" Once I had a proper battery pack charger, on the way, I was confident enough to tak 'er "out" for a spin (just, around a few blocks & only discharged the battery pack down to ~43V)

All I can say is, Oooh, Baby ...just, Oooh, Baby

Here is the video of my first ride with the Volt lithium battery

& here is the video of my second ride. (same day)
I had my daughter Desteny record this ride for me, to get it from a different perspective.

" That is the title of the feature article, which starts on page 76, in the June 2011 issue of Popular Science magazine. It is written by Seth Fletcher, and contains topics from his new book titled: Bottled Lightning: Superbatteries, Electric Cars, and the New Lithium Economy.

The article discusses the current availability of the various 29 elements "from the far corners of the periodic table" that are now in great demand due to the advent of green energy and electric vehicles. He debunks some naysayers who claim that we will soon run out of some of these elements, such as lithium, cobalt, tellurium, neodymium and the like and discusses the would-wide availability of these elements and what is needed to find more and to extract them from the earth.

If you would like to get some sort of feel for the types of elements and minerals required to keep our solar power, battery technology and electric motor manufacturing businesses in operation, you might be interested in this article, or maybe Mr. Fletcher's book, which is published by Hill & Wang and came out on May 10.

" Now that she's all ready to go & we have meters (to monitor "the battery") next was to search for a "proper" charger

Remember, this 2kWh section of a Volt battery is 45V nominal/average (NOT 48V) & the "safe" usable voltage range is 3.3V per cell (39.6V) to 4.1V per cell (49.2V) so, a standard 48V battery charger with either a 50.4V or 54.6V (top charge setting) will not do

Looking for a "smart" charger that can be preset to a 49V top charge was an "uphill battle".
I sent messages to Shauer (here in Ohio) & many, many others, most said that they couldn't help me (?REALLY don't you'all make/design/build battery chargers?) & others said they just "sell" premade units.

I finally found a few that said they could get preset chargers, like an ElCon 1,500 ($569.00+ shipping) @ EVwest
(but they were "ridiculously" expensive, even more than the battery itself)
http://www.evwest.com/catalog/produc...roducts_id=247

I found the same charger @ EVAssemble ($340.00 + shipping)
http://www.evassemble.com/index.php?...products_id=17
then, Michael @ EVAssemble messaged me back & told me about a "new" ElCon 1,800 ($225.00 + shipping)
http://evcomponents.com/elcon-tc-hk-...w-charger.html

I messaged him back "I want one". He asked about some battery pack details, but then I never heard back (ever)

Still looking, I found the same ElCon 1,800 for the same ($225.00 + shipping) @ EVComponents
http://evcomponents.com/customized-c...w-charger.html
so, I sent them a message, "I want one". The same "Michael" guy answered & asked the same questions
I gave him the same answers & haven't heard back from him (same guy) either

Later, I found this 15A Chevy Volt 12S Li-ion charger ($300.00 delivered)
https://www.ebay.com/itm/223038081042?ul_noapp=true
In the specifications it says: "Voltage can be lowered to a lower number if you do not wish to charge your battery full"
I said to myself,yes that's what were looking for, but I was concerned about the 15A charging rate because while doing battery charging research, on solar forums, I remember reading that for normal charging they recommend a charge rate of ~20% of the battery packs AH (capacity rating) so, for this ~50AH battery pack, a 10% charge rate would be 5A (very slow or maintenance charge), a 20% charge rate would be 10A (slow charge) & a 30% charge rate would be 15A (faster charge)

Then, I found Yewi, a "Chinese" co. that would make chargers "to order", for like 1/2 price (I hate the way the places that sell EV stuff mark stuff up SO much) & they get their chargers from China too.
So, I ordered a couple of their Yewi UY-600 (48V 10A) lithium battery chargers, to save a few bucks & for a slower "proper" charge rate (to hopefully help this battery pack last a long, long time)...we'll see how it goes "

" That is really interesting, Ted. I love stories that have connections like that. In many cases, when you dig down into a story, you run into interesting connections illustrating that it is really a small world - especially when it comes to the development of the electric motorcycle.

And since you mentioned KTM and the FreeRide E, I don't know about elsewhere, but here in California there is not exactly a big rush to buy that dual-sport electric motorcycle. The local KTM dealers don't seem to have any interest in selling the model. I guess I can understand that reluctance as this is a big place and the FreeRide E is not really up to traveling any distance on paved roads and in my area dirt roads are all privately or publicly owned and their use is restricted to hikers, bicyclists and hay-burners. Powered vehicles prohibited, even when they are bicycles that have an electric motor assist. "

" Wrapping it up for the weekend - (breaks added for clarity)

Here’s where the story of Schless and his Blade gets interesting.
Schless was deeply connected, and because of these connections was able to
establish placement of his bikes in some fairly diverse worldwide markets.

He had the bikes in a Scott Valley CA bike shop for a few months, a local
haunt of Zero founder Neal Saiki, shortly before Saiki built the first
Electricross Drift.

Allensandro Tiburon was the Blade European distributor,
and the cousin of one of Quantya’s founders: Claudio Dick. Dick,
apparently with the help of Tiburon and Max Modina, from Cagiva, put
together the first Quantya with very slight modification of the Blade design.

Schless had a building in Ashland, OR he was renting to a small car
fabrication start-up, and his former Denali frame designer, Brett Gober,
commuted to the place on his Blade. Apparently the start-up’s owner was
interested in the bike, and thought he could do better. The owner? Craig
Bramscher, and the company: Brammo.

One more. The Blade Austrian distributor, Georg Dernforffer, had a
roommate. The roommate worked for KTM, in Austria. Apparently
“…they (the roommate) took his Blade and played with it.” Years later, in
2014, KTM launched the FreeRide E, becoming the first established gasoline
motorcycle company to offer an electric powered bike, and a motocross bike
at that.

It’s obviously a stretch at best to claim the Denali and Blade had
confirmed, direct influence on the start and development of these four
companies with such circumstantial evidence. However, the fact that the
Denali had been in production for several years, and the Blade was in full
production for 4 years prior to the launch of Zero (2006), Brammo (2008),
Quantya (2005) and the FreeRide E (2014), amounting to nearly a decade of
successful production, performance and sales, it’s simply not reasonable to
assume it had no impact at all.

Schless undeniably set the stage for what would become a new paradigm
for two-wheeled motorsports.

Attachment 7973

Lest you fear Ely Schless has withdrawn from the electric motorcycle
world, fear not. The photo above comes with this message: “I built this
frame for Victory Brammo this past year for the Isle of Man where we
finished second behind the Honda Mugen bike (119 versus 117 mph
average).”

See why I had to go back to the drawing board? Have a great weekend! "

It certainly does.

Another subject that has been on my mind lately is what are the proposed tariffs on just about everything imported from China into the U.S. going to do to electric motor parts, batteries, controllers and the occasional California electric motorcycle company prices? My guess is nothing good. Electric motorcycles and their parts are already too expensive for most of the general market to bear right now. Jacking up prices by 10%, or likely 25% (since the Chinese are not likely to want to "loose face" by caving into "our" demands any time soon) is really going to depress the electric motorcycle market - and likely related markets, too.
