i have kind of the same problem. i was mowing perfectly normal and dry grass with my 6ah batterie when one of them ended beeing empty so the mower stopped. I changed the batteries for a pair of 5 ah and the mower never turned back on.
A couples hours later i retried with the 6 ah fully charged. the mower started for 2 seconds and then nothing. checked up the switch on the side if it was stucked, mower is clean underneath, battery sockets are clean, i've let it sit trough the night to retry the next morning, the batteries are fully charged.
the lights indicator turn on like they are supposed to, but nothing else happens, no sound, nothing.
anyone has an idea ??
