So I got my batteries and my charger. It took 6 days. I still paid $57 of shipping!!! ( I was a heavy package, around 4kg (8.8lbs) ) That charger is huge. I can charge four 22.2V(6S) battery at once! That is really nice! My 250W can give 13A at 12V. I will measure with my multimeter see if the charger can deliver that much. I have to be careful because the fuse of my Fluke is 10A!
I just tested the scooter with one battery and I am more then happy with the speed! I hit 30km/h (18-19Mph) which is perfect!
I have a nice video and great data. I am writing a post about it.
