    I'm not bashing on him in any way. Props to him for building a really nice conversion. I read the post more as academic (hence, "how could he have done better?") Maybe there's more that could be read into that...I haven't been following whatever other disagreements have been going on about LiFePO4, BMS, or whatever.

    I see my bike pop up on other forums and such, I read people's comments and learn from them (or I just ignore them). Emailing him directly would be a nice gesture though.

    Anyway...back to the learnin' stuff:

    From EValbum:

    "22 Thunder Sky LFP-90, 3.20 Volt, Lithium-IonMade in China, and imported to Canada by me."

    So looks like he got them new, and they're dead after about 250 charge cycles.

    And honestly, I don't think what we say here is going to affect his sale (nor do I really care if he actually spent $20k or is inflating the price). I was just pointing out the facts, as I saw them.

    His page says it was last updated 2/16/10. I'm pretty sure he could have put 2000 miles on his bike in two years. As for cost, all the little things add up. Also, he may have had labor costs to machine or design.

    Impossible to justify a build based on the Return On Investment (ROI) alone. I've had a blast making an riding mine - sticking it to the Oil Companies is just icing on the cake.

    At $6K (and counting) and not even 1000 miles yet, I'm still in hot water with the family CFO.

    yeah, cost for a R&D home project is going to be high. I hoped to put $7K into mine, but ended up more like $13K+.

    I had a cost breakdown up until it got around $10K and i was still working on putting the pack together.

    I think my 24 Hi Power lasted about 50 charges before they started to stop cooperating with each other. It might have been the BMS, or asking 3C from them, or just the chemistry of the various cells giving up the ghost at different rates. I don't think those Chinese LiFePo4 batteries were really designed for the abuse that they got.

    the HP cells seem ok (barely) if you never go over 1c with them. Not so good when you have a 5kwh pack you need at least 20kw from.
