Powercheqs on new Evader
Well, I finally got around to putting Powercheqs on my new Evader scooter, and unlike my old Evader, they seem to work overtime during the charging cycle. My old Evader has a demonstrated range of over 35 miles, and the 4x12Vx35AH battery pack seems well balanced. My new Evader, which is heavier and faster, has a 4x12Vx45AH battery pack, and it's range is under 30 miles. Does the full-time powercheq operation during charging mean that I may have a bad battery in the set?
Could be. Simplest way to check for that is to do a load test on each battery. Depending upon what you have available you can rig something up, like with a coat hanger, car jumper cables, and bucket of water. Or Harbor freight has some cheap load testers.
btw, how fast does your scooter go?
On my e-max, the powercheqs work fairly hard only during the end of the charge cycle when the voltage goes up to 59-60 volts and charging current is low. They also flicker a bit during float as well.
While often justifiably denigrated, the e-max remains among the fastest - and they seem to get faster as they age age. My e-max with 5000 km on it (and a size bigger tires) now does an honest 37 mph on the flat. With the controller modified for 90 amps, it will do 25 mph on grades up to 10%.
