Silicone Batteries
I know thing have been bad for silicone batteries. I hope maybe they will change as the lawsuit over the patent has now been resolved.
I have signed up to sell the silicone batteries in the USA and my first delivery of batteries will arrive at the dock in Long Beach on 7-9-07.
The batteries will go into a force electric car and an off grid house. I will be selling these batteries to at cost to anybody that wants to help me test them out.
My site is www.siliconebatteriesusa.com
Welcome aboard!
As long as you are here, how about a few more details such as the battery specs, dimensions, where you get them from, expected life span and so forth. Oh, and what is "cost?" Are these the same batteries that are sold into scooters like the EMax?
I think you'll find the folks in the forum reasonably friendly and open-minded, but the collective experience with silicone batteries so far has been a bit mixed. Most of us EMax owners, including me, have already worn out the original silicone batteries and have replaced them with lead-acid. In every case I know of the lead-acid replacements out-performed the original batteries.
I have also always wondered about the environmental claims of silicone batteries. They still have lead plates in them right? So even if the silicone electrolyte is benign, you would still have to do something about the lead before disposing of the battery. Presumably the electrolyte would also contain a fair amount of lead at end of life and would also represent a disposal problem.
As I read back over what I have written it sounds way more negative than what I intended. I think your presence here might go a long way toward answering the questions us silicone battery owners have built up over the last couple of years. I'm sure there is a spot for silicone in the pantheon of batteries used by our ilk. Anyway, welcome.

The silicone batteries in the e-max were made by "Guineng" which I understand was accused of infringing on the patent holder, "Greensaver". Is this correct? Any info. on the settlement?
I am open to the possibility that the the Guineng batteries were made under poor QC and our experience with their poor performance may not be refective of the actual performance potential. But it can't be much better or it would still be noticable above the inconsistent quality "noise".
The only noticable difference is that they do seem to maintain their capacity in cold temperatures better than regular SLA's.
The best way to remove our skepticism would be for you to simply publish discharge and cycle-life curves for the silicones from an independent lab.

I am interested in running test on those batteries , want to know A/H , size , voltage , internal impedance , price ,
can they be obtain as single cell ( 2 volts) in what A/H .
Have over 40 years working with all chemistries type cells.
I can be reached at (203)627-8426 .

I have ordered 58 silicone batteries from greensaver batteries of China. Greensaver is now the only maker of the silicone batteries in China.
I have ordered twenty four ssw230-6 batteries,eight sp210-12, eight sp20-12,fourteen sp100-12,one ssw120-12, and three sp10-12.
The web sight to decode those batteries codes is the greensaver sight www.greensaver.cn/en-about.asp
The cost of the batteries is about the same as lead acid to about 20% more.
It was very hard to get this order I tried for about a month and had to meet some condition before they would take my order. I think they have enough domestic business that they don't need any other business. It took about 4 months just to get the batteries but they promised it would only be 45 day on the next order. As far as I know I am the only importer of the batteries in the usa.

Great news, but still a lot of unanswered questions.
Exact cost without shipping?
Refund Policy?
There still is very little information on your site, I just assume from your area code your in CA.

I will be selling these batteries to at cost to anybody that wants to help me test them out.
What happens next after the test?

A person who has a blog or would report to this sight all results and experiences they have with these batteries would be a person I would sell the batteries at cost. This would be about 30% less than retail. Batteries for an emax would retail for $49. The factory has a one year warranty
on the batteries. I am in the Fresno area of California.

`Eric,
What your proposing sounds great, but I know we'll have to setup some criteria on how it's presented. Even before that happens I need to run it by others.
We'll contact you off site for some additional details.

Sorry I have not written but have been busy with my silicone battery business and testing the new silicone batteries.
I have an electric car that I have been testing you can read about the testing and see pictures of the silicone batteries installed in the car by going to http://autos.groups.yahoo.com/group/solectria_ev/ I am also testing the batteries in my off grid home. They have worked well, they work about the same as lead acid batteries except they are easer to charge with the voltage rising only a little during charge how ever when the are done charging it will rise quickly. I have found that absorption charge is not hardly needed I set mine to one hour, normal would be 2 hours. With the low resistance of these batteries I think it could be easy to over charger them which could lower there life span. I have updated my web site at www.siliconebatteriesusa.com with type and sizes of batteries and some prices.
Eric Fisher
I read your technical specification off " siliconebatteriesusa.com ". somewhat confused by the internal resistance number listed ,------ > 0.5 micro Ohm and < 0.25 micro Ohm ---------are those figures for a cell ? ,a pack of cells? and what Amp/Hour rating ? .
Can you please clarify , I am very interested in internal impedance , since this is the figure that fixe efficiency in charge and discharge cycle with in turn create HEAT = "BATTERY KILLER "
Thank you
Currently I am personally testing the operation of silicone batteries in three different places.
I have an electric car that is a 1996 Force electric car, with 13 sp100 silicone batteries. I have driven the car 2,000 miles so far and have had no problem with the batteries. They are rated a 100 amp. hour at a 5 hour rate but in my testing they have performing at 120 amp. hour at a 2 hour rate.
I also have an off grid house with 24 ssw230 silicone batteries, they have preformed very will so far now running for 5 months. They have shown to be quit efficient. On my meter that shows percent of charge, you are to select the efficiency of you batteries I choose 100% for the silicone batteries and this has been the good setting showing the correct value so for. My lead acid batteries worked at a 95% setting.
I also have a Sunbird electric scooter power by 3 sp12 silicone batteries, so far they are working well. I use it every day on the flight ramp at work. The scooter had lead acid batteries in it originally.
If you have any questions about silicone batteries feel free to go to my site at www.siliconebatteriesusa.com and contact me on my email there or write to this forum. I have been working at my normal job as a seasonal fire fighter for the forest service but I will be laid of for the season next week and will have more time to spend with my silicone battery business.

