I do not think there is any ban on having more than one Bosch battery. It might just be a rationing thing due to demand . In fact Bosch has recently introduced a factory variant using 2 Battery packs linked together giving 1kwhr of energy.

In reference to the Bosch, Yes they are very expensive. Yes they have a number of BMS functions built in, .. history of number of charge cycles state of health of battery real time calculation of energy removed from battery etc. . They also have a specific connector , different from any other...

Hi Whether the OP for this thread read the comments or not. The idea is appealing at first glance and probably a case study by some marketing students. But only at first glance I saw this concept first on another website and formed the same opinions as the other posters.The problems as listed...

Hi I would dearly like to believe you are correct in this , but I am more pessimistic. The Musk factory is talking about 190 dollars per 1kwhr ex factory. When one factors in import duty, transport vat distribution markups and customisation into battery packs I can see a retail price 4 to 5...

Yep the model 7 AVO was some piece of kit. I knew of researchers using it as a programmable resettable fuse. Depending on the range, when ever the needle went beyond full scale. It would trip the cutout. ...

Hi I think that that is a very good question .. but when you ask ... It begs the question ..... compared to what. Anybody interested in renewable energy gets around to the problem of energy storage sooner or later. As point of comparison we can use the Lead acid batteries . They are a...

Hi be fair. That is not what he said. According to that paragon of objective reporting the Sun what he actually said was " we cannot deny or take away the people of Europe's right to express their views , but I think it is not wise to organise that kind of debate .... And he is actually an...

Seriously do you not know?. The answer is that MEPs join groups more closely aligned with their domestic politics. E.g those of a right wing will join such a grouping. However the EP is not as fractious as domestic parliament's and consensus building is more the norm. National MEPs from...

MEPs do represent local constituancies and since there are approximately 750 they give a wide range of opinion, they are directly elected by the EU citizens in each area. Of course they are interested in their own constituancies The commission and it's Commissioners which are selected by...

Zlantan has asked the question at least twice about the necessity of including freedom of movement as one of the four prerequisites for a free market , and I do not think he has been adequately answered. The discussion loops back to discussing personality disorders rather than staying on...

Have looked at your video again. Almost certain that you have a fault in one of the battery cells. Your circuit board is probablytrying to draw 20mA ... A few leds . If even one of the cells is discharged it could have an internal resistance up to 1 Mohm so that the overall voltage is dragged...

I would agree with that. Maybe it's the stance, the Raleigh Motus is very much a high position with large air resistance.... Particularly with an open anorak 20km /hr very easy in touring mode. Needs either a lot of effort to get up to 25km hr in tour or reasonable efforts on turbo...

" May end up with the wife while I ride something with more grunt. I can see this might become an expensive hobby........ best sell something quick....." While not seeking to be rude perhaps this phrasing might be improved. A "ride" has a particular meaning in Ireland

Hi before I purchased my current E bike I did visit a couple of the well regarded Dublin shops, some selling road bikes at 4000 euro . The attitude was either along the lines of ... "You pervert " , why should you want to pervert the purity of cycling. Or you poor benighted soul why would...

In respect of item 1 yes I would consider 2k as a considerable sum and would demand satisation, And I would anticipate that the majority of market would think like me. In respect to item 4 what I had in mind was more about dongles, using excessively high gears and demanding more torque, hill...

Hi not having one of these motors, I am reluctant to comment but there are a number of points being made which deserve comment. 1. It is very unlikely that a person who has spent 2K+ on a prestigious bike brand is going to meekly put it away in a shed. 2. If there is a population of people who...

Hi , Are you not being unfair to the motor manufacturers . Motor manufacturers are pragmatic and unless there is a good reason for change, why would they. Startarting car is an ancillary activity to the purpose of driving it and once one has a satisfactory method of doing so why change...

Hi The EU will not have any difficulty in allowing UK or Chinese or anyone else creating products conforming to the EU standards. But if any country is outside the EU it does not have any input into those standards. As Zlantan has picked up on, standards are a very simple way of restricting...

Connecting a multimeter in current measuring mode across the pins of a 36 v battery was not the wisest action, hopefully all it needs is a replacement fuse. I would like to eliminate the battery pack as a potential problem and means that you need to put a suitable load across it which can...

It takes longer for a new technology to make the transition from lab to mass production than is being assumed. Anyway nanocarbon tubes would be a species of graphene . We can assume that there will be improvements in energy density in future. Motors will not get much better,. they have...
