http://inspiredenergy.com/standard_products/Shipping%20&%20Handling%20Li%20ion%20Batteries%2013-01-01.pdf Page 3 of the report, there is a table to recap current US regulations. Towards the bottom of the table, there is a row concerning typical e-bike shipped with battery. I could not find much...

It true that DGSA consultants' input is required when disposing more than 333kgs of dead batteries, but no mention of good/new batteries from online EU documents.

The thin orange goes to the negative side of the charger.

don't panic. UN38.3 is compulsory when Lithium batteries are transported on their own. The carton must also be correctly labelled. When the battery is shipped with other equipment (installed inside or packed with), separate carton is not required and UN38.3 does not apply if the battery weighs...

you'll need some sort of BMS to limit the spikes and to make sure that the battery cuts out on low voltage (even with just one FET) and should also arrange your cells to 2P to balance the load. There should be a good market for all in one 4V booster packs!

there has been so much progress since 2008: sine wave controller, crank drive, more powerful motors. If oregon renews only the motor and battery, it's still an old electric bike.

Could this PFO be classified as paraglider? while thinking about it, may be it's easier to ride off a cliff to take to the air.

Instead of moving bikes by trailers, tfl should perhaps ask the department of work and pension to employ young job seekers to move these bikes by human power - kill two birds with one stone!

Another possible explanation is over ambitious expansion. These bikes are best use within the very centre of London. As the network grows, there will be bigger demand to move bikes from one location to another and lower average usage, increased maintenance cost.

the only new technology is to optimize polysulphidophosphates formulation, it's already proven to be working and the fabrication side has about the same degree of difficulty as with current batteries and I don't think anyone could claim royalty on the use of LiPSP as electrodes. It could be that...

Oxis uses liquid electrolyte, that's why it got them nowhere. The key step is to replace the liquid electrolyte with a sulphur rich solid, like sound wave, electrons traverse solid lattice at much higher speed than liquid/solid interphase, resulting in at least an order of magnitude lower...

I have no idea. PSP is Lithium based chemistry, so it should be similar to what we have now. I assume that without the liquid, the battery can run much hotter than now, enabling higher charge/discharge current. It will also eliminate the main cause of damage to present e-bike batteries. At...

From I think this may be the revolutionary battery technology we have been waiting for - Page 2 - JREF Forum The amazing ionic conductivity of PSP makes possible elimination of liquid electrolyte, resulting in thinner, lighter cells and better gravimetric energy density. The researchers reckon...

Check that the PAS disc moves when you turn the crank. Then open the controller housing, check that the PAS cable is not disconnected.

The xofo torque sensor output is connected to the throttle control of their sine wave controller (they sell the motor with a 15A controller and LCD as a set), presumably programmed to link the output signal to the motor current. Other than that, their kit still requires brake sensors because the...

So in theory the XOFO output should be better for hill climbing? For example, if I input 10NM at the crank, the Thun would translate it to say 1V, whereas the XOFO outputs say same 1V at 12T at the rear cog, then if I change to 24T at the rear (climbing hill), the XOFO would send out 2V?

How does it compare against a Thun torque sensor or the autotorq fitted on the Momentum?

It's difficult to find replacement cells even if you can identify the weak cell(s). Second problem, you'd need to split open the protective PVC heat shrink sleeving in order to locate the weak cells because on the picture, the balancing wires are not accessible outside your pack. After the...

It looks like a modified spring loaded PAS sensor. Compared to their normal 250W motor, XOFO charge $100 extra for this - a bit over the top? As I was reading the other thread (http://www.pedelecs.co.uk/forum/electric-bicycles/14818-me-bike.html), I am wondering if torque sensor compares well...

I think you have a weak cell in your battery. The connection is good, otherwise you could not have run the bike on no load for hours. Underload, the current surges - causing the voltage of the weak cell to collapse, the BMS cuts power to the controller, turning off the light on the display.
