Converting from Lipo to Silver-Oxide

[Meniscus]

So, who is converting from Lipo to Silver-Oxide?

No concern about fire

They seem to have some great possibilities. It is stated that they have 40% more capacity capability than lithium ion, without the risk of flamability.

It will be interesting to see how Zpower will market them. I can't but wonder if they will be able to deliver the high amp draw that FE requires.

Let's say it is on the way. The military has been using for a few years now for various.......things.

Let me see what I can do about some links. Remember, you heard it from Meniscus first LMAO!

Hold the horses, cowboy! I'm still struggling with the Nimh to Lipo conversion...

I'm still struggling with the Nimh to Lipo conversion...

Well, you could skip Lipos and go straight to Silver-Oxide

[Eodman]

Oh hell just when Lipos were coming down in price a new freakin technology comes along!

Attention thread viewers:

Remember that you heard it from Meniscus first. So, when you make your purchase of Silver-Oxide batteries, just go ahead and double the order. Then send to me!!!

LMAO, J/K

I'm still working on a list of links of what I can find.

It would be interesting to see some comparative figures. Compared to NiMh and LiPo regarding discharge rates, configurations, weight and COST. Please keep a look-out for them in the RC forums!

As Egneg has already mentioned: ZPower

More info to come today as soon as I get a response from one of the vendors I work with supporting the military.

Some Specs of small format, but still applicable

Silver Oxide Batteries

Silver Oxide is the nickname for a silver oxide-alkaline-zinc primary battery. And it's nicely priced for the dependability and power it delivers. The image to the left is a typical Silver Oxide round battery. Additional information and a more detailed cutaway view are available by clicking on the image.
Two types of Silver Oxide batteries are available, one type with a sodium hydroxide (NaOH) electrolyte and the other with a potassium hydroxide (KOH) electrolyte. Sodium hydroxide types last two to three years making them highly suitable for quartz analog digital watches or digital watches without backlights. Potassium hydroxide types are better for the short bursts of higher current drains that are required from LCD watches with backlights. Hearing aids and electronic measuring instruments also use batteries with a potassium hydroxide electrolyte in combination with a special separator to match the application.
The Silver Oxide battery has a higher closed circuit voltage than a Mercuric Oxide battery and a flatter discharge curve than the Alkaline Manganese Dioxide battery.
The current delivery capabilities of a Silver Oxide cell are determined by the type of electrolyte used, as shown in the chart at the left. Like the Mercuric Oxide cell, when the potassium electrolyte is used, the cell offers less resistance to current flow. This allows the cell to operate at a higher efficiency under heavier current drains. At low current drains, both the sodium hydroxide (NaOH) and potassium hydroxide (KOH) electrolyte operate with the same efficiency.
The open circuit voltage is 1.6 volts. With current drain it is typically 1.5 volts or more. Silver Oxide cells exhibit a very flat operating voltage discharge curve that has a higher voltage than Mercuric Oxide cells. The chart to the right illustrates this comparison.
Silver Oxide Battery Characteristics

• Type Primary Chemical Reaction Zn + Ag2O KOH --> ZnO + 2Ag or Zn + Ag2O NaOH --> ZnO + 2Ag
• Operating Temperature 32º F to 130º F (0º C to 54.4º C) with KOH electrolyte. NaOH electrolyte operates less well at low temperatures.
• Initial Voltage 1.45 volts
• Capacity Varies
• Discharge Rate Flat
• Internal Resistance Low internal resistance. KOH electrolyte is lower than with NaOH electrolyte. Impedance Very low.
• Storage Life Loses less than 10% after 5 years.
• Storage Temperature -40º F to 150º F ( -40º to 60º C)
• Disposal Not recyclable; check with your local authority (city/county/parish) for proper disposal.

Ben, this is assuming we are using LED's and watches or is it at high amp discharge as well?
It seems to me that these are supposed to be used in our Tx/Rx since they mention watches...I don't think this will replace the power of lipos for now at least... or do you have bigger amps samples to show us?
