    Are batteries more expensive than petrol?

    If I would be stupid I would believe you.

    Are batteries more expensive than petrol?

    Batteries make about 1/3 sometimes 1/2 of tthe cost of an LEV. So its viable to get the most cycles out of the pack. That is possible if you buy high drain cells (15A - 20A) and make the pack 20-30% bigger than your maximum commuting need is. So get the Samsung 30Q or 25R or LG HE4 or HG2 they...

    Samsung INR18650-25R cycle test.

    Interesting conclusion. Didn't expected that the rate of discharge have so much impact on cycle life. I am curious to see cycle test for a 80% capacity cycle from the beginning till 500 cycle. So every cycle 2000mAh (@ 1C/1D ) charge and discharge from the beginning rather than fixed voltage...

    Samsung INR18650-25R cycle test.

    How about a cycle test with constant capacity rather than voltage? So instead of charging always from 4.15V to 3.1V. Charge from near empty to 75% (1875mAh) of the initial capacity 2500mAh . Than always cycle 1875mAh till 500cycles.

    Are batteries more expensive than petrol?

    What if your CBR125R bike motor has a hidden fabrication failure that leads to a total loss after a few 1000 miles ?

    Are batteries more expensive than petrol?

    Your assumptions are totaly wrong. Think of a Liion battery as a living thing. It needs care and a good constant environment to serve you for long. 500 cycles than end. LOL seriously? You can get >2000 cycles of about 70%-75% capacity cycles from modern 18650 cells. if you build the battery...

    Are batteries more expensive than petrol?

    Yeah but the picture had also could be a HUB-Zilla or Cromotor.... They can deliver same power as the complicated inefficient ICE and look basically the same. (dont tell the cops) :mrgreen: To the Controller: there are new drives not yet for sale sadly. like the from Lebowsky which dont need...

    Are batteries more expensive than petrol?

    You missed to bring up the resale value from the both systems. Just take a look at these: How many moving parts and points of failure you can see? For the gas engine i have no clue (maybe 20 or 30 or 60?) but the DD hub i know its 2 bearings. Even when batteries would cost double as now i...

    Are the ADAPTTO kit $$$ as people think....?

    There is also always the option to buy a (plug in ready) Pedelec in a supermarket like Aldi for dirt cheap. :D Its also even compliant with the visions from the politicians on how teh electric-bike has to be.... :)

    Samsung INR18650-25R cycle test.

    Maybe it would help to stop discharge at different stages and than after a little resting time measure the voltage under no load?

    Maybe it would help to implement a Pedelec law. Because a little workout in the fresh air is always good. :D

    Quantum Entanglement and "Spooky Action at a Distance"

    If one electron can be two tahn we can double our 250wh/kg 18650 battery to a 500wh/kg battery ! I love quantum mechanics. :D

    Aussie 200 Watt Limit Thread

    If u ask me. I would limit EVERY VEHICLE on public roads to 100km/h. Fatalities would drop by 50% (wild guess...) :mrgreen: If wanna have speed rush go to race track!!!

    Wheelchair with Handcycle

    Optimums for li-ion type batteries is: Charge to 80% slow Discharge not under 10% The lower the discharge rate the better. E.G. for a 20A rated 25R cell 5A peak would mean very long cycles. Avoid temperatures over 40`C and under 10`C . Use insulation in winter and fans in summer. :mrgreen...

    Mind-blowing concept. Tidal power lagoon in Swansea Bay. Powers 120.000 homes for the next 120 years. And costs 1.000.000.000 USD. :mrgreen: YKumDZwLziw EDIT 155.000 homes better explanation :mrgreen: afUIZv-hNrM http://www.tidallagoonswanseabay.com

    Samsung INR18650-25R cycle test.

    But we already know the difference from: Test2: 4.20V >>> 3.10V @ 2.5A (electricbike test voltage +OEM high) Done. Test3: 4.15V >>> 3.10V @ 2.5A (electricbike test voltage, as control) Done. But not if we can get 200 or 50 cycles more if we slow charge with a timer switch over night.

    Samsung INR18650-25R cycle test.

    I would prefer to make Test4 to Test6 because the other both are more interesting. Does electricbike have >=3 fresh batteries left?
