    Bottom balancing?

    Sorry. I did search. "bottom balancing". And it did not come up. Good information. Thanks for finding it for me. I will have to remember to go out to Google for searching Endless-sphere where it would have probably come right up.

    Bottom balancing?

    So these guys on EVTV just bottom balance their big LiFe prismatic packs so that all the cells are 2.75v and then rarely ever have to balance again by choosing a bulk hvc based on an average cell hvc on the low side of 3.65v. Some cells will always bulk charge up to 4.1v while others will be at...

    A123 Nanophosphate white paper

    I haven't seen that happen. Are there any videos of it. I have seen Amp20 cells shot through with a shotgun and cleaved with a hatchet without even getting hot. The shot through one still made 3.2v. It would have been fun to see a capacity test of that one with the giant hole in it. These appear...

    I wired up my Venture Heat 12v glove liners on my CBR250R yesterday. They provide nice heat all around the fingertips.

    What is the difference between Lipo and lifepo4?

    Excellent charge and discharge videos of GBS and A123 cells on youtube. . http://www.youtube.com/watch?v=VxZF8J7wrww . http://www.youtube.com/watch?v=RYOZUteqNEg . . Here are the discharge and charge curves for 8s GBS cells. The A123 Amp20 cells were almost exactly the same voltages. Many people...

    $10 tailbox

    Most excellent! Imagine what the difference would be at 40 mph. I have just bought a (soon to be) dual suspended recumbent. . . . . bike to start on something like this. . . . .

    Battery Purchase idea help!

    $.33 per Wh is a good price for those Winston/ Thundersky cells and matches the give away price we are getting the A123 Amp20 cells for if you need something bigger with terminals and a case.

    The (suspected) truth about VictPower cells

    $21 per cell delivered is a great deal. I will be interested to see how much tab is left when they say they are "short".

    The (suspected) truth about VictPower cells

    What is the cheapest price that you could have gotten your order for, cells and normal shipping? Loose cells or 7S3P modules?

    Aussie 200 Watt Limit Thread

    Believe it or not, ALL e-bikes are illegal in New York state USA. Stupid. The world needs this now. e-cars are way too expensive. New legislation will pass soon to allow 1000 Watts and 23? mph. A good step forward but I can pedal my bike faster than 23 mph. And that is legal up to any posted...

    FAQ - front or rear hub motor?

    Good thread. Just what I needed to know. I'm planning a fast hub motor e-bike conversion for my Performer suspended 26/26 high racer. And was wondering which would you think would make the bike most stable at 40 mph and in crosswinds with a full fairing. Adding the 7.6kg gyro effect of the...
