Hi all, I have problems starting my bike. I fully charged my battery, and when it is loaded into my bike(and connected), I can't seem to start the engine. It did initially show signs of cranking up for a few seconds. But now, all I hear is the rattling sound(going "tat, tat, tat...." as long as i hold the Start button) of a device near my battery. However, the headlight still does turn on. Can anyone help me diagnose this problem? Or does the problem lie with the battery? It is currently having 11.1V. Many thanks to one and all. Cheers.
