Re: Trojan Reliant AGM Battery Reply #25 – March 30, 2015, 03:28:29 pm Yahoo Message Number: 151968"The lithium polymer batteries used in R/C models such as your mini-monster truck are different from the lithium-ion batteries we're talking about for RV use."Thank you for pointing this out. One reason love this group is I am constantly learning from the technical experts here.Maybe TESLA will revolutionize battery technology at the multi billion dollar plant they are building in Nevada. They have special charging stations in Las Vegas. Sure would be nice to pull up and recharge "free of charge".bobmoore14
Small lithium batteies used in Tesla with link to PDF was --> Re: [L Reply #26 – March 30, 2015, 03:40:36 pm Yahoo Message Number: 151969This is about small batteries not large battery packs that are available for RVs.Do you know that Tesla uses 18650 batteries? These are 18 mm dia by 650 mm length. Shaped and a little bigger than a AA battery (I believe AA batteries were used to power the fastest electric car).One thing that hurts the lithium market is there are a lot of cheap bad quality batteries on the market, especially from ebay and Amazon. Tesla uses Panasonic brand. Recently there was a news story of a vapor cigarette machine catching on fire. The reporter did not say what kind of battery other than it was lithium but my guess it was a cheap ebay battery.On Youtube there are a lot of people opening up laptop battery packs and taking out the 18650s and using them for electric bikes. And some of them get amazing ranges. Search on "18650 battery".I have not come across anyone taking real Panasonics and building safe packs like Tesla (because of the costs) with cooling and fire foam. And Tesla batteries are safe.But according to the linked PDF, the 18650 compares in price with high density packs (surprise). Also in the PDF are what other car companies use (no other company uses cylindrical cell batteries).BTW 18650s are used in almost all laptop battery packs and in lithium battery packs for power tools. There is a 28650 but because it is not used as much as the 18650 the price per watt does not work out because of production.Some 18650s come with an electronic circuit at the top of the battery that adds a mm to the length.One thing must be said about Tesla and that is Panasonic is a part owner and Panasonic makes their batteries. But Tesla is the worlds leader in batteries.I would like to come across a commercial battery pack that uses 18650s and allow the user to test and replace bad batteries, that are for RVs or solar home use.I think the moral of this story is well designed batteries do not catch on fire and cheap ones do. And on top of good cells, you need good electronics and fire suppression systems.This PDF is 39 pages. The first photo shows the 18650 tops in a plastic see through case. The real case is black. This PDF is an extract of the full report which costs money (I assume a lot). Details in the cooling is blacked out but there is one diagram showing the flow path of the coolant. It goes down every other row of batteries. My guess is no one can figure out how to do this cooling.Heavy reading but some interesting photos and facts. One is that Tesla may go to a larger cell like a 20700 (I never heard of this size)http://advancedautobat.com/industry-reports/2014-Tesla-report/Extract-from-the-Tesla-battery-report.pdfAmazon link to Panasonic 18650http://www.amazon.com/s/ref=nb_sb_ss_i_1_15?url=search-alias%3Daps&field-keywords=panasonic+18650+battery&sprefix=panasonic+18650%2Caps%2C308I believe Technomadia (they use the big packs) talks about heat in:https://www.youtube.com/watch?v=-m6aCNzHkwsSo if anyone comes across someone using 18650s for RVs let me know. My gut feeling is Tesla is not wrong.One last comment - I believe the large lithium battery packs for RV cannot dissipate the heat well and thus reduce the life of the battery. If someone is thinking about large packs, I think they should look into this.FYI H bombs use lithium, the same element as the battery !! It just takes a A bomb to set them off (also an H can set off another H). I just wonder if a A bomb goes off, would it set off all the cell phones ??? ie a world wide chain reaction ?? ummm going to Google this now ha haSan Diego Roger As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.

Re: Trojan Reliant AGM Battery Reply #31 – March 30, 2015, 05:57:33 pm Yahoo Message Number: 151976Joan, here it is. It comes as a complete kit. Battery (1 x 3 x 9 inches approximately), carrying case, cables to connect it to your LD battery, chargers to charge it, and small adapters to use it to charge your cell phone, or laptop or whatever. They say it outputs about 600 Amps peak, and I believe it.

It could be an evil website, i.e. one that will attack your machine looking for a vulnerability.Also, given that the link goes via the tinyURL website, they can track you. They know who you are and where you're going and will remember it. That's why it's free.Other than that, tinyURL is convenient.Alex Rutchka, SE #4 '05 MB

It is good for 20 miles of riding in hilly New Mexico when I assist with pedaling, which I always do. Battery retails for $750 and allegedly is good for 1000 recharges. Entire bike with battery retails for $2900. After decades of riding conventional bikes in Flat Florida and Long island we moved to Steep Santa Fe and at age 86 I can keep on riding.

Re: Trojan Reliant AGM Battery Reply #36 – March 30, 2015, 06:35:57 pm Yahoo Message Number: 151982"That is a very neat, multi-purpose tool!"Indeed. And I can verify that it will start a Lazy Daze's Ford V10 engine multiple times on a single charge... as well as recharging cell phones, tablets, wireless hotspots, and anything else that can be powered from a USB port.It also comes with a variety of adapter cables that allow charging many laptop computers. (Unfortunately, a cable with Apple's MagSafe charging connector is not included.)The Antigravity battery pack is still more useful if you add an accessory 12 V outlet, so that it can power any 12 V plug-in device (up to 8 amps).Andy Baird

Heck, I regularly see 'em in truckstops at the counter."How many amps does an iPad Mini 3 draw?"A maximum of 2 amps at 5.5 volts, the standard USB charging voltage. Actually, it will rarely draw that much unless its battery is really, really low, but you want a charger that has the capability.When buying a charger for an iPad, look for labeling that says either 2 amps or 10 watts. Older chargers that put out 1 amp/5 W will charge a phone just fine, but will barely trickle-charge an iPad.Andy Baird
