As the title says I'm working to add a GRIN DPS + External Shunt onto my Lectric ONE.
Why? Because the standard Lectric speed control - tried thumb throttle first then the rotating throttle - both still act like a light switch. Can't accelerate smoothly away from a stop - just a lurch to practically wide-open throttle. Steady speed on throttle only is a joke; bike speed oscillates like a yoyo.
GRIN says that with their CA3-DPS and a Cycle Analyst molded external shunt I can have full and easy control of the throttle's behavior. It's so annoying that it's worth spending some time and money to fix it!
I have the parts in hand. I plan to put the CA3 in series with my throttle output (it's a Hall throttle BTW) and then all I need is battery voltage to the CA3 and I can try it.
I plan to retain the Lectric controller.
Presently stuck looking for battery voltage source!
I can remove and replace the Pinion drive to get battery voltage, or remove and replace the battery holder to accomplish a similar thing.
The CA3 does not need much current to operate in the throttle-only mode - only the voltage from the battery and apparently a very small current. To quote the manual: the heavy red leads are only a packaging consideration and a convenient means to pick up Vbatt+ for CA power and monitoring; they do not need to carry primary controller power.
So here's a question: is there a simpler, easier way to tap into Vbatt+ on the Lectric ONE? Maybe a used or unused plug near the handlebars?
Thank you in advance for any thoughts/ideas!
