Default Mastervolt is a Leader in Lithium-ION 12 and 24 Volt Battery Technology for RV Marine

Just doing a little more research on batteries since it is a hot-topic button and thinking back to the post where Sean (NewellCrazy) shared the information about the latest Lithium-ion (LiFePO4) or LFP technology and how great the advantages of these batteries would be in our luxury coaches. I would have to believe that Newell Coach will be jumping on this bandwagon relatively soon since a competitor and friend over at Liberty Coach is enjoying the success of them. Thanks to our member "jack14r" for originally sharing this.

There have been a couple of US companies that were pushing this battery technology that were financed by our recent government prosperity investment that have sort of went out of business, I've heard the company was bought out for a song by another company whom plans on moving forward with the venture. The pricing is already dropping on these batteries and will continue just like plasma or led TV's. So, they will probably be in most our reaches in relatively short order.

I'm waiting to here from someone whom has taking the plunge on this upgrade. Just check out the specification in this pdf.

Hopefully these are not the same batteries being used in 787 Dreamliners!

I have a brother in the yacht business and he has told me that the Mastervolt lithion-Ion batteries are a very good product. I had asked the same thing in reference to the 787 issue and he told me they are not the same brand or exact same technology. He also told me he has never heard of a fire starting with a Mastervolt battery in a marine application.

I think I'll wait, I've had some lithium ION batteries that went bad in way less than 5 years. Had one in a camera that 'bulged' and I had to use pliers to remove it. Had another in my XM unit that did the same thing.

Lithium iron phosphate battery


The lithium iron phosphate (LiFePO[SUB]4[/SUB]) battery, also called LFP battery (with "LFP" standing for "lithium ferrophosphate"), is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO[SUB]4[/SUB] as a cathode material. LiFePO[SUB]4[/SUB] batteries have somewhat lower energy density than the more common LiCoO[SUB]2[/SUB] design found in consumer electronics, but offers longer lifetimes, better power density (the rate that energy can be drawn from them) and are inherently safer. LiFePO[SUB]4[/SUB] is finding a number of roles in vehicle use and backup power.

Most lithium-ion batteries (Li-ion) used in consumer electronics products use lithium cobalt oxide cathodes (LiCoO[SUB]2[/SUB]). Other varieties of lithium-ion batteries include lithium manganese oxide (LiMn[SUB]2[/SUB]O[SUB]4[/SUB]) and lithium nickel oxide (LiNiO[SUB]2[/SUB]). The batteries are named after the material used for their cathodes; the anodes are generally made of carbon and a variety of electrolytes are used.[SUP][citation needed][/SUP]

The LiFePO[SUB]4[/SUB] battery uses a lithium-ion-derived chemistry and shares many advantages and disadvantages with other Lithium-ion battery chemistries. However, there are significant differences.

LFP chemistry offers a longer cycle life than other lithium-ion approaches.[SUP][6][/SUP]

The use of phosphates avoids cobalt's cost and environmental concerns, particularly concerns about cobalt entering the environment through improper disposal.[SUP][6][/SUP]
LiFePO[SUB]4[/SUB] has higher current or peak-power ratings than LiCoO[SUB]2[/SUB].[SUP][7][/SUP]

The energy density (energy/volume) of a new LFP battery is some 14% lower than that of a new LiCoO[SUB]2[/SUB] battery.[SUP][8][/SUP] Also, many brands of LFPs have a lower discharge rate than lead-acid or LiCoO[SUB]2[/SUB]. Since discharge rate is a percentage of battery capacity a higher rate can be achieved by using a larger battery (more ampère-hours).

LiFePO[SUB]4[/SUB] cells experience a slower rate of capacity loss (aka greater calendar-life) than lithium-ion battery chemistries such as LiCoO[SUB]2[/SUB] cobalt or LiMn[SUB]2[/SUB]O[SUB]4[/SUB] manganese spinel lithium-ion polymer batteries or lithium-ion batteries.[SUP][9][/SUP][SUP][10][/SUP] After one year on the shelf, a LiFePO[SUB]4[/SUB] cell typically has approximately the same energy density as a LiCoO[SUB]2[/SUB] Li-ion cell, because of LFP's slower decline of energy density. Thereafter, LiFePO[SUB]4[/SUB] likely has a higher density.

