Two years = £3800, buy an s-pedelec. Oh yeah right you can't do that because you are in the UK...

We want photos! We always do...

Yes that is the old law you will be going back to after brexit... :rolleyes:

I use the volts reading and when it shows near 31 V I know I am running on empty. Or 36.5 for the LiPo battery. I don't look at the bars. The best way is a Watt meter on the battery which shows how much you have used and a bit of quick mental arithmetic tells you how much is left because you...

Money buys food...

I think it is all that riding alone in the cold and dark has gotten to him? :rolleyes: Or maybe there is something in the mud? :p

How do the poor make a withdrawal from those banks when they are dying of hunger?

The safety issue is the subject of the first post. I am not trying to sell the idea just saying that it works for me. I keep my LiPos safe in a fire resistant place despite my not mistreating them and making them unstable. My bike is legal, Woosh sold me the 250 W maximum nominative GSM motor...

And they are still drinking harbour water then? Searching for reasons of madness on their side of the water... In other news from Davos worlds eight richest have same wealth as 50% poorest...

Lunacycle is around $700 for a 21 Ah 48 V battery that = $1400 for 42 Ah or 1323 €. HK Graphene 10000 mAh is 94€ a pop so in 2P2S (20 Ah) x 2 = 744€ or just under half. (I corrected above where I had only calculated one 20 Ah pack) Graphene Slightly heavier - about 400g per 20 Ah battery...

You already tried selling tea and that didn't work out so well I believe... :rolleyes:

We have forum members using in excess of 40 Ah. My trike project includes 40 Ah nominative of 44.4 V LiPo, that's 1500 Wh for 744 € and which can be charged from empty in just over 2 hours. I am still looking for a Li-ion battery that has those specs for that price. It will be using a 250 W...

Who? They don't know what they are talking about. Batteries can be legally up to 48 V nominative (54.6 V hot off the charger). You have the legal obligation to restrict the speed at which assistance cuts off to 25 km/h/ I agree that a sine wave controller and LCD with 5 levels of power...

https://www.engadget.com/2017/01/15/built-in-flame-retardant-lithium-ion/ If you can remove the fire risk from the LiPo equation their advantages must out number their shortcomings? (modern, lighter more energy dense LiPo d8veh :))

You who are in the recumbent world what do you think of the Azubs? Quality OK? The make a rolling trike chassis at just over 1800€ and I just happen to have a rear wheel with a mxus...

I thought about that for quite a while and came to the conclusion that it was just as easy to swap batteries. The advantage of having the batteries in parallel is less sag on the hills.

Wippermann Connex for me, less than 10€, stay away from the budget KMC chains (the brown ones) they don't wear well.

I have a Samsung celled 10.4 Ah battery that is down to 80% capacity after 18 months. I put that down to drawing massive Amps on long steep climbs regularly rather than charging to 42 V. If you look further into online docs on battery life you will find that asking too much from a battery is...

£52, ladies and gents we have a bidding war! :)
