James,
All points agreed upon regarding benefits of Nickel-Iron batteries, they
appear in almost every respect to be a solid choice. From my research, it
appears that Edison (Ni-Fe inventor/advocate) demonstrated the battery to
his pal Henry Ford but was unable to get Ford too excited about it for
reasons unclear. Too bad, it certainly would have served us better if Ford
had seen the benefits clearly, perhaps he was concerned about how much extra
cost it would add to his fast-selling flivvers.
As mentioned in a previous posting, beutilityfree.
for their advice. They are kind enough to charge it out in 15 minute
intervals they tell me. So much for good ol' fashioned customer service, I
guess it went out the door along with the smile you used to get when someone
took the opportunity to go beyond the call in the interest of best serving
the customer. Nowadays, the only smile you get is when they inform you that
they are out of stock or unable to meet your requirements. To companies
like beutilityfree.
earned it.
Each 6-volt module weighs 42 lbs. dry and 52 lbs. with electrolyte according
to the manufacturer'
unaffected by discharge rate, suggesting a low Peukert's effect, e.g., 209
amp-hours at 40 amps discharge versus 195 amp-hours at 200 amps discharge.
That's only a 7% percent change in capacity on a five-fold increase in
discharge current. The module dimensions are the same as a standard golf
cart battery for a straight swap-out. pretty slick! These batteries show
no sign of ever being used, so they may be the start of a great EV project,
I would consider selling them if interest was expressed (I have 28 off them
in total).

They where somewhat common in railroad and telco use. Email these
folks for care and feeding advise: http://www.beutilit

Outside of the need to keep them watered, they should last forever.
These really should be the batteries that you and I have in our cars
for starting, but about 80 years ago some auto executive decided
everyone could just buy lead-acid batteries ever three years instead
of paying twice as much for the first battery and it lasting the life
of the car. Sigh
Costing us all six times as much in the long run, and polluting the
world with tons and tons of lead! ;-)
These would be my second choice in battery technology for traction
application after LiFePO4. The LiFePO4 win out on weight and upkeep
like lead NiFe need regular watering.
But NiFe win out on longevity, They can be 100% discharged with no
harm! Not many other chemistries can say that!
Good luck with them. How much does each 6v cell weigh?
