    Cycle Analyst VS. Battery Analyzer

    OK, so in one corner we've got the Cycle Analyst from ebikes at a hefty $140 plus shipping
    http://www.ebikes.ca/drainbrain.shtml

    In the other corner, you've got the Wattsup Battery Analyzer weighing in at mere $53.95 plus shipping.

    As far as I can tell, other then the speed meter on the CA, these are the same thing. Please, someone help me out here. Is there any reason I should shell out the extra $100+ (international shipping) for the CA?

    I've got a CA, I can't see the difference. Please report back if you go wattsup, it's always nice to know if there's really a cheaper lunch out there.

    the watt meter works great. until you run anything over the max voltage and pop

    One key difference is that the CA uses a remote shunt (sensor), so you don't have to run big wires from battery-display-motor controller. Not only are the wires bulky, but the extra length means more resistive loss.

    Depends what price a person places on permanent, parasitic resistance losses. unime just made the answer easy for me personally, yes, it's worth the $100.

    i was a click away from ordering the cycle analyst from ebikes.ca when i saw the total over $200 ouch.
    see the Canadian dollar is doing well

    i came up with a idea that works for me and its under $60 i just need one to monitor my voltage anyway nothing fancy. kinda looks like part of a ebike kit
