I have an E-Max 90S since November 2009
I use lithium mangan batteries 16 cells 30 Ah. After 12687 km in the E-Max 90S and before 2000 km in an other scooter still in good condition.
Now there happened several strange events, so randomly, that I compare it with epilepsy.
June 1: uphill with power button, suddenly power reduced "low battery, charge battery" in display.
Switch off, on
I test several full acceleration with power button, volt drops never below 44,5.
2 km later on a flat street, 50 V shown, suddenly power reduced, "low battery, charge battery" in display.
After about 3 km always switching off and on, again normal operation for the rest of 4 km home.
June 1: it's a little bit downhill, suddenly "low battery, charge battery". After OFF/ON speedometer
shows 10 km/h to much. 60km/h on a flat street, 10 km/h when i have stoped at a traffic light.
June 4: Again on a flat street suddenly "low battery, charge battery", but batteries
are at normal acceleration at 47V.
The normal switch off occurs at 40V.
So I have now 4 times strage problems coming and going like epilepsy.
Any idea what's going on?
