I bought a E-MAX 120L (VMOTO) Black / Orange a few weeks ago. I Was very Happy.
After a few days of use, the first problems began:
I leave home with 100% batteries;
after a few kilometers (about 5 of which 3 at a constant maximum speed of 65 km / h), the scooter turns off (as if the side stand was inserted), and the display writes "scooter disabled";
I switch it off by turning the key;
Wait a few moments and then restart the scooter;
the batteries mark residual charge 01% - KM residual 00 - but still 54V;
I try to start and the scooter works properly, but display shows wrong charge of (lithium) batteries.
It seems that the problem occurs when you go in MAX mode by holding the handle at most for a little (less than a minute) .... the voltage drops drastically to 46 and the scooter goes out and on the display I read SCOOTER DISABLED.
At this point I must stop completely, turn off the scooter (switch off key) and restart; if I try to do this when riding, it does not solve the problem (probably because of the sensors that detect the motor spinning, as it is not possible to switch from gear to reverse without stopping completely).
could the contacts be? or maybe some cell that goes down short and the control unit reads "0" for a while and then tilt mode?
(sorry for my english, hope you understand me)
please help me!
