oversize the pack 1/3 rd.
3.Buy from a known company.
4.Buy all pack cells at the same time. (maybe same batch)
5.Monitor cells in the beginning to find one that deviates, then install a monitor.

I am a car guy, I always watch my toys closely and do not abuse them.

If I lose a cell or two, It is my fault for ignoring advice.

Sorry sir, 130Ah batteries are no longer produced.

That explains why those of us who took receipt of 130ah cells recently seemed to get the crappy floor sweepings.

Finding replacement 130s in the future will be a total PITA ...

Anyone know why they discontinued the 130s ? It seems it was the "perfect size" for small cars with moderate range ... (my opinion)

My guess is that more people looking for smaller size cells were buying the 100ah's size, which had better energy density, and those looking for larger sizes jumped to the 180's, which also had better density. More cost effective to build fewer sizes.

Just to confuse things even more, I got this e-mail response from the US CALB distributor a month ago when I inquired about the future availability of the 130Ah cells:
"CALB still product SE130AHA model, we still have some stock in our Pomona, CA warehouse. Those cells were just arrived in 2 weeks ago.

Please feel free to contact me if you want to order.

Thanks,

Sorry to confuse you. Actually, 130AH battery is not general mass production anymore. We cannot promise the stock of 130AH ones everytime you want.
