Not sure where you saw the word 'Kettle' as I was referring to an Electric Fire.

Confused I think not, as I used Ohm's Law which has been around for a very long time to give me the figures above from the formula that was used in our Science classes. If anyone else wants to have ago then here is a link that will do it for you.... http://www.ohmslawcalculator.com/ohms-law-calculator I also understand that a 500W Motor is stronger than a 250W Motor so the rating is a bit like an Electric Fire as a 1200W fire is stronger than an 800W Electric Fire so consumes more power but warms you up faster if cold. When using the 'Throttle' at Level 1 on a 500W 42V Motor will last longer than if you have a 500W 36V Motor.

500W/36V = 13.9Amps. 500W/42V = 11.9Amps Seems to me that running at a lower voltage increases the power consumption from a battery.

Hi trex, Thank you for your reply and clarification. As the bike has a 42V 500W Motor fitted am I correct in thinking that this will discharge quicker than having a 36V 500W Motor fitted?

Hi Folks, Around a week ago I completed the build of an Electric Bike Conversion for my wife which we are both pleased with the results, her more than me as she is the one who uses it, I am just the 'Engineer'. The Battery Spec is 42V not sure about the Amp Hours. After a 4 hour charge using a 42V 2A Li Ion Charger which has a fully charged Green LED fitted (Red while the battery is charging) the battery on a Voltmeter gave a reading of 41.6V. While the output of the battery charger on the voltmeter read 41.9V. I am not sure if this is on the low side as I get the impression from other threads that when the battery is fully charged the voltage is considerably higher to start with, but having only 41.9V coming out of this battery charger I think that would be a miracle! I would also like to get a spare battery charger and wondered if I should get a 43.8V 2A or stick with the 42V 2A. Any advice would be appreciated please. Thanks
