[RE-wrenches] Ni-Fe update?

[jay]

HI Ray,

I’ll add that they use lots of water requiring lots of maintenance.
Their efficiency is between 70 and 80%.
The reason that the railroad and telecomm have used them in remote applications is that chemistry doesn’t care about cold or hot. 


And given that they cost (95%) almost as much as a top end Lithium battery, I’d go for the Lithium if someone has that kind of cash to throw around.

I've never sold them for these reasons, but I have replaced some sets that customers were unhappy with.  They seem to work OK, only if there are no large surge loads, and the battery and array are sized large enough.  Unfortunately because of the cost, folks seem to really under size them, which only exasperates the above issues.

It does have its place, and I understand the train industry uses it because A) they have cheap on grid charging available, so efficiency doesn't matter, and B) they have telecomm type loads with very little surge.

>> Hi Guys, I have a potential customer inquiring about installing a pre packaged Iron Edison system.. I recall hearing strange stories about Ni-Fe batteries but don't recall the specifics. I have done a few searches with mixed results.. And have friends advising I run like a Rabbit.. Thought I'd run it by you folks for an update..
