    2WD trike pulling left when accelerating

    I have a three wheeler shown in this build thread with dual QS Motors hub wheels at the rear. Dual Kelly KLS7230S controllers. Resistance throttle to Cycle Analyst 3 and a single throttle control wire from the CA3 to each controller. From a dead stop the trike pulls hard to the left...

    Contactor circuit blowing fuses

    I have a Kelly ZJW 72V/400 amp contactor which powers dual Kelly KLS 7230S controllers and dual QS Motors hub wheels. A few days ago (as some of you may have seen in my post on that issue) I couldn't get the batteries (6 lead acid deep cycle) to charge above 74 volts. Turned out to have been...

    72 volt lead acid pack won't charge over 74 volts

    I have a pack of 6 12-volt deep cycle batteries. These were purchased new in October 2017 but have been sitting while I finished construction of the trike they are in. The batteries all tested around 12.8 volts when new. I did not put these batteries on a charger during the construction...

    Dual QS Motors and one runs "tight"

    I'm running dual 3000W QS Motors wheels on the rear of my trike. In the process of programming the Kelly KLS controllers and Cycle Analyst I put the trike up on blocks so the wheels can freely rotate. I've noticed that one wheel is more difficult to turn by hand than the other and under power...

    Can I wire temp sensors from two hub motors to Cycle Analyst

    I am running two matching QS Motors hub wheels in a three wheeler. The controllers are both Kelly KLS7230S. From what I can gather here on ES, most folks running dual motors only use the sensor in one of the motors hooked to their Cycle Analyst 3. My concern is that the non-wired motor...

    Wiring 3-wire DC/DC converter

    I have a 72 volt battery pack to run my hub motors and am using a dc/dc converter to operate my 12 volt electrical accessories. I'm intending to wire the converter outputs to a 12v battery and then run wires from the 12v battery to the accessories. As I was putting things together I...

    Electric chopper trike build journal

    My goal for this project is to build a commuter vehicle capable of highway speeds (60 mph), a reasonable range (25 miles) and a budget that won’t require a second mortgage ($5K). I have chosen to use a three wheeled trike design for the following reasons: a) I am familiar with it from prior...

    Cycle Analyst wiring, ext. shunt, resistive throttle

    I have searched out a couple threads here which apply to my situation but just want to make sure I have this wiring correct (the CA3 manual is a little over my head in this particular section). I am installing a CA3 on a 72V bike with a Kelly contactor & Kelly KLS7230S controller, Holdwell E...