The Summer Season is coming and some of you are using chargers that are not temperature compensated.
Please be aware of the max. voltage for charging 12 volt Silicone Batteries during the warm Summer temperatures.

Fisher ,could you push on Greensaver to develop bank charger ? Tracy and me both push on them a lot...
I now have about a year and a half working with with Silicone Batteries from Greensaver. I have sold over 250 batteries in that time. I have not had any problems with the batteries except Fedex has dropped some batteries and I had to replace them. I have an electric car which has 13, 12volt Silicone batteries. I now have 6,500 mile on the car since I installed the Greensaver batteries. They have performed very well. You can read about the car at this link.

I also have an off grid house with 48, 6 volt Greensaver batteries which have run with no problems
I have an electric scooter that I run all summer at the Fresno Air Terminal in California. I only charge the batteries at night in the early morning on a timer because it does not have temperature compensation on the charger, my car and off grid house has this feature on their chargers. I found out by testing the scooter's charger that in the hot summer weather, if you were to charge the batteries, you would exceed the voltage limit for the batteries. The limits for charging silicone batteries can be found at my site at the technology page.
I believe that most of the problems with early silicone batteries could have been caused by exceeding the voltage limitations of the batteries by using the chargers which came with the scooters and have no temperature compensation. I have not heard of any China scooters with the temperature compensation feature.
I have had some price increases from Greensaver in the last year on the batteries. I have been told they would give me some better prices on my next order as the price of lead has dropped. Also Greensaver would not take US dollars and required payments in euros.
I have very little stock at this time but I do have a matched set of batteries for an XM-2000.
I am no longer considering selling lithium battery at my site considering all the problem they have and the need to ship them as hazardous material.

I was looking for reviews on these batteries and was surprised to find nothing very current? It seems like no one is using them? I have (6) 12 volt,35 ah batterys in my motorcycle conversion and was looking to try the either the GS SP38 AH or BB 35 AH in the spring. Can you direct me to any user reviews on the Green Savers? Thanks Phil
Phil, I did sell a set of 14 Greensaver SP36-12 batteries to the owner of an Sparrow Electric car about 6 months ago. I will email him and ask if I can give out his email.

Hello Eric,
When are you getting your next shippment? I am interested in the U1 size. Anyone using in a motorcycle?
Phil
Phil
I am going to be making an order of GreenSaver Silicone Batteries in about a week.
I don't know anybody that is using the Silicone Batteries in a Motorcycle just Scooters.
The SP27 Greensaver battery is the U1 size. I should be able to get you some in about 45 days. I will get you a real good price. The price of lead has dropped and Greensaver says I will be getting a good price break on my next order. If you only need 5 I have a matched set in stock of that battery I have another one but it is one lot number different. I was surprise it was different because they come in boxes of 2 each and one of the boxes of 2 had two different lot numbers.

Eric, a couple months would be fine. Will soon be too cold (for me) to ride in NJ and my sla's still have life in them. I will need 6.
Phil
Mal, very impressive build! You boys down under sure aren't shy on the volts! My bike is only 80 volts and I had it bite me once or twice during the build. At 600v once would be all you would get! I like the battery balance with zener diodes, going to give it a try. Be interested to see how the GS batterys hold up too. When do you expect to be in motion?
Phil
I will make sure I have Greensaver send me a matched set of six SP27s on the next order. I will also be ordering some SP27s for the XM-2000 Scooters.

I have a damaged battery that was dropped by Fedex during delivery. Some of the people on this site were interested in taking apart a Silicone Battery to see what it is make of. I am offering this battery to an one who wants it. It is a SP68 battery for an electric car. I will send it to anybody for just the freight cost.

I bought 3 Greensaver batteries f/ Eric on Ebay in Feb '09. So for so good. It's a 36 v 12 ah pack with higher discharge capabilites. It's like I'm riding with a 14 or 16 ah SLA pack.
On the negative side, the pack weighs 30lbs. I wouldn't say it is better than my LiFePo4 pack on an ebike, but silicone batts have much more promise in cars. The heavier weight of the batts is possibly better for downhill regen and
it's regen tolerant.
I have just gone ahead and purchased 8 of the 6v 210 batteries for my fathers ZX40 NEV. Should be interesting to see how they perform in the winter.
They should be much better than a set of junkyard agm telephone batteris :)
Cheers
Ryan
Can you post pricing info?
