The issue with the PFC charger was corrected shortly after I complained.
(I complained bit too loudly and publicly in retrospect. I apologized
then and I do again now.)
You can now set the PFC charger to "latch" the end-of-charge timer and
not reset.
It is still a very good idea to set a maxim

Thanks for your reassurance, David and Evan. I'll try charging them in a
24-battery string, and see what happens!

Hi David, I typed "pfc restart" into gmail and amazingly it came up with
the post I was thinking of, from 2005. I hope Bill doesn't mind me
reposting it. There was a very long discussion leading on from this too.

Rich will likely disagree, but there is a subtle, but very serious design

Nope. And if I had any, I'd be using them. :-\

Got any STM5-180s? Or 200s? I could use 36-40. Good ones that is. Dach

I doubt this too. I've never heard of these cells being damaged or
overheating through *correct* charging, although I'm only familiar with the
water-cooled variety.
I have heard of one Saft pack being cooked. IIRC it was a Manzanita PFC

I've heard of this happening from gross overcharging, but NEVER when they
were "charged to spec" (in accorda

I've had an early 10kw for 1.5-2 years. Bought it assembled. It blew

Thanks for your detailed response, David.
I do have the tech manual you referred to. I understand the single-battery
charging regime.
My concern is equalization. The person I got these batteries from fried
individual batteries -- I mean internally melted! -- by charging them to spec

Hi Jay, and welcome to the EVDL.
Here's the technical manual for Saft STM-180 batteries:
http://www.evdl.org/docs/STM5-180tech.pdf
Unlike some of Saft's other NiCds, I'm pretty sure these were designed for
road-going electric vehicles. They were used in the Chrysler TEVans, if I'm
not mistake
I have come upon a 26 kWh set of SAFT 4.180 flooded-cell NiCd batteries.
These are industrial quality, and should last a long time, if properly cared
for. But I know they are subject to damage if over-charged. All the BMSs I've
seen are designed for lithium. I have the manual, but I'm worried ab
