Received the Drain Brain on Thursday and spent today installing it on the X1000 scooter. Installation requires splicing the shunt between the batteries and controller and hooking up a wheel sensor. The picture below shows the unit installed on the handlebars:
The drain brain displayes the speed, watts, battery voltage, and distance traveled. It also stores the maximum current drawn and maximum wattage. After using it for a couple charge cycles it can calculate the miles left on a charge. After a brief test, it confirmed the maximum current was limited to about 30 amps, this occured when accelerating up a slight grade.
