I just bought a second hand Greenedge CS2 that apparently was little used with only 126miles on the clock. Used it a couple of times and it was fine then rode it about 6 miles to work in heavy rain. When I went to leave work it appeared to be completely dead when I switched it on. Charged it up when I got home for about 15 hours and it was fine when I cycled to work but was flat again when I went to go home. This happened again the next day so I checked the voltage and it was 45.4V (battery states 36V) but still would not switch on. I then charged it for a few hours and tried again but still no power so I put it back on charge overnight. Checked the voltage again at 46.3V re connected battery and it was fine! I notice when the battery is switched off it still shows a voltage of around 23V? I have used it now a few times and it appears ok but I notice condensation in the controller. Any ideas what the problem might be. All the connections look ok.
Thanks
