I connected a power analyzer, Turnigy watt meter, to my skateboard (Fiik clone). Very interesting. Since Evolve say that many manufacturers motors don't put out as much as they specify, I was not expecting so much from my 600 W motor. So I was a bit surprised that it put out more then double. Max output was 1400 W, with topped up batteries. Top current was slightly more then the 40 amp fuse in series with the batteries. The power analyzer is very fast so the top numbers was measured for a period of under a second. But if I go up a hill on fresh batteries, the motor draw around 1000 W continuously. No wonder the motor gets smoking hot. At full throttle on flat ground at top speed, 23 km/h, the motor draw about 600 W.
Unloaded the SLA battery is about 40 V fully charged to 37 V when its not funny anymore. Under max load it gets down to about 32 V breifly.
The 7 Ah batteries delivers between 3 to 4 Ah useful capacity depending on how much hills I have to climb. Pretty normal for SLA.
The battery delivers around 150 Wh of useful energy, what gets me confused is that I only get about 5 to 6 km on that when riding fairly flat roads. I read here that people use a single 6s 5000 mAh Li-Po battery, which in best case can deliver 120 Wh, and go over 10 miles or 17 km. Yes, my board weight 20 kg and I am about 90 kg. But still strange some can go 17 km on 120 Wh and I only 6 km on 150 Wh?
