Thank you Peterg7lyq for this most informative article. Well, from what I was able to gleen from it with my limited brain capacity is those batteries will not work for off the grid living, at least not by me. I sure learned a lot from your article, and I really appreciate it. I`m sure that much smarter people could make it work, but not me. I guess I`ll stay with my 6 volt wet cell batteries wired in series, it now seems so much simpler after reading that article. I have enough trouble running these ancient tube transmitters and tube receivers, and just keeeping power to my home here in the woods. Thanks for your input. Bob KC0VEA

Get some old fork lift truck batteries they can take deep cycle discharge and charge.

But if you do not run them deep they should last almost forever.

you can fit them with auto matic topping up you could make this simple device yourself.

you should be able to pick up these batteries cheaply enough good luck with your venture.

or golf cart batteries.

look for a "GC" size Golf cart or "FS" size floor sweeper

http://cr4.globalspec.com/member?u=39599 Well one2playwitt, gc batteries are what I`m buying. These new batteries are tall and kinda thin. I told them I wanted the large flat batteries that weighed about 200lbs. apeice. I`m not overly impressed with these new batteries. I think big and heavy is much better. These new batteries weigh about 80 lbs. Personally, the bigger, the more cumbersome, and just out right huge is what I want. I`m sure if I keep looking I`ll find some. Thanks for your input.

http://www.rollsbattery.com/pdf/2YS31P.pdf , the ultimate battery for your situation if you don't mind 280 lb batteries :o) I originally thought about this one but decided against, because of difficulty of handling and "all the eggs in one basket" situation (and length of stay in my current location). But if you can go with this big guy, then it may be what you are looking for. (ends in preposition and doesn't care one bit :o))

Otherwise, you may take a look at these 7yr ... Trojans ... the ones I have. This is where I got them with quantity discounts ... http://www.trojanbatterysales.com/t125.html

or L-RE size 8-12 years http://www.trojanbatterysales.com/l16re-b.html (I'd have gotten these, but I intend to move in the next 4 years.)

http://darklingcastle.com/ ... another guy who has good info on off-grid living and more importantly will share his experiences by reply @ http://darklingcastle.com/contact.aspx

www.off-grid.net ... Site I found most helpful in going, almost, off-grid. Home owners organization rules prohibited me from totally disconnecting. Just another example of those before you may know what's best ... it wound up 173 bucks in the hole for last year. 9 bucks a month just to be connected + some other fees per month and 83aH in the red. I would have made it to the black, if not for two hurricanes in the summer when I had my wind components tucked away. Hope that is not too off topic.

Anyway, good luck, ... if you care to chat "my profile name with only one t" at ya-hoo just one t not tt.

Why?

Lithium-Ion is the most expensive battery. The advantages are mainly energy density, size, and mass. The disadvantages are cost and the need to regulate the operating temperature.

If your desire is to power a house or building, then size and weight are not really a factor. Cost would be a factor.

Deep discharge marine batteries offer the best bang for the buck. They are a proven design, relatively low cost, and are not finicky about ambient temperature.

I seriously doubt that lithium-ion will ever match marine batteries in cost, at least not for the foreseeable future.

Then there is the other side of your question; what if EV batteries don't flood the market?

http://cr4.globalspec.com/member?u=1169 Thank you my friend for your timely responce.I too have come to the same conclusion. I think I will avoid a lot of problems just by staying with wet celled 6 volt batteries. $200.00 a peice seems like a real bargain now that I think about it. Reading Peters reply about EV batteries made me think about purchasing a Battery Management System. More money, but it will save me time and money in the long run.For those of you wondering, our electric bill sometimes goes over $700.00 per month, and we often suffer from storm outage. We have been without electric for 15 days at a time, but our bill continued like we had power all the time.That just ain`t right, and if you complain, you could end up with no power.When the sh$#@%%t hits the fan, everybody and their brother shows up here wanting to know whats going on, cause I`m the only ham operator in these parts.SO, off the grid is my goal, and they can keep their power. Thanks for your reply. Bob KC0VEA

Thank you Peter for this infomation. Buying from the UK would probably break me on the shipping charges, but their is a lot of information here. Thank you so much for your help, it was very interesting.I have a Interstate Battery dealer here locally that I am working with. I just about floored him when I brought my 8000 watts inverter in for him to size it up. Then when I went back to the car and got the step up transformer for him , he wanted to know what city I was going to power.I always do things big. I learned early big can be your best friend, and save you a ton of money and time if done big in the first place. Out here in the woods, bigger is definately better. I build my own antennas, and my own towers for my many ham radios. A lot of people have told me my place looks like a C.I.A. listening post, cause I have so many towers and antennas. It takes a conciderable amount of power to live out here.But, theres very little going on in the world that I don`t hear about. I like being informed. Thanks for all your help, Bob. KC0VEA

I wish i still had my rigs i could call you

G7LYQ thats where i goy nick name on here from

I too used to make my ariels when i had a house

Hope it all works, I wish i lived in the middle of nowhere

Peter...

I always suspected you were a ham... from your screen name.

Bill NW7L

We are hiding out all over CR4.

Many of us are. ;-)

Just bought an old TS-940 that I am waiting for delivery on.

Thank you again for this information from the Battery University Peter. What a wealth of knowledge that is. I will certainly be going back there from time to time. I have 4 tube radios that I talk on most of the time Peter. I wish you still had your rigs so we could talk. I`m storing my electronic radios in a Faraday cage until after the November elections. Some people think a ship 12 miles off our shores will send up a cheap rocket and detonate a EMP charge which in theory could wipe out our electrical grid, among other things. It won`t effect my tube radios, but it would destroy my high dollar radios , plus my inverter, and my step up transformer. After November elections I`ll drag all this stuff out and hook it all up. Take care Peter, and thanks for the good info. Bob KC0VEA

Glad to be of use.

Take Care G7LYQ out

I know all about the nickel/iron batteries, as I have been looking for them for over a year. Not new ones mind you, just any old ones I could find.They are whats known as the cats meow, or the bees knees. If I had a couple of these batteries, I would be set for many years to come. Thanks for your reply, I like hearing from people like you.Does these old batteries even say nickel/iron on them. I wouldn`t really know them if I saw them.But if they had Edison stamped any where on them I would grab them up. Again, thanks for your reply. Bob KC0VEA

Nickel Iron batteries generally require 100 watts in (production) to get 70 (65 typically) watts of charge out - less efficient than Lead-Acid (85-95%). Do the numbers & see if it may be a false economy or will meet your needs. Read this, as more cost on the production side & the storage side than Lead Acid. AGM's (98%+) might even be better - they are very close to the same benefits of NiFe ... trading efficientcy for a shorter cycle life. As Genius pointed out, there are situations where NiFe's are attractive. Your own situation, is the end all be all, to say which is the "bee's knee's". 1000 hp tractor racing nascar? or the veyron in traffic? That would be cool but impractical. Where are you located? Shipping costs may be a big variable.

Finding a few NiFe's probably won't be worth your time unless you can come up with about 20 (1.2V/cell) of them for a modest setup & it sounds like you would need 60 or more by the monthly bill you run up. Also good luck on finding any descent ones - they CAN last long but the guys I read about, that found them in train yards and old forklifts, didn't find much capacity left in them. Again, I don't know your kw/h rate so I am guess-timating on the number you would need.

Some old pic & webs sites for NiFe batteries listed in an old wind power magazine.

Another use can be coupling with Solar panels. Independent Solar panels needs battery for storage , increasing overall cost. So if battery is already there, having only Solar panels can be economical and would reduce grid power use all round the year. Inverter makers can adopt this add on to get more customers.
