    John the last bit you said about getting to 1.8 and staying there,,,, I have only done a few charges on these batteries so I still don't know them but mine seem to run up the knee really quick compared to any of my lead acid. The thing is though that once it's on the upper knee you still charge for awhile and they do bubble like crazy. The great thing is bubbling these does not deteriorate the plates, it just costs you in water maintenance. I'm going to shoot a video tonight because I have been waiting to get a run on them with work and all but what you described sounds normal and alot like what mine do too. I'll post a video a bit later of a charge run.

    Hello group,
    I have a first video of a charge cycle here on the 10 cells in series. I mostly say it all in the video but this was done in common ground at about 4A on a six coil. I think next time I may try shortening up the run a bit.

    Here is the charge chart:

    I have a discharge on the CBA running right now but it is not finished. I will post that once it does finish.

    Here is a video of this charge:

    I will comment more if anyone wants to chat about it, kind tiered so I'm just trying to get this posted. I do see these Nife cells as being very viable for daily use though. Loving them!

    Thanks for the update Bob. Looks like you're starting to get some good mileage out of those batteries.

    Interesting to note that as I charge more of my cells I'm seeing different behaviour. The first 2 cells sat at around 1.81 volts for 99% of the charge cycle, however the third cell started at around 1.45v and then slowly increased to 1.8v by the end of the charge. This cell took 1.5A for the whole 10 hour (over) charge period.

    You our are right about these cells "fizzing" away madly while charging. It's a bit un-nerving at the start, but since they do not heat up or froth over and the off-gas valves appear to be working as they should I'm a little less worried.

    It it seems the only way to kill these batteries is to let them dry out, under or overcharging or even letting them sit uncharged doesn't seem to harm them. I guess that's why they are hard to buy, even if they do cost more up front and their energy density ratio is fairly low, once you've got them, you have them for life.

    Yea that was the main attraction for me, they can be abused and last forever,, I mean what else could we want.

    I am going to go out on a limb here but I think these cells may offer some advantages when running on an SSG or that type of charge circuit. The characteristics are very different and I think they have pretty low impedance by comparison of LA. I do not remember which video but there was a youtube that Mr. Bedini did where he was talking about some Alum conversion batteries he was working with and he started to make some comments,, something like "it was the batteries all along" he was sort of excited and the impression I got from it was that there was something special going on with the alkaline base verses the acid base. Granted he was using the alum on lead plates but I think those converted batteries behave closer to these NiFe cells than their original behavior as LA.

    We shall see how they do over time. I plan to run many more tests including running in mode 1 and some cap dumping as well. I think I could have shortened this run I just posted but that is something I also need to test, bring it up to the upper knee and not run it so long to see what I get back out. It's going to take time to figure out the right way to work with these batteries but as I figure stuff out I will continue to post some examples in this thread.

    Here is the discharge chart from that run. It did very well in my opinion. I notice that it was still strong when it got to the 10.5v that I set the cut off for. In other words there was no drop off. I think at the half amp rate I could have maybe gone down to 10v or even 9. The other way to look at it could be that I can probably pull .75A or 1A from them,, more testing is needed.

    That last run did go well Bob. Looks like it would've got to the 10Ah rated capacity, so you must be doing something right

    I'm charging the last of my 5 cells with an overcharge now. Should be able to get a baseline discharge curve for each cell tonight.

    Hi BobZilla --

    I have been contacting the battery company in China that makes these Nickel Iron batteries to get pricing and delivery
    by sea. Since I am near to the Baltimore Port of entry the travel to pick them up at customs is not more then a 30 minute
    drive. The sea transport cost from China is $100.00 US dollars and the weight is like 250 pounds for 20 of the TN-100 Nickel-Iron batteries. The cost of each battery is $45.00 dollars. The terms for paying for them is 30% of the order total up front to start the battery order and then 70% once the order is ready to ship. These are direct bank transfers of money direct to their account. The cost of each transfer will be at least $30.00 dollars more due to it will be two bank transfers. Then starts the sea transport of 25 to 30 days. By the time you get your batteries 45 days would have passed by. They complained a little in the email of not getting a 100 battery order but said they would proceed with the order and called it a sample order. I am still working on this with the customs people to make sure they are not held up at the Baltimore Port for lacking paper work to get them into the country. I am also researching the import costs if any. Its very hard to communicate a quote to them. They think its an order. I did get the price on the TN-10 batteries also and they want $5.80 per battery. The price on the TN-50 was $23.00 dollars each and the price for the TN-200 with $89.00 dollars each. I am still working on if the connectors and the filler is included. It has been an ordeal as there English skills are not very good for understanding what you write to them. They did send me an operators manual on the battery in Micro-Soft Word format but its to big to attach to the forum post. If you want a copy of it just PM me with your email address.

    Hi James,
    I just PM'd you. Thanks for the offer.

    So I'm curious all said and done how much would you be saving by going this route instead of ordering from say Iron Edison here in the US or even IronCore? I did come across links in places like Alibaba when I was looking but then I realized all of the hassle you described with customs and communicating the order etc.. I just didn't feel comfortable trying to pull it off myself. I paid a lot in shipping but I did not have to worry about anything going wrong and it was delivered right to my door.

    Eventually I do want to get some large cells and I will have to consider options for getting those.

    Hi BobZilla --

    I sent you the battery document file. If I were to order 50 of the TN-10 batteries they would cost $5.80 each
    plus $100.00 dollars to ship via sea freight. The up in the air part is the customs fee which could be free for an order
    under $400.00 dollars but this will be more then $400.00 for the type of battery I want. I am still researching the
    custom fees. So the direct price would be $290.00 for the 50 TN-10 batteries then $100.00 dollar sea freight and it
    may be no custom fee. But there will be bank fees of $30.00 to $40.00 dollars. So the total will be $430.00 for 50
    TN-10 batteries buying direct from the factory in China. The cost per battery would be $8.60 total with all the other
    fees already included. You said you paid $15.00 per battery then paid a shipping fee of which you never said what
    that was.

    I don't remember exactly how it broke down but it was $1081 all said and done. That did include a international bank transfer fee also. So yea you could save some serious money. I guess you would be picking them up yourself at the Baltimore port? I was watching the tracking on mine and they came to the states in through New York so just be sure you know where your stuff is going, that would suck if you had to go up there to get them.

    I know I paid a lot for these things but what can I say, I am glad I have them. Like I said starting out I could have had the 100AH from Iron Edison for roughly the same but then I would not have as much versatility with voltage or splitting them out into two banks.
