I wasn't really questioning that, I was more concerned about the battery at 30 amps draw. Sent from my HTC One_M8 using Tapatalk

Oops, ...Sorry, ...too many 0's... 10 x 6 = 60 cells! Sent from my HTC One_M8 using Tapatalk

Why do you need 30 amps? At 42 Volts that's 1260 Watts! How many banks of 18360 cells are there in parallel, ...you should not drain any one bank of cells more than 2 x C. Usually C = 2000mA, the better cells can do higher, maybe 2500mA, possibly 3000mA for a short time. So say 5 Amps each bank...

I have a Wattmeter on our eTandem, with just a 250W motor it had peaked at over 380W on our last ride. Have to be careful not to draw more than 2 x C of our small battery cells which with 2 x 10 cell config & C = 2A is about 8A max or 336W at max 42V voltage.

OK, accepted! Thanks Wikipedia quotes the original EU directive 2002/24/EC "Cycles with pedal assistance which are equipped with an auxiliary electric motor having a maximum continuous rated power of 0.25 kW, of which the output is progressively reduced and finally cut off as the vehicle...

The information is correct, it was actually cut and pasted from the govt. website. No mention of 'rated' nor 'contiuous'. It actually says..... the motor shouldn’t have a maximum power output of more than 250 watts !!!!!

It's Wilkes not Wilked!

Sorry if it read wrong, I do mean you are allowed no more than 250w on a tandem, including tricycle.... GOV.UK EU Referendum On Thursday 23 June there will be a vote on the UK’s membership of the European Union. Electric bikes: the rules In Great Britain, if you’re 14 or over you don’t need a...

Hi, We have a DIY eTandem conversion. Only intended as a boost to help us up the hills, it works really well ...though I haven't quite finished my diy regen braking system yet. It has a 250w (not allowed any more on a tandem) basic 3-phase front hub motor with which I had to re-seat all 36...
