Not bad this little Reva In the style of microcars there is also the Tango: http://www.commutercars.com/ With crazy characteristics: 0 to 100km / h in 4s, max speed of 200km / h Autonomy: 64 - 96 km And all this with lead-acid batteries: shock: With the li-ion option, the range is extended ...

Ah, and I forgot the last words "do not try to recharge"

3.6 V and 14.5 Ah = 52.2 Wh in 107 grams or 487 Wh / kg ...

10 times more than NiCd batteries ...

Unusable for traction, the maximum current is only 2A continuous and 3A for 100ms

You would have to make your own spot welding machine:

I just did the 1st "road" tests ... I'm preparing a post! for the batteries, if you want to assemble a pack from individual elements, you absolutely have to choose models with "tabs" to be able to solder them. Not necessarily because there are "boxes" suddenly ...

Personally, I mounted the hard disk of my decoder in a removable rack that I move on the pc to recover the recordings, it's faster.

ps: it's recording right now

An ordinary charge regulator is content to manage the charge of the batteries without optimizing the recovery of energy. Wiki link please? So it ONLY optimizes at the battery level... so it doesn't work with a PV that wouldn't use a battery (80% of cases)... So say +50% energy c...

Ben it works on the principle of MPPT, managed by micropro. Basically a program optimizes the charge of the batteries in voltage / intensity despite a variable source (solar, wind...) It is considered a must, and it is French Sir. : Mrgreen: Uh you're sure it's French? That's why ...

Elec, I have nothing against the electric car, quite the contrary, but it takes time to set up the infrastructure, train the mechanics... Whereas for the Smile for example, it is applicable immediately, (it was even applicable more than 10 years ago!) and for an affordable price at the g...

today, I discovered this: http://archive.greenpeace.org/climate/smile/index.html The twingo SmILE, it dates from 1996, consumes 3,3 l/100, weighs 650 kg without using to exotic materials. It's just a re-bodied twingo, lighter, and equipped with an optimized engine. She is not even less...
