Cycle Analyst Info

Introduction:

The stand-alone Cycle Analyst (CA-SA) comes pre-calibrated to a molded shunt resistor (pictured below), a pair of pigtail leads on either side of the shunt simply connect between the vehicle's battery pack and motor controller.

What cycle analyst should I get, Direct Plugin or Stand Alone?

CADP(S) uses controller, or rather shunt resistor built in the controller to measure Amps. A controller must have a 6pin plug for CADP. CASA has its own shunt that is connected to power cable between battery and controler therefore works with any controller.

CADP pros:

• Only one cable and one connector.
• Ability to limit speed and amps, and low voltage cutoff.

CADP cons:

• Must be calibrated to a each specific controller even if two controllers are identical, good chance their shunt resistors are different and will through off CA;s amps and readings and all other readings derived from that (watts, a/h, etc).

CASA pros:

• Factory calibrated, works with any controller and doesn't need to recalibrated.

CASA cons:

• More wiring - shunt box with two connectors.
• Not capable of limiting amps and speed.

Should I use CADP or CADPS for a geared hub motor?

CADPS must be used for geared hub motors like BMC because motor disconnets form a wheel on throttle down - motor's hall sensor can not be used for measuring speed while motor is freewheeling. CADPS uses a separate speedometer sensor cable and spoke magnet to measure speed.

How can I calibrate CADP(S) to the controller?
