Fair cop... Cannot find spelling check for the innured word. The other was the spelling checker giving me the runaround

No. Certainly not! constant voltage means larger currents . The internal resistance of these cells is very small, so a high power constant voltage will drive Hugh current into the cells . Say you had set the constant voltage at 42v and the pack was at 36 V , and the resistance of the pack was...

Actually only the 1.5million Irish in the northern six counties had an opportunity to do so.. the 4.5million in the remaining 26 counties had of course no such opportunity. Of the group which could vote, a convincing majority were remainders. Despite this the policy of the first minister is to...

I come from the Groucho Marx school of thought. I would not want to be a member of a club which would accept me as a member.... One of the advantages of growing older is that one becomes innured to the baseless opinions of others and ploughs ones own furrow. And feels free to make up their...

There is no sorcery involved. Simple science ... The cell will accept voltages of up to 4.2v, ... So 10 in series 42v max etc. Voltages in excess of this willl cause highly undesirable consequences. The lower the charging current the better for longer life and total charge deposit ed but since...

Why are we \ you worrying about the image that e cyclists are lazy? .... What a childish notion. I do not cycle for anyone elses approval.

Any good electronic lab power supply will have, adjustable voltage and adjustable current limits. They are readily available on second hand sites from time to time. New ones can be pretty expensive. Key parameters will be maximum voltage ... Most top out at 60v. And maximum current rating. The...

That is what I would have thought at first also. But the recipe they have caused quite strong binding of the molecular hydrogen with the rare earth .compounds. their product at 5kg gross stores 1500whhr or 500 normalised litres of hydrogen at a pressure of 2megapascal (20bar.). Price is the...

h Yes there's are hydrates which have the capacity to adsorb significant quantise of hydrogen at low pressure. Pregma industry in France sell them and are part of the consortium building electric hydrogen bikes for the French post office. However the pressure is very low and safe and the...

You had scraps cor and lived in a box wow , you were lucky.....

I have taken the opportunity to look at this French retailers website ... You referred to it by name in your first post. They have a 30 day cooling off period for the purchasing of electrical bikes . Your initial failure occurred on day 21 They also refer to their SA V ( service apres vent)...

You never showed them the damaged bike!

One cannot assume that the legal position will be similar in different states so transposing UK practices to other countries with a different history is fraught. If you suffered a head on collision then by definition either you or the other driver was on the incorrect side of the road. From...

I got the tyres replaced on my car recently, the tyre depo as is their custom, placed a flyer in my car advising me to return within a week to ensure that all the nuts are tightened to spec. That is normal practice. If you buy a new car you are advised that the first service is included...

The reason why putting a 7.5amp fuse in would not be a necessary is that if the motor was operating at 50% efficiency you would only be getting 125w of output mechanical power, andll you are entitled to the full 250w . At very low revs the mechanicalpower falls to zero, so you are entitled to...

Mechanical power watts =2 pi torque x revs per second of course torque is relevent . It is the mechanical power which brings the bike up. The hill. Electric power consumed watts current x voltage Efficiency = mechanical power / electric power. When you purchase bike from a...

Do not make the assumption that if an on bike display states consumption is Xwatts that that is the power coming from the motor. It is easy to electrically measure voltage and current and simple for a calculator to multiply these together and produce a number called watts. It is less easy to...

Aah Zlantan, good to see you back, now perhaps you will respond to the question I have on two previous posting asked of you...... This is my third and will be the final time I will bother . See my previous posting...

Fair comment!... Because I'm worth it......

Hi in respect of the problem with your wife's bike. It is normal practice to bring a bike back to the shop after about 6 weeks in order that this type of tweaking can be done. Bikes are subject to a fair amount of vibration and this is to be expected. After this tightening up there should be no...
