    Bump. Just realized the full post didnít make it. I updated it with more detail. Price lowered, motivated to sell.

    Probably going to part it out in a few weeks if I canít sell the whole thing.

    Man what a great deal. I wish I had a project that needed one of these.

    Can you confirm if these are the Size6 that can handle a sin/cos resolver?

    Yep you got the idea. More in parallel means more current to charge them at the same C rate.

    That's a good explanation of the best way to do the calculation. But the Curtis and AC20 will make more power of your voltage is higher than 85V. IE a stiff lipo pack could maintain 105V maybe and...

    Ultra Capacitor Drag bike

    Hate to say it, but I don't think it's a good idea. Halfway thru the run you'll be at half voltage and basically half power and decreasing.

    Better off using 30s lipo with 10Ah. Or use some...

    Some guys on DIY have figured out a way to cut the busbars to get a 12s arrangement. I'd love to do a 36s pack with three modules. My bike would only weigh 400lbs with 15kWh

    Glad to see your project moving along. The RSP units do tend to creep up on voltage slightly as their output current drops. Setting them about 0.5V low of full charge is not a bad idea. Do keep in...

    If you're worried then wait until you have an amp meter or shunt on it of some kind. That way you can fully understand what you're throwing at your motor. You could also you a temperature gun and...

    Are you worried about the current going into the motor or coming from the batteries? Because the Leaf cells can easily handle peaks of 450A. I've seen 640A from my pack without sagging to badly.

    Curious. Can you confirm that you can do 150V on the Sevcon? I understand your model is different then mine. I have the 96V model and can do 117.4V max before it won't turn on.

    Yea i collecting another data point would be a good idea. You can also tune the CA voltage reading depending on if you think your meter is more accurate.

    Paul, it won't be the average voltage of the two cells. Voltage is a gradient. If there is a difference in voltage between two cells. Current will flow and the capacity of one cell will decrease...