Safety

One important advantage over other lithium-ion chemistries is thermal and chemical stability, which improves battery safety.[SUP][6][/SUP] LiFePO[SUB]4[/SUB] is an intrinsically safer cathode material than LiCoO[SUB]2[/SUB] and manganese spinel. The Fe-P-O bond is stronger than the Co-O bond, so that when abused, (short-circuited, overheated, etc.) the oxygen atoms are much harder to remove. This stabilization of the redox energies also helps fast ion migration.[SUP][citation needed][/SUP]

As lithium migrates out of the cathode in a LiCoO[SUB]2[/SUB] cell, the CoO[SUB]2[/SUB] undergoes non-linear expansion that affects the structural integrity of the cell. The fully lithiated and unlithiated states of LiFePO[SUB]4[/SUB] are structurally similar which means that LiFePO[SUB]4[/SUB] cells are more structurally stable than LiCoO[SUB]2[/SUB] cells.[SUP][citation needed][/SUP]

No lithium remains in the cathode of a fully charged LiFePO[SUB]4[/SUB] cell—in a LiCoO[SUB]2[/SUB] cell, approximately 50% remains in the cathode. LiFePO[SUB]4[/SUB] is highly resilient during oxygen loss, which typically results in an exothermic reaction in other lithium cells.[SUP][4][/SUP]

As a result, lithium iron phosphate cells are much harder to ignite in the event of mishandling especially during charge, although any battery, once fully charged, can only dissipate overcharge energy as heat. Therefore failure of the battery through misuse is still possible. It is commonly accepted that LiFePO4 battery does not decompose at high temperatures.[SUP][6][/SUP] The difference between LFP and the LiPo battery cells commonly used in the aeromodeling hobby is particularly notable.[SUP][citation needed][/SUP]

Sounds like we are talking about two different animals here with regards to these lithium ion battery's. The information above sounds as if its a real safe technology. Has there been an improvement or whats missing here. I wondered the same thing ccjohonson stated.

29 different types of Lithium ION batteries, who'd a thunk?

The media does not tell the whole story and is screwing things up as usual and I don't care who they are whether it's CNN, MSNBC, USATODAY-- they are just not telling the people what they need to know--that the batteries in the Boeing are NOT the same as the batteries powering EV's, starting different vehicle systems i.e. and that there are numerous types of LiON batteries in use just like MrE posted pointed out above.

There was a time that the Tesla used this same risky Cobalt Oxide (CoO2 cells) chemistry but when they stopped production of the Tesla Roadster they changed to a more safe manganese spinel (LiMn2O4) cathodes.

This is all spelled out in detail in this article which gives the scientific facts that the media and other powers to be are avoiding informing the public:

Boeing 787 Batteries Same As Those In Electric Cars? Umm, No | Popular Science

Failure to point this out is like saying that ALL internal combustion engine technologies--such as gasoline, diesel, steam, etc are the same thing just because they burn fuel to propel a vehicle.

Obviously the media are NOT scientists and haven't a clue when they write or broadcast about these things which then ends up propelling MYTHS about realities. Shame on the media.

I would like to clear the air on the original poster here and say these Mastervolt Batteries - Are a superb product! I look forward to them becoming competitive while staying very safe.

Dang, you guys have really busy expanding on this post. I figured I would get beat to hell on it.

I was worried knowing about the problem with Boeing might ignite some controversy that would have to be cleaned up and glad I don't have to worry about it now that others have jumped on the bandwagon and sorted it out. I can see this Boeing thing possibly screwing up some advancement in the Lithium-ion market. I agree with Billy about the stupid media and I guess that why I prefer a little more of the alternative media outlets vs. the corporate controlled $hit.
